    Effective management of building maintenance is a vital ingredient in ensuring a high quality built environment for any building's occupiers. However, maintenance is not high on the list of priorities for most organisations. Communication between top management personnel looking at maintenance issues from a strategic standpoint and maintenance staff considering them at an operational level is often not as good as it should be. When planning maintenance activities maintenance personnel often draw too heavily on their technical experience and expertise without taking sufficient account of wider organisational objectives or consulting effectively with top management. Senior managers also regularly complain about lack of managerial input from maintenance departments. Such barriers contribute to communication difficulties between top management at a strategic level and maintenance personnel at an operational level. Identifying where the key differences lie in senior managers' and maintenance personnel's viewpoints on maintenance strategy can prove invaluable in achieving some convergence of opinions and optimising the efficiency of the overall building maintenance process.

    Full Text Available University buildings are a significant part of university assets and considerable resources are committed to their design, construction and maintenance. The core of maintenance management is to optimize productivity and user satisfaction with optimum resources. An important segment in the maintenance management system is the analysis of criteria that influence building maintenance. Therefore, this paper aims to identify quantify, rank and discuss the criteria that influence maintenance costs, maintenance backlogs, productivity and user satisfaction in Malaysian university buildings. The paper reviews the related literature and presents the outcomes of a questionnaire survey. Questionnaires were administered on 50 university maintenance organizations. Thirty-one criteria were addressed to the university maintenance organizations to evaluate the degree to which each of the criteria influences building maintenance management. With a 66% response rate, it was concluded that the consideration of the criteria is critical to the university building maintenance management system. The quality of components and materials, budget constraints and the age of the building were found to be the most influential criteria but information on user performance satisfaction, problems associated with in-house workforce and shortage of materials and components were the least influential criteria. The paper also outlined that maintenance management is a strategic function in university administration.

    This paper reports the preliminary results of a study of the software maintenance process in the Flight Dynamics Division (FDD) of the National Aeronautics and Space Administration/Goddard Space Flight Center (NASA/GSFC). This study is being conducted by the Software Engineering Laboratory (SEL), a research organization sponsored by the Software Engineering Branch of the FDD, which investigates the effectiveness of software engineering technologies when applied to the development of applications software. This software maintenance study began in October 1993 and is being conducted using the Quality Improvement Paradigm (QIP), a process improvement strategy based on three iterative steps: understanding, assessing, and packaging. The preliminary results represent the outcome of the understanding phase, during which SEL researchers characterized the maintenance environment, product, and process. Findings indicate that a combination of quantitative and qualitative analysis is effective for studying the software maintenance process, that additional measures should be collected for maintenance (as opposed to new development), and that characteristics such as effort, error rate, and productivity are best considered on a 'release' basis rather than on a project basis. The research thus far has documented some basic differences between new development and software maintenance. It lays the foundation for further application of the QIP to investigate means of improving the maintenance process and product in the FDD.

    The Do-It-Now (DIN) building maintenance system is proposed to reduce the cost of routine building maintenance and repairs and to improve customer satisfaction with maintenance services. DIN uses a team approach to periodically inspect buildings and provide maintenance services on the spot. It emphasizes communications between the customers and the craftspeople performing the work. The system was designed using a reengineering approach that characterized the existing maintenance work control system, analyzed comparable systems in other DOE laboratories, envisioned an ideal system, and proposed a workable, testable system for initial implementation. At each stage, input was solicited from customer representatives and Facilities management to ensure meeting customer requirements with an implementable system.

    Building information modeling (BIM) is a digital representation of the physical and functional properties of a building; it has been used by construction professionals for a long time and stakeholders are now using it in different aspects of the building lifecycle. This paper intends to present how BIM impacts the construction industry and how it can be used for facility maintenance management. The maintenance and operations of buildings are in most cases still managed through the use of drawings and spreadsheets although life cycle costs of a building are significantly higher than initial investment costs; thus, the use of BIM could help in achieving a higher efficiency and so important benefits. This study is part of an ongoing research project, the nD modeling project, which aims at predicting building energy consumption with better accuracy.

  3. Significance of Building Maintenance Management on Life-Span of Buildings

    2017-06-01

    Full Text Available The attentions and skills of maintenance are required for the construction of buildings in this twenty-first century. Because much architectural education is still focused on the one-of-a-kind assignment, encouraging the notion of personal fulfillment through leaving a mark for off-springs and obtaining a design award by means of concept drawings. Due to the reason that many building designers (architects, engineers, technicians are not encompassed in the subsequent maintenance of the building, they just regard it as other specialists’ responsibilities. In all likelihood, the building user-to-be has no formal role: the building contractors just fulfill their accountabilities to complete the building in compliance with the contract documents, not to care occupier’s needs and wants. This paper will focus on the important of building maintenance management on the life-span of buildings.

    Full Text Available Building maintenance is considered as one of the national agenda. Multitude barriers received by the services providers have undergone various difficulties in satisfying public interest have been progressively resolved as a sign towards becoming a more developed country. In real practice, building maintenance is the thing which we mostly tolerate. If the building is able to weather the elements, we may with delay taking action on it. Most buildings are always treated with ‘ad-hoc’ maintenance. In some instances, the building disrepair will wait until complaints are made before any repair work is done. It shows that the situation is not considered critical as it may. Maintenance is still being practiced in improper procedure by the maintenance managers which subsequently caused bad impacts to the facilities and the services provided. It can be seen that the managers prefer carrying out reactive maintenance works rather than proactive works and at times do not consider the clients satisfaction and also the performance of services. This paper will focus on some important elements of building maintenance and its relation to building performance holistically.

    2016-01-01

    Full Text Available Heritage buildings represent the tangible cultural heritage of a community. However, many of the heritage buildings have being left neglected. Ipoh as a city rich in heritage, has many dilapidated heritage buildings which are experiencing a resurging interest. However, the problems faced by many owners are the lack of technical information of such buildings, leading to premature abandonment and demolition. Therefore, the objectives of this study are to determine the types and extent of defects present in the building studied. To achieve these objectives, a case study of a century old heritage property in Ipoh, Perak was conducted. The study aims to provide reference to owners and those responsible for the conservation of heritage buildings with similar conditions to identify and prioritize critical defects in relation to the building life span to determine its condition. The findings determined the probable causes of defects such as settlement and façade cracks, which are over 30 years old, were attributed to leaking plumbing pipes, rainwater ingress and the construction of an adjacent 20 story apartment building. The major issues to address were stabilizing the foundation through cement grouting, reinforcing the existing structural systems and roof systems as well as arresting the decay of timber floor structure. In conclusion, major maintenance guidelines are need to address structural issues and weather tightness of the building envelope, especially its roof and drainage systems.

    2014-01-01

    Full Text Available The study of biomimetic architecture on building envelope is the main structure of this research. The concept is believed more sustainable and efficient for energy saving, operating cost consumption, waste recycle and design renewal in the future. The inspiration from the nature developed the intention on this study to explore on what and how this concept to overcome the problems through design. Biomimicry does catch the attention of human to study more on the system and function of its nature course. The designers are not exception influenced by this concept when the form, shape, texture and colour inspired them in their design. The domination of building form will affect the building envelope as the skin of the structure. A clear impact on building failure is begun with building envelope appearance without a proper maintenance. The faults in building design place a heavy burden on the building for the rest of its operational life and there is no compensation for it. In such situations, the responsibility falls on the shoulders of the designer.

    This document provides a plan for implementing surveillance and maintenance (S and M) activities to ensure that Building 9401-2 Plating Shop is maintained in a cost effective and environmentally secure configuration until subsequent closure during the final disposition phase of decommissioning. U.S. Department of Energy (DOE) G430.1A-2, Surveillance and Maintenance During Facility Disposition (1997), was used as guidance in the development of this plan. The S and M Plan incorporates DOE O 430.1A, Life Cycle Asset Management (LCAM) (1998a) direction to provide for conducting surveillance and maintenance activities required to maintain the facility and remaining hazardous and radioactive materials, wastes, and contamination in a stable and known condition pending facility disposition. Recommendations in the S and M plan have been made that may not be requirement-based but would reduce the cost and frequency of surveillance and maintenance activities. During the course of S and M activities, the facility's condition may change so as to present an immediate or developing hazard or unsatisfactory condition. Corrective action should be coordinated with the appropriate support organizations using the requirements and guidance stated in procedure Y10-202, Rev. 1, Integrated Safety Management Program, (Lockheed Martin Energy Systems, Inc. (LMES), 1998a) implemented at the Oak Ridge Y-12 Plant and the methodology of the Nuclear Operations Conduct of Operations Manual (LMES, 1999) for the Depleted Uranium Operations (DUO) organization. The key S and M objectives applicable to the Plating Shop are to: Ensure adequate containment of remaining residual material in exhaust stacks and outside process piping, stored chemicals awaiting offsite shipment, and items located in the Radioactive Material Area (RMA); Provide access control into the facility and physical safety to S and M personnel; Maintain the facility in a manner that will protect the public, the environment, and

  18. Balancing building and maintenance costs in growing transport networks

    Bottinelli, Arianna; Louf, Rémi; Gherardi, Marco

    2017-09-01

    The costs associated to the length of links impose unavoidable constraints to the growth of natural and artificial transport networks. When future network developments cannot be predicted, the costs of building and maintaining connections cannot be minimized simultaneously, requiring competing optimization mechanisms. Here, we study a one-parameter nonequilibrium model driven by an optimization functional, defined as the convex combination of building cost and maintenance cost. By varying the coefficient of the combination, the model interpolates between global and local length minimization, i.e., between minimum spanning trees and a local version known as dynamical minimum spanning trees. We show that cost balance within this ensemble of dynamical networks is a sufficient ingredient for the emergence of tradeoffs between the network's total length and transport efficiency, and of optimal strategies of construction. At the transition between two qualitatively different regimes, the dynamics builds up power-law distributed waiting times between global rearrangements, indicating a point of nonoptimality. Finally, we use our model as a framework to analyze empirical ant trail networks, showing its relevance as a null model for cost-constrained network formation.

    The scope of this paper was to evaluate the provision of building maintenance services in health units, by means of a descriptive, quantitative and cross-sectional study, considering the five types of facilities (Primary Health, Emergency, Specialty, Hospital and Mental Health Units). The research was approved by the Research Ethics Comittee of FHEMIG with the Terms of Agreement signed with the Unified Health System of Betim. Comparative analysis was conducted by checking the requirements of "Physical-Functional Structure Management" of the "Brazilian Hospital Accreditation Manual" of the National Accreditation Organization. Nonconformities were noted in the physical-functional management of the health centers, especially the primary health units. The assessment was important, considering that compliance with formal, technical and structural requirements, welfare activities, according to the service organization and appropriate to the profile and complexity, can collaborate to minimize the risks of users. To improve the quality of health care establishments, it is essential that managers, backed by "top management," prioritize financial, human and material resources in planning to ensure compliance with security requirements of users in buildings.

  1. Study on Maintenance Practices for School Buildings in Terengganu and Kedah, Malaysia

    2014-03-01

    Full Text Available Malaysia initiated talks on building maintenance in 1971 during the Second Malaysia Plan of 1971-1975. Later, the government introduced the Building and Common Property (Maintenance and Management Act, 2007 to provide proper maintenance and management of buildings. School buildings are one of the important facilities for basic knowledge in everyday life. Accordingly, the maintenance of school buildings, which serve staff and students, needs considerable attention as effective maintenance protects capital investment, ensures the health and safety of the children, and supports educational performance. Based on a combination of literature survey and questionnaire appraisal, this study evaluates the maintenance practices in designated schools in Malaysia. Overall, the study showed that most of the school buildings do not possess their own maintenance management practices. Moreover, no preventive or planned maintenance was observed, and only emergency maintenance was applied when necessary. The study recommends the implementation of planned maintenance practices, which will be more effective than unplanned maintenance, mostly because of the reduction in repair costs.

    Full Text Available University buildings require maintenance in order to create a conducive environment that supports and stimulates learning, teaching, innovation, and research. The prime objective of maintenance is to ensure, as far as practicable, the continued peak performance of the building throughout its design life. This paper seeks to report the maintenance management system of a university institution in Malaysia. Primary data was gathered through the analysis of a case study. The objectives of the case study are to identify, describe and assess the maintenance management system used by the university. The major conclusion drawn from the case study was that although university building maintenance practices are corrective and cyclical there is a lack of a comprehensive maintenance management framework that guides the decision-making processes. The case study also revealed irregularities in the university’s maintenance management system.

    Full Text Available Effectiveness of management in maintenance aspect holds the key element in influencing the performance of overall maintenance management. Similarly, public hospital building needs an effective maintenance management as this type of building in nature is one of the most complex issues in the field of maintenance. Improper building maintenance management adopted by the organization significantly will interrupt the overall operation of the building. Therefore, this paper is aim to identifying the key performance indicator (KPI of effectiveness of maintenance management for the public hospital building. A total of 32 set of questionnaires were distributed to the maintenance manager for each hospital in the northern region of peninsular Malaysia by using self-administration strategy. The survey answer was analyzed by performing descriptive analysis in SPSS. Overall, the result of descriptive analysis shows that all the ten factors of effectiveness of maintenance management are accepted as KPI since the mean value is at least 3.93 which classified as important and significant. The most significant factor of effectiveness of maintenance management is task planning and scheduling with the mean score of 4.35. While less significant factor is identify as maintenance approach with the value of mean score is 3.93. The both results indicates that the management need to have well-structured planning for the maintenance works and also need to embrace the exact strategy of maintenance approach in order to achieved better overall performance of maintenance management. This study may draw a standard practice for the government in assessing the performance of public facilities in terms of maintenance management.

    The current building maintenance practices in Palestine are not based on scientific systematic methods. Most of the municipalities use one criterion to define the maintenance priorities, which is the "worst-first" criterion. Therefore, the current practices in defining buildings maintenance plans are not dealing with the known phases that are generally followed, including those in establishing building inventories, building condition survey, detailed visual inspection, identification of the proper maintenance and rehabilitation measures, and setting priorities. Accordingly, the recent preparation of the Operation and Maintenance (O&M) Manual for Palestinian municipalities is an important step to guide them towards preparing and implementing their O&M priority-based plans, considering scare resources. During the course of preparation of the Manual, the proposed procedures were applied at ten pilot municipalities. This study aims to explore the outcome of the implementation of the 2014/2015 O&M buildings maintenance priorities at these municipalities through the development of maintenance composite priority index (PI). The new proposed priority index is a scientific tool that will identify the priority of maintenance buildings through using a systematic procedure instead of first worst one. To achieve this, analyses of the outcome of a questionnaire designed to collect relevant information from these municipalities was conducted. The maintenance priority index for buildings is calculated considering different indicators among them building status (condition), classification and importance of the building, number of beneficiaries (users), safety aspects (severity level in the building), and people complaints. The main component of the PI is the building condition index (BCI) which forms about 40% of the total weight. The physical inspection, which is the main input for calculating the BCI, is conducted on two levels; the primary level, and the secondary level. The

    Full Text Available Urges for sustainable development had pushed the government and professional bodies to respond and react by implementing regulations where possible to direct development in that manner. However, the outcome in most financial conferences and dialogues on sustainable buildings flagged on high construction and maintenance cost. Thus, this study is conducted to collect and analyze actual building operation and maintenance cost between GBI and Non-GBI rated buildings in Malaysia which are more than 2 years fully operated buildings. There are two categories of selected buildings which are residential and non-residential type of building. Each category of the building consists of similar building’s characteristic such as geographic location, mode of operation, building heights, total numbers of floors and units. The scope of building’s maintenance for this study is mainly on wear and tear of the wall painting, electrical light fittings, ceiling panels, roofing system and mechanical services like water pump system are recorded for their replacement frequency of service and the cost involved within a consistent period of 12 months operation at cost percentage saving of 78.9% and 40.4% for residential and non-residential buildings respectively compare against Non-GBI rated buildings. Electricity consumption for GBI rated buildings are lower than Non-GBI rated buildings which recorded at the cost variance of 23.8% and 6.3% and water consumption at 35.9% and 44.0% for the above mentioned two main categories of selected case study buildings. Results from this study conclude major savings on residential buildings category in term of maintenance cost and electricity consumption for GBI rated buildings. Whereby, non-residential category of buildings, GBI rated building had been proven to obtain significant savings in terms of maintenance cost and water consumption.

    Ferdinando Salata

    2015-08-01

    Full Text Available Proper lighting is vital to improve, from an artistic point of view, the surface expanse and decorative detailing of architectural heritage buildings considered valuable. When properly lit, monumental buildings can become to onlookers an essential part of the city. Nowadays, for design planners dealing with the improvement of buildings, whose architectural design should be valorized, the real challenge is to combine the lighting artistic requirements with scrupulous economic management in order to limit the energy demand and to respect the environment. For these reasons, this case study examines the lighting of the monumental façade and the cloister of St. Peter in Chains situated in the Faculty of Engineering of Sapienza University of Rome. The present lighting installation, characterized by metal halides, compact fluorescent and halogen lamps, is compared with an alternative scenario presenting LED lamps and scenographic lighting of the monumental façade. Such comparison is based on the evaluation of the lighting levels for different visual tasks and on energy and maintenance issues; the first analysis was performed through the software DIALux Evo 4.0, whereas the second was performed using ecoCALC. This study leads to the conclusion that the lighting levels of the solution presenting LED lamps are better than those of the present solution, and they comply with current standards. Finally, the higher costs of LED lamp installations and the scenographic lighting of the monumental façade are balanced by lower maintenance costs, with a payback period of seven years.

    This research's main goals were to build a predictor for a turnaround time (TAT) indicator for estimating its values and use a numerical clustering technique for finding possible causes of undesirable TAT values. The following stages were used: domain understanding, data characterisation and sample reduction and insight characterisation. Building the TAT indicator multiple linear regression predictor and clustering techniques were used for improving corrective maintenance task efficiency in a clinical engineering department (CED). The indicator being studied was turnaround time (TAT). Multiple linear regression was used for building a predictive TAT value model. The variables contributing to such model were clinical engineering department response time (CE(rt), 0.415 positive coefficient), stock service response time (Stock(rt), 0.734 positive coefficient), priority level (0.21 positive coefficient) and service time (0.06 positive coefficient). The regression process showed heavy reliance on Stock(rt), CE(rt) and priority, in that order. Clustering techniques revealed the main causes of high TAT values. This examination has provided a means for analysing current technical service quality and effectiveness. In doing so, it has demonstrated a process for identifying areas and methods of improvement and a model against which to analyse these methods' effectiveness.

    2013-04-01

    Many newly constructed green buildings (GB) are certified using the United States Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) rating system for new construction and major renovation which focuses on architectural and mechanical design to conserve energy, reduce environmental harm, and enhance indoor quality for occupants. This study evaluated the preventive maintenance (PM) worker occupational safety and health (OSH) risks related to the design of GB. PM job hazard analyses (JHA) were performed on the tasks required to operate and maintain five GB features selected from 13 LEED certified GB. A 22-item JHA and OSH risk scoring system were developed. Potentially serious OSH hazards included: green roofs made of slippery material without fall protection; energy recovery wheels and storm water harvesting systems in confined spaces; skylights without guard rails; and tight geothermal well mechanical rooms constraining safe preventive practices. GB can present PM OSH risks and these should be eliminated in the building design phase. Copyright © 2013 Wiley Periodicals, Inc.

  2. Relationship between Quality of Building Maintenance Management Services for Indoor Environmental Quality and Occupant Satisfaction: Case Study of Bus Terminal Buildings in Penang

    2014-01-01

    Full Text Available Maintenance is often defined as the series of activities undertaken to take care of the building structure and services to ensure the intended functions and optimal performance of a building life cycle. The management department of a building is usually responsible for the enhancement of the indoor environment quality by service delivery and for boosting occupant productivity and satisfaction. Thus, a salient point of this study is to determine the current level of the building’s maintenance management service for indoor environmental quality in Penang bus terminals, along with its occupant satisfaction with regards to the services provided in the building. The assessment of the indoor environmental quality includes the evaluation of thermal comfort, lighting condition, air quality and cleanliness. Apart from that, qualitative and quantitative methodologies were applied during the process of data collection and analysis. A questionnaire survey was distributed to 500 of the targeted population for each bus terminal, including passengers and the staff. In this study, the conclusion was drawn in which the maintenance management service level of the bus terminal was directly proportional to occupant satisfaction. However, the current quality of maintenance management services in the bus terminals are still not up to the level of the occupants’ satisfaction.

    This study aimed to clarify indoor air pollution levels of volatile organic compounds (VOCs), especially 2-ethyl-1-hexanol (2E1H) in large buildings after revising of the Act on Maintenance of Sanitation in Buildings in 2002. We measured indoor air VOC concentrations in 57 (97%) out of a total of 61 large buildings completed within one year in half of the area of Nagoya, Japan, from 2003 through 2007. Airborne concentrations of 13 carbonyl compounds were determined with diffusion samplers and high-performance liquid chromatography, and of the other 32 VOCs with diffusion samplers and gas chromatography with a mass spectrometer. Formaldehyde was detected in all samples of indoor air but the concentrations were lower than the indoor air quality standard value set in Japan (100 microg/m3). Geometric mean concentrations of the other major VOCs, namely toluene, xylene, ethylbenzene, styrene, p-dichlorobenzene and acetaldehyde were also low. 2E1H was found to be one of the predominating VOCs in indoor air of large buildings. A few rooms in a small number of buildings surveyed showed high concentrations of 2E1H, while low concentrations were observed in most rooms of those buildings as well as in other buildings. It was estimated that about 310 buildings had high indoor air pollution levels of 2E1H, with increase during the 5 years from 2003 in Japan. Indoor air pollution levels of VOCs in new large buildings are generally good, although a few rooms in a small number of buildings showed high concentrations in 2E1H, a possible causative chemical in sick building symptoms. Therefore, 2E1H needs particular attention as an important indoor air pollutant.

  7. Maintenance and Expansion: Modeling Material Stocks and Flows for Residential Buildings and Transportation Networks in the EU25.

    Wiedenhofer, Dominik; Steinberger, Julia K; Eisenmenger, Nina; Haas, Willi

    2015-08-01

    Material stocks are an important part of the social metabolism. Owing to long service lifetimes of stocks, they not only shape resource flows during construction, but also during use, maintenance, and at the end of their useful lifetime. This makes them an important topic for sustainable development. In this work, a model of stocks and flows for nonmetallic minerals in residential buildings, roads, and railways in the EU25, from 2004 to 2009 is presented. The changing material composition of the stock is modeled using a typology of 72 residential buildings, four road and two railway types, throughout the EU25. This allows for estimating the amounts of materials in in-use stocks of residential buildings and transportation networks, as well as input and output flows. We compare the magnitude of material demands for expansion versus those for maintenance of existing stock. Then, recycling potentials are quantitatively explored by comparing the magnitude of estimated input, waste, and recycling flows from 2004 to 2009 and in a business-as-usual scenario for 2020. Thereby, we assess the potential impacts of the European Waste Framework Directive, which strives for a significant increase in recycling. We find that in the EU25, consisting of highly industrialized countries, a large share of material inputs are directed at maintaining existing stocks. Proper management of existing transportation networks and residential buildings is therefore crucial for the future size of flows of nonmetallic minerals.

    Faghihinia, Elahe; Mollaverdi, Naser

    2012-08-01

    A major competitive advantage of production and service systems is establishing a proper maintenance policy. Therefore, maintenance managers should make maintenance decisions that best fit their systems. Multi-criterion decision-making methods can take into account a number of aspects associated with the competitiveness factors of a system. This paper presents a multi-criterion decision-aided maintenance model with three criteria that have more influence on decision making: reliability, maintenance cost, and maintenance downtime. The Bayesian approach has been applied to confront maintenance failure data shortage. Therefore, the model seeks to make the best compromise between these three criteria and establish replacement intervals using Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE II), integrating the Bayesian approach with regard to the preference of the decision maker to the problem. Finally, using a numerical application, the model has been illustrated, and for a visual realization and an illustrative sensitivity analysis, PROMETHEE GAIA (the visual interactive module) has been used. Use of PROMETHEE II and PROMETHEE GAIA has been made with Decision Lab software. A sensitivity analysis has been made to verify the robustness of certain parameters of the model.

    2012-01-01

    Lamins are the major structural components of the nuclear lamina found in metazoan organisms. Extensive studies using tissue culture cells have shown that lamins are involved in a wide range of basic cell functions. This has led to the prevailing idea that a given animal cell needs at least one lamin protein for its basic proliferation and survival. However, recent studies have shown that lamins are dispensable for the proliferation and survival of mouse embryonic stem cells (ESC). In contrast to a lack of essential functions in ESCs, certain differentiated cells lacking B-type lamins exhibit increased cell cycle exit rates and enhanced senescence. In this Extra View, we discuss how studies using animal models and cell cultures have begun to reveal cell-type specific functions of lamins in tissue building and homeostasis.

    2007-07-31

    From July 2005 to July 2007, the Schatz Energy Research Center (SERC) assisted the Yurok Tribe in the implementation of a program designed to build the Tribe’s own capacity to improve energy efficiency and maintain and repair renewable energy systems in Tribal homes on the Yurok Reservation. Funding for this effort was provided by the U.S. Department of Energy’s Tribal Program under First Steps grant award #DE-FG36-05GO15166. The program’s centerpiece was a house-by-house needs assessment, in which Tribal staff visited and conducted energy audits at over fifty homes. The visits included assessment of household energy efficiency and condition of existing renewable energy systems. Staff also provided energy education to residents, evaluated potential sites for new household renewable energy systems, and performed minor repairs as needed on renewable energy systems.

    Abstract Problem China’s National Methadone Maintenance Treatment Programme (MMT) has expanded from eight clinics serving approximately 1000 clients to 738 clinics that have served more than 340 000 clients cumulatively in only 8 years. This has created an enormous demand for trained providers. Approach Human resource development and capacity building efforts have been conducted in China’s National MMT Programme to create a supply of providers trained in administering MMT for opioid dependence. Local setting From 2004 to 2007, China’s National MMT Programme faced several problems: inappropriately low methadone doses, poor compliance, high concurrent drug use and high drop-out rates among clients, and little experience, little training and high turnover rates among providers. Relevant changes Training programmes for individual providers and their trainers were redeveloped and expanded in 2008. Although programme performance metrics show an increase in patients’ annual mean duration in treatment (93 days in 2004 versus 238 days in 2011), the increase in their mean daily methadone dose (from 47.2 mg in 2004 to 58.6 mg in 2011) is modest. Lessons learnt Some of the problems that can arise during the development, launch and scale-up of a major national public health effort, such as China’s National MMT Programme, cannot be foreseen. Key to the programme’s success so far have been the strong commitment on the part of China’s government and the optimism and pragmatism of programme managers. Human resources development and capacity-building during scale-up have contributed to improved service quality in MMT treatment clinics and are critical to long-term success. PMID:23554525

    In this issue, Lipner and colleagues describe research supporting the value of the examinations used in the maintenance of certification (MOC) programs of the American Board of Internal Medicine and the American Board of Surgery. The authors of this commentary review the contribution of this research and previous investigations that underscore the value of this component of the American Board of Medical Specialties (ABMS) MOC program. In addition, they point out that the MOC examination is one element of a comprehensive approach to physician lifelong learning, assessment, and quality improvement. The ABMS MOC program requires diplomates of the ABMS member boards to engage in continuous professional development in the six domains of competence and performance previously defined by the ABMS and the Accreditation Council for Graduate Medical Education. Although evidence and a sound rationale exist to support educational and assessment methods that target all six domains, it will be important to continue to build the body of evidence demonstrating the value of MOC to the public and to the profession.

    Full Text Available In high-rise residential buildings, the quality of facilities management services is significant to the normal operation of the facilities. Unfortunately, lack of concern towards building maintenance, especially preventive maintenance, happens in domestic housing industry in Malaysia. Majority of the maintenance operations of condominiums suffer from lack of planning, lack of proactive maintenance plan, and lack of proper implementation. Thus, this paper reviews the implementation of preventive maintenance strategy, routine maintenance in specific. An extensive review of literature published in 1987 to 2014 is performed for the purpose of this research. The publications are sourced from journal articles, conference proceedings and books. The literature analysis confirms that the routine maintenance of facilities and building services is vital and it can be influential towards the maintenance performance. Subsequently, a theoretical framework is developed, which shows the relationship between routine maintenance of building facilities & services and maintenance performance. The building facilities & services are divided into two categories. They are essential facilities & services that ensure the safety, health, habitability, and operability of buildings; while value-added facilities & services deal with property value, return on investment, and quality living of buildings. Based on the findings, a future research is proposed, which aims to identify the appropriate routine of maintenance for the facilities and services in high-rise residential buildings to improve the maintenance performance.

    Full Text Available Cities are responsible for 60%-80% of the world’s energy use and for approximately the same percentage of greenhouse gas emissions. The existing multi-apartment buildings of multifamily housing sector are often energy inefficient, and the heating system does not ensure optimization of heat distribution of individual apartments. Heat distribution, heating system balancing, heat loss detection and calculation, individual heat energy accounting are difficult tasks to accomplish. This article deals with the temperature monitoring system designed to retrieve temperature differences necessary for overall building heat monitoring and individual apartment monitoring. The sensor testing case study process and its measurements are analysed.

    This Streamlined Approach for Environmental Restoration (SAFER) Plan addresses the action necessary for the closure in place of Corrective Action Unit (CAU) 113 Area 25 Reactor Maintenance, Assembly, and Disassembly Facility (R-MAD). CAU 113 is currently listed in Appendix III of the Federal Facility Agreement and Consent Order (FFACO) (NDEP, 1996). The CAU is located in Area 25 of the Nevada Test Site (NTS) and consists of Corrective Action Site (CAS) 25-04-01, R-MAD Facility (Figures 1-2). This plan provides the methodology for closure in place of CAU 113. The site contains radiologically impacted and hazardous material. Based on preassessment field work, there is sufficient process knowledge to close in place CAU 113 using the SAFER process. At a future date when funding becomes available, the R-MAD Building (25-3110) will be demolished and inaccessible radiologic waste will be properly disposed in the Area 3 Radiological Waste Management Site (RWMS).

    The SINUS project intended to support building availability by regular maintenance, to reduce environmental pollution and waste production during the building life, to save natural resources, and to draw up a practical manual for this purpose. the findings were supported by tests on pilot plants and selected reference systems. [German] Primaeres Ziel des SINUS Projektes war es, die umweltgerechte Herstellung von nutzerorientierter Verfuegbarkeit von Gebaeuden durch eine nachhaltige Instandhaltung zu unterstuetzen, Umweltbelastungen waehrend der Betriebs-/Gebrauchsphase zu reduzieren, Stoffstroeme zu verringern, natuerliche Ressourcen zu schonen und die Ergebnisse in einem Handbuch des 'Integrierten Gebaeudeinstandhaltung und Umweltschutz Management Systems' abzubilden (siehe Schlussbericht Kapitel 2). Um die Praxistauglichkeit der Forschungsergebnisse zu gewaehrleisten, wurden diese staendig durch die Umsetzung an Pilotanlagen und ausgewaehlten Referenzsystemen evaluiert (siehe Schlussbericht Kapitel 5.3, 5.5). Es konnte einerseits detailliert dargelegt werden, dass sich erhebliche Synergieeffekte bei der Integration von Instandhaltung und Umweltschutz erzielen lassen (siehe Schlussbericht Kapitel 4,5). Andererseits wurde deutlich, dass Instandhaltung an sich angewandter Umweltschutz ist. Es wurden Methoden, Werkzeuge und systematische Vorgehensweisen entwickelt, die nachweislich nicht nur zu einer Verringerung des Material- und Energieverbrauches in einzelnen Phasen des Lebenszyklus fuehren, sondern vor allem zur Nachhaltigkeit der Nutzung, insbesondere zur Lebensdauerverlaengerung von Gebaeuden bzw. zur Nutzungsdauerverlaengerung einzelner Elemente des technischen Sachsystems Gebaeude, angewendet werden koennen.

    This Operations, Maintenance, and Monitoring Report (OMMR) presents the findings, observations, and results from operation of the air sparging (AS) interim measure (IM) for Hot Spot (HS) Areas 1, 2, and 5 at the Converter Compressor Building (CCB) located at Kennedy Space Center (KSC), Florida. The objective of the IM at CCB HS Areas 1, 2, and 5 is to decrease concentrations of volatile organic compounds (VOCs) in groundwater in the treatment zones via AS to levels that will enable a transition to a monitored natural attenuation (MNA) phase. This OMMR presents system operations and maintenance (O&M) information and performance monitoring results since full-scale O&M began in June 2014 (2 months after initial system startup in April 2014), including quarterly performance monitoring events in July and October 2014 and January and May 2015. Based on the results to date, the AS system is operating as designed and is meeting the performance criteria and IM objective. The performance monitoring network is adequately constructed for assessment of IM performance at CCB HS Areas 1, 2, and 5. At the March 2014 KSC Remediation Team (KSCRT) Meeting, team consensus was reached for the design prepared for expansion of the system to treat the HS 4 area, and at the November 2014 KSCRT Meeting, team consensus was reached that HS 3 was adequately delineated horizontally and vertically and for selection of AS for the remedial approach for HS 3. At the July 2015 KSCRT meeting, team consensus was reached to continue IM operations in all zones until HSs 3 and 4 is operational, once HS 3 and 4 zones are operational discontinue operations in HS 1, 2, and 5 zones where concentrations are less than GCTLs to observe whether rebounding conditions occur. Team consensus was also reached to continue quarterly performance monitoring to determine whether operational zones achieve GCTLs and to continue annual IGWM of CCB-MW0012, CCBMW0013, and CCB-MW0056, located south of the treatment area.

  1. A cost driven predictive maintenance policy for structural airframe maintenance

    Directory of Open Access Journals (Sweden)

    Yiwei WANG

    2017-06-01

    Full Text Available Airframe maintenance is traditionally performed at scheduled maintenance stops. The decision to repair a fuselage panel is based on a fixed crack size threshold, which allows to ensure the aircraft safety until the next scheduled maintenance stop. With progress in sensor technology and data processing techniques, structural health monitoring (SHM systems are increasingly being considered in the aviation industry. SHM systems track the aircraft health state continuously, leading to the possibility of planning maintenance based on an actual state of aircraft rather than on a fixed schedule. This paper builds upon a model-based prognostics framework that the authors developed in their previous work, which couples the Extended Kalman filter (EKF with a first-order perturbation (FOP method. By using the information given by this prognostics method, a novel cost driven predictive maintenance (CDPM policy is proposed, which ensures the aircraft safety while minimizing the maintenance cost. The proposed policy is formally derived based on the trade-off between probabilities of occurrence of scheduled and unscheduled maintenance. A numerical case study simulating the maintenance process of an entire fleet of aircrafts is implemented. Under the condition of assuring the same safety level, the CDPM is compared in terms of cost with two other maintenance policies: scheduled maintenance and threshold based SHM maintenance. The comparison results show CDPM could lead to significant cost savings.

    Few studies evaluate whether short-term intervention effects are maintained over time for families caring for persons with dementia. This article examines whether treatment effects found at 6 months following active treatment were sustained at 12 months for 127 family caregivers who participated in an occupational therapy intervention tested as part of the National Institutes of Health Resources for Enhancing Alzheimer's Caregiver Health (REACH) initiative. A randomized two-group design was implemented with three assessment points: baseline, 6 months, and 12 months. Caregivers were randomly assigned to a usual care control group or intervention that consisted of six occupational therapy sessions to help families modify the environment to support daily function of the person with dementia and reduce caregiver burden. Following 6-month active treatment, a maintenance phase consisted of one home and three brief telephone sessions to reinforce strategy use and obtain closure. Non-inferiority statistical analysis was used to evaluate whether intervention caregivers maintained treatment benefits from 6 to 12 months in comparison to controls. For the sample of 127 at 6 months, caregivers in intervention reported improved skills (p = .028), less need for help providing assistance (p = .043), and fewer behavioral occurrences (p = .019) compared to caregivers in control. At 12 months, caregiver affect improved (p = .033), and there was a trend for maintenance of skills and reduced behavioral occurrences, but not for other outcome measures. An in-home skills training program helps sustain caregiver affect for those enrolled for more than 1 year. More frequent professional contact and ongoing skills training may be necessary to maintain other clinically important outcomes such as reduced upset with behaviors.

    The main goal of periodontal therapy is to establish an oral environment compatible with periodontal health by the physical disruption of the plaque biofilm and adjunctive chemical means if required. Implicit in this objective is the ongoing requirement of detection and interception of new and recurrent disease, which continues at selected intervals for the life of the dentition after the initial ("active") phase of periodontal treatment. This concept of ongoing periodontal maintenance therapy has been embraced as the mandatory requirement for favourable periodontal outcomes based on institutional clinical trials and in practice-based studies in various parts of the world. This review examines the ramifications of periodontal maintenance therapy based upon a multi-level assessment of logistic issues and risk factors at three levels: (1) The patient level - treatment time; patient attendance compliance; and homecare measures, antiseptics/antibiotics and smoking. (2) The level of the individual tooth - tooth loss; and evaluation of success versus survival. (3) The level of each tooth surface ("site") - probing depth, loss of attachment and bleeding on probing; and changes in clinical attachment levels. In spite of the diversity of studies conducted, there is agreement on the efficacy of periodontal maintenance therapy when compared with studies on untreated populations and in treated cases that were not maintained.

    ALMA is an interferometer composed of 66 independent systems, with specific maintenance requirements for each subsystem. To optimize the observation time and reduce downtime maintenance, requirements are very demanding. One subsystem with high maintenance efforts is cryogenics and vacuum. To organize the maintenance, the Cryogenic and Vacuum department is using and implementing different tools. These are monitoring and problem reporting systems and CMMS. This leads to different maintenance approaches: Preventive Maintenance, Corrective Maintenance and Condition Based Maintenance. In order to coordinate activities with other departments the preventive maintenance schedule is kept as flexible as systems allow. To cope with unavoidable failures, the team has to be prepared to work under any condition with the spares on time. Computerized maintenance management system (CMMS) will help to manage inventory control for reliable spare part handling, the correct record of work orders and traceability of maintenance activities. For an optimized approach the department is currently evaluating where preventive or condition based maintenance applies to comply with the individual system demand. Considering the change from maintenance contracts to in-house maintenance will help to minimize costs and increase availability of parts. Due to increased number of system and tasks the cryo team needs to grow. Training of all staff members is mandatory, in depth knowledge must be built up by doing complex maintenance activities in the Cryo group, use of advanced computerized metrology systems.

    The establishment of maintenance strategies is of crucial significance for the reliability of a plant and the economic efficiency of maintenance measures. Knowledge about the condition of components and plants from the technical and business management point of view therefore becomes one of the fundamental questions and the key to efficient management and maintenance. A new way to determine the maintenance strategy can be called: Knowledge Based Maintenance. A simple method for determining strategies while taking the technical condition of the components of the production process into account to the greatest possible degree which can be shown. A software with an algorithm for Knowledge Based Maintenance leads the user during complex work to the determination of maintenance strategies for this complex plant components. (orig.)

    Highlights: • Various remote maintenance schemes for DEMO were comparatively assessed based on requirements for DEMO remote maintenance. • The banana shape segment transport using all vertical maintenance ports would be more probable DEMO reactor maintenance scheme. • The key engineering issues are in-vessel transferring mechanism of segment, pipe connection and conducting shell design for plasma vertical stability. - Abstract: Maintenance schemes are one of the critical issues in DEMO design, significantly affecting the configuration of in-vessel components, the size of toroidal field (TF) coil, the arrangement of poloidal field (PF) coils, reactor building, hot cell and so forth. Therefore, the maintenance schemes should satisfy many design requirements and criteria to assure reliable and safe plant operation and to attain reasonable plant availability. The plant availability depends on reliability of remote maintenance scheme, inspection of pipe connection and plasma operation. In this paper, various remote maintenance schemes for DEMO were comparatively assessed based on requirements for DEMO remote maintenance. From the view points of the reliability of inspection on hot cell, TF coil size, stored energy of PF coil and portability of segment, the banana shape segment transport using all vertical maintenance ports would be more probable DEMO reactor maintenance scheme, and it has key engineering issues such as in-vessel transferring mechanism of segment, pipe connection and conducting shell design for plasma vertical stability.

Low productivity, downtime, and poor machine performance is often linked to inadequate plant maintenance, which in turn can lead to reduced production levels, increasing costs, lost market opportunities, and lower profits. These pressures have given firms worldwide the motivation to explore and embrace proactive maintenance strategies over the traditional reactive firefighting methods. The traditional view of maintenance has shifted into one of an overall view that encompasses Overall Equipment Efficiency, Stakeholders Management and Life Cycle assessment. From practical point of view it requires changes in approach to maintenance represented by managers and changes in actions performed within maintenance area. Managers have to understand that maintenance is not only about repairs and conservations of machines and devices, but also actions striving for more efficient resources management and care for safety and health of employees. The purpose of the work is to present strategic analysis based on SWOT analysis to identify the opportunities and strengths of maintenance process, to benefit from them as much as possible, as well as to identify weaknesses and threats, so that they could be eliminated or minimized.

    Maintenance work will be carried out on the CERN mobile network infrastructure (GSM) on the 23 and 24 July from 6 p.m. to 6 a.m. in order to replace discontinued equipment and to increase the bandwidth capacity of the GSM mobile network. All CERN GSM emitters (40 units) will be moved one by one to the new infrastructure during the maintenance. The call of a user connected to an emitter at the time of its maintenance will be cut off. However, the general overlapping of the GSM radio coverage should mean that users are able immediately to call again should their call be interrupted. IT/CS/CS

    Safer, Daniel J

    2017-10-01

    The principle evidence that antidepressant medication (ADM) is an effective maintenance treatment for adults with major depressive disorder (MDD) is from placebo substitution trials. These trials enter responders from ADM efficacy trials into randomized, double-blind placebo-controlled (RDBPC) effectiveness trials to measure the rate of MDD relapse over time. However, other randomized maintenance trial methodologies merit consideration and comparison. A systematic review of ADM randomized maintenance trials included research reports from multiple databases. Relapse rate was the main effectiveness outcome assessed. Five ADM randomized maintenance methodologies for MDD responders are described and compared for outcome. These effectiveness trials include: placebo-substitution, ADM/placebo extension, ADM extension, ADM vs. psychotherapy, and treatment as usual. The placebo-substitution trials for those abruptly switched to placebo resulted in unusually high (46%) rates of relapse over 6-12months, twice the continuing ADM rate. These trials were characterized by selective screening, high attrition, an anxious anticipation of a switch to placebo, and a risk of drug withdrawal symptoms. Selectively screened ADM efficacy responders who entered into 4-12month extension trials experienced relapse rates averaging ~10% with a low attrition rate. Non-industry sponsored randomized trials of adults with multiple prior MDD episodes who were treated with ADM maintenance for 1-2years experienced relapse rates averaging 40%. Placebo substitution trial methodology represents only one approach to assess ADM maintenance. Antidepressant maintenance research for adults with MDD should be evaluated for industry sponsorship, attrition, the impact of the switch to placebo, and major relapse differences in MDD subpopulations.

  17. Handbook of energy use for building construction

    Energy Technology Data Exchange (ETDEWEB)

    Stein, R.G.; Stein, C.; Buckley, M.; Green, M.

    1980-03-01

    The construction industry accounts for over 11.14% of the total energy consumed in the US annually. This represents the equivalent energy value of 1 1/4 billion barrels of oil. Within the construction industry, new building construction accounts for 5.19% of national annual energy consumption. The remaining 5.95% is distributed among new nonbuilding construction (highways, ralroads, dams, bridges, etc.), building maintenance construction, and nonbuilding maintenance construction. The handbook focuses on new building construction; however, some information for the other parts of the construction industry is also included. The handbook provides building designers with information to determine the energy required for buildings construction and evaluates the energy required for alternative materials, assemblies, and methods. The handbook is also applicable to large-scale planning and policy determination in that it provides the means to estimate the energy required to carry out major building programs.

    Lam, K C

    2006-09-01

    Readers are recommended to make good use of the concepts of "Failure Model Effects and Criticality Analysis" as discussed above. These should provide a more comprehensive study of reliability and availability of building services. The assessment methodology presented in this article is to a certain extent subjective. It is considered that a more quantitative and comprehensive study based on reliability and availability data from similar hospitals over recent years will help the analysis. Building services maintenance involves risk. Risks must be assessed before a design is fully implemented. The risks associated with building services installation have to be assessed at all stages, from concept to dismantling and disposal. This will ensure that risks are acceptable and manageable within the parameters defined by the overall cost and engineering requirements, statutory obligations and good practice.

    Full Text Available Given challenging competition of today service providers are required to be more proactive in satisfying the environmental conditions and customer needs. Proactive maintenance should start at the design stage with establishing the functions, functional failures and failure modes. The understanding the failure behavior, especially the relationship between potential failures, functional failures and diagnostic parameters is the most important task. In the next step the designer have to explore the maintenance activities as they have to apply to the design criteria. The models and frameworks have been presented in the paper also a comprehensive review of literature and some results of laboratory investigations.

  8. Maintenance in sustainable manufacturing

    Directory of Open Access Journals (Sweden)

    Vladimir Stuchly

    2014-09-01

    Full Text Available Background: Sustainable development is about reaching a balance between economic, social, and environmental goals, as well as people's participation in the planning process in order to gain their input and support. For a company, sustainable development means adoption of such business strategy and actions that contribute to satisfying present needs of company and stakeholders, as well as simultaneous protection, maintenance and strengthening of human and environmental potential which will be needed in the future. This new approach forces manufacturing companies to change their previous management paradigms. New management paradigm should include new issues and develop innovative methods, practices and technologies striving for solving problem of shortages of resources, softening environment overload and enabling development of environment-friendly lifecycle of products. Hence, its realization requires updating existing production models as they are based on previously accepted paradigm of unlimited resources and unlimited regeneration capabilities. Maintenance plays a crucial role because of its impact on availability, reliability, quality and life cycle cost, thus it should be one of the main pillars of new business running model.  Material and methods: The following paper is a result of research on the literature and observation of practices undertaken by a company within maintenance area. Results and conclusions: The main message is that considering sustainable manufacturing requires considerable expanding range of analysis and focusing on supporting processes. Maintenance offers numerous opportunities of decreasing influence of business processes on natural environment and more efficient resources utilization. The goal of maintenance processes realizing sustainable development strategy is increased profitability of exploitation and optimization of total lifecycle cost without disturbing safety and environmental issues.

    One of the major concerns of any maintenance organization is to understand and estimate the cost of maintenance releases of software systems. Planning the next release so as to maximize the increase in functionality and the improvement in quality are vital to successful maintenance management. The objective of this paper is to present the results of a case study in which an incremental approach was used to better understand the effort distribution of releases and build a predictive effort model for software maintenance releases. This study was conducted in the Flight Dynamics Division (FDD) of NASA Goddard Space Flight Center(GSFC). This paper presents three main results: 1) a predictive effort model developed for the FDD's software maintenance release process; 2) measurement-based lessons learned about the maintenance process in the FDD; and 3) a set of lessons learned about the establishment of a measurement-based software maintenance improvement program. In addition, this study provides insights and guidelines for obtaining similar results in other maintenance organizations.

  18. Accessibility of Radio Frequency Identification Technology in Facilities Maintenance

    Directory of Open Access Journals (Sweden)

    Chien-Ho Ko

    2017-01-01

    Full Text Available Replacing old buildings with new structures is an expensive proposition, but the service life of existing buildings can be extended by improving facilities maintenance. In particular, effective use of information technology can improve facilities maintenance and reduce maintenance costs. In recent years, some scholars have begun to apply Radio Frequency Identification (RFID technology to facilities maintenance. The present study examines the effective reading range for RFID applications within the context of facilities maintenance, where such applications can provide advantages including automatic reading and encoding of equipment, rapid reading and encoding of tag information, and tag-based data storage. However, the reading range of RFID tags can be limited by the presence of water vapor, electrical appliances, and metal surfaces. Through practical onsite testing, the study examines how effective reading range is impacted by dust, water, metal surfaces and electrical equipment, along with various reading and writing angles. Experimental results show that the presence of dust and water both have insignificant impacts on RFID signal reading. However, metal surfaces were found to have a significant negative effect on signal reading and RFID tags should be kept an appropriate distance from such materials. The results of this study can be taken as reference for the use of RFID in facilities maintenance and management.

    Full Text Available Although the maintenance-free building may be a theoretical possibility, all buildings are subject to the vagaries of defects, failures, deterioration and variation. The examples of these problems are fungus growth, peeling paint, termite attack, dampness, defective rainwater goods, roof defects, harmful growth, settlement, foundation failure, roof collapse and others. There are a great number of building defects and failures arose and being reported officially by mass media, especially problems with educational buildings. Theoretically, all buildings tend to deteriorate over period of time due to aging or other factors, regardless the types of buildings. There are several main factors can be taken into account such as design fault, poor maintenance, poor workmanship, building age and location of building. This paper will discuss on distinctive structural and non-structural building defects and failures than frequently happened in educational buildings. This paper is noteworthy to render varies of problems generally faced by Malaysian educational buildings to the public. As such, the awareness among them can be raised or improved. Furthermore, the public will concern, especially the government authorities should emphasize the laws and regulations to enforce the safety of construction work as well as the procedure in giving approval to the occupation of educational buildings.

    Road sector development policy in Bangka Belitung emphasis on equitable development, which is opening up new areas for industrial development zones of potential marine and coastal tourism, so that having an impact on the budget priority to build a new road. This led to a minimal budget provided for the maintenance of the existing road. This study aimed to evaluate the condition of the pavement both functionally and structurally, the growth of traffic density and the availability of existing road maintenance costs. Then, to analyze the influence of existing road conditions, traffic density and road maintenance costs to the type of road maintenance management. The results are compared with the results of the existing maintenance conducted by the Public Works Department of Bangka Belitung province. Evaluation of pavement conditions consists of visual assessment of pavement condition using IRI, pavement condition assessment functionally with deflection method using test data tool Benkelman Beam (BB) and the actual traffic load. IRI value, deflections and traffic growth gained from years 2011-2015 subsequently created regression models to obtain the relationship and the correlation coefficient. The analysis showed that using the same relative magnitude of the budget from 2011 to 2015, giving priority to the maintenance of the road with good conditions capable of providing the road with a steady state of 100%. Recommendations can be given that maintain the road with good conditions reflecting that preservation provide maximum results with the more efficient maintenance cost.

    In Chicago, Illinois, on May 7, 2009, a group of 53 medical educators representing many U.S. certification boards, residency review committees, and medical societies met to review and approve a white paper intended to promote Recommendation 4.2 of the Institute of Medicine report of April 14, 2008, "Retooling for an Aging America: Building the Healthcare Workforce." This recommendation is one of 14 and states: "All licensure, certification and maintenance of certification for healthcare professionals should include demonstration of competence in care of older adults as a criterion." Background information given included the growing numbers of older adults, review of a 15-year initiative by a section of the American Geriatrics Society (AGS) to include geriatric education in all surgical and some related medical specialties, a recent announcement of 26 elder care competencies to be expected of graduating medical students from association of American Medical Colleges (AAMC) affiliated schools, and the American Board of Medical Specialties (ABMS) approach to 'Reinforcing Geriatric Competencies through Licensure and Certification Examinations." Nine points involved in the implementation of this recommendation received discussion, and approaches to realization were presented. In conclusion, this white paper, which those listed as being in attendance approved, proposes hat all ABMS member boards whose diplomates participate in the care of older adults select the floor competencies enumerated by the AAMC that apply to their specialty and add or subtract those completed during their trainees' initial (intern) year and then define those needed in subsequent years of residency and ultimate practice. This would fulfill the requirements of Recommendation 4.2 above.

    Probably one of the most overlooked profit centers in industrial management strategy is savings in energy costs. Every $1 in certified energy savings is often worth over $10 in increased sales. The author has found from actual practice that there is big corporate profit in a shrewd, diligent steam trap management program. He describes a way to restructure corporate handling of trap maintenance to turn it into a source of revenue. Cited is a case history of building an intensive trap maintenance program at a large, 4000 trap chemical plant. The previously {open_quotes}good{close_quotes} maintenance program which was losing $565,000 per year in steam was turned into a $485,000 per year cost savings. This article will also give the steps that can in as few as 3 months generate over $125,000 annually in tax-free cash per 1000 traps with an investment payback of 18 months or less. The author is a businessman and energy management consultant that has no trap sales or promotion.

    2017-10-01

    The most effective building materials account for the highest growth not only in construction of residential and public buildings, but also other capital projects including roadways, bridges, drainage, communications and other engineering projects. Advancement in the technology of more efficient and ecologically responsible insulation materials have been a priority for safety, minimal maintenance and longevity of finished construction projects. The practical use of modern building materials such as insulation, sound reduction and low energy consumption are a benefit in cost and application compared to the use of outdated heavier and labor-intensive materials. The most efficient way for maximizing insolation and sound proofing should be done during the design stages of the project according to existing codes and regulations that are required by Western Government. All methods and materials that are used need to be optimized in order to reach a high durability and low operational and maintenance cost exceeding more than 50 years of the life of the building, whether it is for public, industrial or residential use. Western construction techniques and technologies need to be applied and adapted by the Russian Federation to insure the most productive successful methods are being implemented. The issues of efficient insulation materials are outlined in this article.

    ENGLISH ABSTRACT: Production systems have undergone dramatic changes in recent years. Many companies have implemented new technologies such as flexible manufacturing systems. There is therefore a shift in focus to maintenance and the effective management thereof. Maintenance is a dynamic activity and is comprised of a large number of interacting variables. An effective maintenance organisation is required to control these variables .
    This paper discusses the building of a maintenance organisation and the aspects that should be considered during the design. The way in which five companies that operate hot rolling mills apptoached the problem of building an effective maintenance organisation was investigated.

    This paper discusses the necessary changes to be implemented on the hardware side of the DCSP database. DCSP is currently tracking hardware maintenance costs in six separate databases. The goal is to develop a system that combines all data and works off a single database. Some of the tasks that will be discussed in this paper include adding the capability for report generation, creating a help package and preparing a users guide, testing the executable file, and populating the new database with data taken from the old database. A brief description of the basic process used in developing the system will also be discussed. Conclusions about the future of the database and the delivery of the final product are then addressed, based on research and the desired use of the system.

    Energy Technology Data Exchange (ETDEWEB)

    Soederberg, David; Weisbach, Henrik (Vattenfall Vindkraft AB, Stockholm (Sweden))

    2008-11-15

    This report aims to provide information of, and experiences from, service and maintenance of Lillgrund Offshore Wind Farm. The report deals with operation and maintenance (O and M) during construction, commissioning and the first three months of operation. Focus has been to describe the organization and cooperation between Vattenfall and Siemens. Experiences have been collected by interviews with representatives from Siemens and Vattenfall. The O and M strategy defined by Lillgrund's service and maintenance contract are based on a gradual take over of O and M. Siemens will be responsible for maintenance of Lillgrund during the first five years. During this five-year period, Vattenfall will build up its own maintenance organization for Lillgrund. The first three years, Vattenfall's technicians are supposed to form 30 % of the total number of maintenance technicians. The fourth and fifth year, the corresponding amount should be 50 %. During daytime, Lillgrund is operated locally. During nights and weekends, it is operated remotely by Vattenfall's operating centre in Esbjerg. The major O and M experience from Lillgrund is the need for good administrative and technical information systems. These systems should be implemented as soon as possible because of the large amounts of documentation that are created during the commissioning phase. The technical information systems must be able to present historic data of measurements in order to see trends and analyse faults

  1. Robots for Aircraft Maintenance

    Science.gov (United States)

    1993-01-01

    Marshall Space Flight Center charged USBI (now Pratt & Whitney) with the task of developing an advanced stripping system based on hydroblasting to strip paint and thermal protection material from Space Shuttle solid rocket boosters. A robot, mounted on a transportable platform, controls the waterjet angle, water pressure and flow rate. This technology, now known as ARMS, has found commercial applications in the removal of coatings from jet engine components. The system is significantly faster than manual procedures and uses only minimal labor. Because the amount of "substrate" lost is minimal, the life of the component is extended. The need for toxic chemicals is reduced, as is waste disposal and human protection equipment. Users of the ARMS work cell include Delta Air Lines and the Air Force, which later contracted with USBI for development of a Large Aircraft Paint Stripping system (LARPS). LARPS' advantages are similar to ARMS, and it has enormous potential in military and civil aircraft maintenance. The technology may also be adapted to aircraft painting, aircraft inspection techniques and paint stripping of large objects like ships and railcars.

  2. Weight maintenance: what's missing?

    Science.gov (United States)

    Hill, James O; Thompson, Helen; Wyatt, Holly

    2005-05-01

    Obesity has reached epidemic proportions in the United States, but there are few proven strategies for either preventing further weight gain or producing permanent weight loss. Our first priority should be to prevent the gradual weight gain experienced by much of the population. Although this will require less behavior change than producing and maintaining weight loss, helping Americans make and sustain the behavior changes needed to prevent gradual weight increases will be challenging. Because approximately 65% of Americans are already overweight or obese, we must also develop effective strategies to help achieve and maintain an amount of weight loss that improves their health and quality of life. Our real challenge is not in helping people lose weight but in helping them keep it off. Many programs have been shown to produce weight loss but few, if any, have been successful in maintenance of weight loss. Our challenge is in understanding how to help people keep off the weight they can lose in several ways.

    2017-08-15

    In this study, we present case studies to explore the dynamics of implementation and maintenance of health interventions. We analyze how specific interventions are built and eroded, how the building and erosion mechanisms are interconnected, and why we can see significantly different erosion rates across otherwise similar organizations. We use multiple comparative obesity prevention case studies to provide empirical information on the mechanisms of interest, and use qualitative systems modeling to integrate our evolving understanding into an internally consistent and transparent theory of the phenomenon. Our preliminary results identify reinforcing feedback mechanisms, including design of organizational processes, motivation of stakeholders, and communication among stakeholders, which influence implementation and maintenance of intervention components. Over time, these feedback mechanisms may drive a wedge between otherwise similar organizations, leading to distinct configurations of implementation and maintenance processes.

  9. Development of plant maintenance management system (pmms): a case study

    Che Azhar, N. A.; Mansor, M. A.

    2013-12-01

    In large plant industry, it is not easy to maintain machine performance without using any method such as checklist system. Manual checklist is a common maintenance checklist used in industry. All machine, equipment and parts that need to be checked will be written down for the employee to do maintenance checks. Converting the manual checklist to the Plant Maintenance Management System (PMMS) can improve the way of employees work and make plant management easier. Therefore, a new system was designed to maintain the equipment so that the activities are more efficient and cost effective. The system consists of three frames that connect to each other. The frames divide to section, equipment and checklist. This system also builds to prevent data from arbitrarily changes. Only certain officers or staffs are permitted to make modifications to data. Using this system, a company can make the office environment a paperless environment.

  10. TECHNICAL MAINTENANCE EFFICIENCY OF THE AIRCRAFT MAINTENANCE-FREE ON-BOARD SYSTEM BETWEEN SCHEDULED MAINTENANCES

    Directory of Open Access Journals (Sweden)

    A. M. Bronnikov

    2017-01-01

    Full Text Available The avionics concept of the maintenance-free on-board equipment implies the absence of necessity to maintain onboard systems between scheduled maintenance, preserving the required operational and technical characteristics; it should be achieved by automatic diagnosis of the technical condition and the application of active means of ensuring a failsafe design, allowing to change the structure of the system to maintain its functions in case of failure. It is supposed that such equipment will reduce substantially and in the limit eliminate traditional maintenance of aircraft between scheduled maintenance, ensuring maximum readiness for use, along with improving safety. The paper proposes a methodology for evaluating the efficiency of maintenance-free between scheduled maintenance aircraft system with homogeneous redundancy. The excessive redundant elements allow the system to accumulate failures which are repaired during the routine maintenance. If the number of failures of any reserve is approaching a critical value, the recovery of the on-board system (elimination of all failures is carried out between scheduled maintenance by conducting rescue and recovery operations. It is believed that service work leads to the elimination of all failures and completely updates the on-board system. The process of system operational status changes is described with the discrete-continuous model in the flight time. The average losses in the sorties and the average cost of operation are used as integrated efficiency indicators of system operation. For example, the evaluation of the operation efficiency of formalized on-board system with homogeneous redundancy demonstrates the efficiency of the proposed methodology and the possibility of its use while analyzing the efficiency of the maintenance-free operation equipment between scheduled periods. As well as a comparative analysis of maintenance-free operation efficiency of the on-board system with excessive

    Fowler, Kimberly M.; Rauch, Emily M.; Henderson, Jordan W.; Kora, Angela R.

    2010-06-01

    2nd report on the performance of GSA's sustainably designed buildings. The purpose of this study was to provide an overview of measured whole building performance as it compares to GSA and industry baselines. The PNNL research team found the data analysis illuminated strengths and weaknesses of individual buildings as well as the portfolio of buildings. This section includes summary data, observations that cross multiple performance metrics, discussion of lessons learned from this research, and opportunities for future research. The summary of annual data for each of the performance metrics is provided in Table 25. The data represent 1 year of measurements and are not associated with any specific design features or strategies. Where available, multiple years of data were examined and there were minimal significant differences between the years. Individually focused post occupancy evaluation (POEs) would allow for more detailed analysis of the buildings. Examining building performance over multiple years could potentially offer a useful diagnostic tool for identifying building operations that are in need of operational changes. Investigating what the connection is between the building performance and the design intent would offer potential design guidance and possible insight into building operation strategies. The 'aggregate operating cost' metric used in this study represents the costs that were available for developing a comparative industry baseline for office buildings. The costs include water utilities, energy utilities, general maintenance, grounds maintenance, waste and recycling, and janitorial costs. Three of the buildings that cost more than the baseline in Figure 45 have higher maintenance costs than the baseline, and one has higher energy costs. Given the volume of data collected and analyzed for this study, the inevitable request is for a simple answer with respect to sustainably designed building performance. As previously stated

    A challenge for the ITER project is to manage the design of many systems being developed in parallel. In order to control the machine configuration and ensure proper design integration, the ITER project has implemented the so-called 'configuration management models' (CMMs), aimed at controlling and managing the machine systems' interfaces. Specific issues are raised for modelling the ITER remote maintenance system (IRMS). That system shall provide the mean to support the remote maintenance operations for in-vessel components, remote transfer of activated components between the vacuum vessel (VV) and the hot cell facility and remote repairing, refurbishing and/or processing operations in the hot cell facility. The IRMS are dynamic, constantly changing morphologies, working envelopes and locations within the plant. This raises the issue of how to integrate the dynamic nature of this equipment into the CMM required for design integration. This paper describes the design methodology that is being developed to address the specific nature of the IRMS in the building of the CMM and gives examples to demonstrate the benefits to be gained by adopting this approach.

    Smart building concept is an implementation of technology developed in the construction industry throughout the world. However, the implementation of this concept is still below expectations due to various obstacles such as higher initial cost than a conventional concept and existing regulation siding with the lowest cost in the tender process. This research aims to develop intelligent building concept using value engineering approach to obtain added value regarding quality, efficiency, and innovation. The research combined quantitative and qualitative approach using questionnaire survey and value engineering method to achieve the research objectives. The research output will show additional functions regarding technology innovation that may increase the value of a building. This study shows that smart building concept requires higher initial cost, but produces lower operational and maintenance costs. Furthermore, it also confirms that benefit-cost ratio on the smart building was much higher than a conventional building, that is 1.99 to 0.88.

  15. Shuttle Repair Tools Automate Vehicle Maintenance

    Science.gov (United States)

    2013-01-01

    Successfully building, flying, and maintaining the space shuttles was an immensely complex job that required a high level of detailed, precise engineering. After each shuttle landed, it entered a maintenance, repair, and overhaul (MRO) phase. Each system was thoroughly checked and tested, and worn or damaged parts replaced, before the shuttle was rolled out for its next mission. During the MRO period, workers needed to record exactly what needed replacing and why, as well as follow precise guidelines and procedures in making their repairs. That meant traceability, and with it lots of paperwork. In 2007, the number of reports generated during electrical system repairs was getting out of hand-placing among the top three systems in terms of paperwork volume. Repair specialists at Kennedy Space Center were unhappy spending so much time at a desk and so little time actually working on the shuttle. "Engineers weren't spending their time doing technical work," says Joseph Schuh, an electrical engineer at Kennedy. "Instead, they were busy with repetitive, time-consuming processes that, while important in their own right, provided a low return on time invested." The strain of such inefficiency was bad enough that slow electrical repairs jeopardized rollout on several occasions. Knowing there had to be a way to streamline operations, Kennedy asked Martin Belson, a project manager with 30 years experience as an aerospace contractor, to co-lead a team in developing software that would reduce the effort required to document shuttle repairs. The result was System Maintenance Automated Repair Tasks (SMART) software. SMART is a tool for aggregating and applying information on every aspect of repairs, from procedures and instructions to a vehicle s troubleshooting history. Drawing on that data, SMART largely automates the processes of generating repair instructions and post-repair paperwork. In the case of the space shuttle, this meant that SMART had 30 years worth of operations

    General Services Administration (GSA) has been a pioneer in using Smart Building technologies but it has yet to achieve the full benefits of an integrated, enterprise-wide Smart Building strategy. In July 2008, GSA developed an initial briefing memorandum that identified five actions for a Smart Buildings feasibility study: (1) Identify and cluster the major building systems under consideration for a Smart Buildings initiative; (2) Identify GSA priorities for these clusters; (3) Plan for future adoption of Smart Building strategies by identifying compatible hardware; (4) Develop a framework for implementing and testing Smart Building strategies and converged networks; and (5) Document relevant GSA and industry initiatives in this arena. Based on this briefing memorandum, PBS and FAS retained consultants from Lawrence Berkeley National Laboratory, Noblis, and the Building Intelligence Group to evaluate the potential for Smart Buildings within GSA, and to develop this report. The project has included extensive interviews with GSA staff (See Appendix A), a review of existing GSA standards and documents, and an examination of relevant GSA and industry initiatives. Based on interviews with GSA staff and a review of GSA standards and documents, the project team focused on four goals for evaluating how Smart Building technology can benefit GSA: (1) Achieve Energy Efficiency Mandates--Use Smart Building technology as a tool to meet EISA 2007 and EO 13423 goals for energy efficiency. (2) Enhance Property Management--Deploy enterprise tools for improved Operations and Maintenance (O&M) performance and verification. (3) Implement Network as the Fourth Utility--Utilize a converged broadband network to support Smart Building systems and provide GSA clients with connectivity for voice, data and video. (4) Enhance Safety and Security--Harmonize Physical Access Control Systems (PACS) with Smart Building Systems.

  18. Maintenance therapy in multiple myeloma

    Directory of Open Access Journals (Sweden)

    2009-08-01

    Full Text Available The treatment of multiple myeloma (MM has changed dramatically in the past twenty years with the introduction of high-dose therapy plus autologous stem-cell transplantation (ASCT in younger patients and, more recently, of three novel agents (thalidomide, bortezomib, and lenalidomide. When conventional chemotherapy was the only available possibility, complete responses (CR were very rare and the objective of maintenance was to prolong remission duration by continuing the same type of treatment that induced the initial response. With recent therapeutic improvements, CR achievement becomes a realistic goal that, in most cases, is significantly correlated with the outcome (1. Therefore, both the nature and the impact of maintenance therapy have changed. Maintenance therapy is based currently on novel agents, and its objective is not only to control the clone but also to further decrease the tumor burden and improve the quality of response. A number of randomized studies show a benefit from maintenance therapy with novel agents (until now, mostly thalidomide, at least in terms of response rate and progression-free survival (PFS. However, there is still a debate as concerns the impact on overall survival (OS and the optimal administration of maintenance therapy.

    Full Text Available Maintenance decision making becomes more and more a management concern. Some decades ago, maintenance was still often considered as an unavoidable side effect of production. The perception of maintenance has evolved considerably. One of the current issues is the maintenance concept, being the mix of maintenance interventions and the general framework for determining this mix. In this paper we describe a modular framework, called Knowledge Based Maintenance, for developing a customised maintenance concept. After describing the general framework and its decision support use, some case experiences are given. This experience covers some elements of the proposed framework.

    The topic of diverless maintenance will address subsea production facilities in this paper. The major factors that determine diverless maintainability are development economics, maintenance philosophy, subsea hardware design, subsea intervention hardware, and compatibility of subsea hardware and remote work capabilities. The opportunity for developing and implementing low cost diverless installable and maintenable subsea facilities exist. Designs, hardwares, and procedures exist althoughmany of these have been combined into powerful solutions. This paper addresses the issues that need to be considered and provides one set of solutions. There are a number of other solutions that can be combined in a different set to provide a parallel but different solution.

    As we move towards the 21st century, those Manufacturing Industries that survive, will have changed their "efficiency" focus away from the conventional wisdom of "efficient individual tasks", to focus on the "effectiveness of a total manufacturing process". This seemingly insignificant change of emphasis, (from task to process) must include "the integration of process plant maintenance into the production process". Manufacturing companies, which do not include an effective plant maintenance strategy into their business strategy, will not survive the business environment of the 21st Century.

    Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

  5. Sustainable Buildings: An Ever Evolving Target

    2011-02-01

    Full Text Available Environmental considerations have called for new developments in building technologies to bridge the gap between this need for lower impacts on the environment and ever increasing comfort. These developments were generally directed at the reduction of the energy consumption during operations. While this was indeed a mandatory first step, complete environmental life cycle analysis raises new questions. For instance, for a typical low thermal energy consumption building, the embodied energy of construction materials now becomes an important component of the environmental footprint. In addition, the usual practice in life cycle analysis now appears to call for some adaptation—due to variable parameters in time—to be implemented successfully in building analysis. These issues bring new challenges to reach the goal of integrated design, construction, commissioning, operation, maintenance, and decommissioning of sustainable buildings.

  8. Maintenance as a safety issue.

    Science.gov (United States)

    White, Jim

    2008-11-01

    Because safety is related to electrical power systems maintenance, it seems reasonable to assume there could be legal issues if maintenance is not performed. OSHA has not yet taken the stand that not performing maintenance as required by the manufacturer, NFPA 70B, or ANSI/NETA MTS-07 constitutes a willful violation. OSHA defines a willful citation as one where: "the employer knowingly commits with plain indifference to the law. The employer either knows that what he or she is doing constitutes a violation, or is aware that a hazardous condition existed and made no reasonable effort to eliminate it". However, NFPA 70E 2009 requires this maintenance, and OSHA has stated on its Web site that NFPA 70E is "a guide for meeting the requirements of the OSHA electrical regulations". In addition, federal courts have found that NFPA 70E is "standard industry practice." Once a company receives and accepts a willful citation, especially if received as the result of an accident investigation, its worker's compensation protection no longer shields it. One definition given by a trial attorney for a willful citation was that it is equal to negligent behavior. Be smart: Maintain that equipment and save yourself major problems, including unscheduled shutdowns and possible litigation.

    Full Text Available In essence, process of maintaining equipment is a support process, because it indirectly contributes to operational ability of the production process necessary for the supply chain of the new value. Taking into account increased levels of automatization and quality, this proces s becomes more and more significant and for some branches of industry, even crucial. Due to the fact that the quality of the entire process is more and more dependent on the maintenance process, these processes must be carefully designed and effectively im plemented. There are various techniques and approaches at our disposal, such as technical, logistical and intensive application of the information - communication technologies. This last approach is presented in this work. It begins with organizational goa ls, especially quality objectives. Then, maintenance processes and integrated information system structures are defined. Maintenance process quality and improvement processes are defined using a set of performances, with a special emphasis placed on effectiveness and quality economics. At the end of the work, information system for improving maintenance economics is structured. Besides theoretical analysis, work also presents results authors obtained analyzing food industry, metal processing industry an d building materials industry.

The maintenance process concludes aircraft technical states con- nected with the objective patterns of technical qualities changes of the aircraft as a maintenance object and organizational states which determine the subjective organization and planning process of aircraft using. The objective maintenance pro- cess is realized in Maintenance and Repair System which does not include maintenance organization and planning and is a set of related elements: aircraft, Maintenance and Repair measures, executors and documentation that sets rules of their interaction for maintaining of the aircraft reliability and readiness for flight. The aircraft organizational and technical states are considered, their characteristics and heuristic estimates of connection in knots and arcs of graphs and of aircraft organi- zational states during regular maintenance and at technical state failure are given. It is shown that in real conditions of air- craft maintenance, planned aircraft technical state control and maintenance control through it, is only defined by Mainte- nance and Repair conditions at a given Maintenance and Repair type and form structures, and correspondingly by setting principles of Maintenance and Repair work types to the execution, due to maintenance, by aircraft and all its units mainte- nance and reconstruction strategies. The realization of planned Maintenance and Repair process determines the one of the constant maintenance component. The proposed graphical models allow to reveal quantitative correlations between graph knots to improve maintenance processes by statistical research methods, what reduces manning, timetable and expenses for providing safe civil aviation aircraft maintenance.

    Full Text Available All assets necessarily suffer wear and tear during operation. Prognostics can assess the current health of a system and predict its remaining life based on features capturing the gradual degradation of its operational capabilities. Prognostics are critical to improve safety, plan successful work, schedule maintenance, and reduce maintenance costs and down time. Prognosis is a relatively new area but has become an important part of Condition‐based Maintenance (CBM of systems. As there are many prognostic techniques, usage must be attuned to particular applications. Broadly stated, prognostic methods are either data‐driven, rule based, or model‐based. Each approach has advantages and disadvantages; consequently, they are often combined in hybrid applications. A hybrid model can combine some or all model types; thus, more complete information can be gathered, leading to more accurate recognition of the fault state. This approach is especially relevant in systems where the maintainer and operator know some of the failure mechanisms, but the sheer complexity of the assets precludes the development of a complete model‐based approach. The paper addresses the process of data aggregation into a contextual awareness hybrid model to get RUL values within logical confidence intervals so that the life cycle of assets can be managed and optimised.

  1. The impact of green building approach to office property value

    2017-12-01

    A real estate development often produces negative impacts towards the environment such as the reduction of the ecological capacity in the site and its surroundings, energy exploitation, and excessive pollutant emission. To overcome these issues, the green building concept or approach has been adapted by several real estate businesses in Indonesia especially in the office sector. According to the data provided by GBCI in 2017, there are 17 buildings listed as a certified green building office in various levels. As what has been known, the green building approach results in the increase of price in the planning, construction and the building's maintenance. This paper will discuss about the research results regarding the effect of the green building approach towards the property value of office buildings especially in Jakarta. The research will be executed through the comparison method, which is the process of comparing office building that have already adapted the green building concept with the one that have not, or in other words, the conventional office buildings. Data gathering is done through observation and interviews with developers and building managers. The research results show that by adapting the green building approach for office buildings in Jakarta, the property value regarding the utility, scarcity, effective demands, and transferability aspect can increase.

    Although lifestyle interventions have shown to be effective in reducing the risk for type 2 diabetes mellitus, maintenance of achieved results is difficult, as participants often experience relapse after the intervention has ended. This paper describes the systematic development of a maintenance programme for the extensive SLIMMER intervention, an existing diabetes prevention intervention for high-risk individuals, implemented in a real-life setting in the Netherlands. The maintenance programme was developed using the Intervention Mapping protocol. Programme development was informed by a literature study supplemented by various focus group discussions and feedback from implementers of the extensive SLIMMER intervention. The maintenance programme was designed to sustain a healthy diet and physical activity pattern by targeting knowledge, attitudes, subjective norms and perceived behavioural control of the SLIMMER participants. Practical applications were clustered into nine programme components, including sports clinics at local sports clubs, a concluding meeting with the physiotherapist and dietician, and a return session with the physiotherapist, dietician and physical activity group. Manuals were developed for the implementers and included a detailed time table and step-by-step instructions on how to implement the maintenance programme. The Intervention Mapping protocol provided a useful framework to systematically plan a maintenance programme for the extensive SLIMMER intervention. The study showed that planning a maintenance programme can build on existing implementation structures of the extensive programme. Future research is needed to determine to what extent the maintenance programme contributes to sustained effects in participants of lifestyle interventions.

    Full Text Available Building energy modeling (BEM, a subset of building information modeling (BIM, integrates energy analysis into the design, construction, and operation and maintenance of buildings. As there are various existing BEM tools available, there is a need to evaluate the utility of these tools in various phases of the building lifecycle. The goal of this research was to develop guidelines for evaluation and selection of BEM tools to be used in particular building lifecycle phases. The objectives of this research were to: (1 Evaluate existing BEM tools; (2 Illustrate the application of the three BEM tools; (3 Re-evaluate the three BEM tools; and (4 Develop guidelines for evaluation, selection and application of BEM tools in the design, construction and operation/maintenance phases of buildings. Twelve BEM tools were initially evaluated using four criteria: interoperability, usability, available inputs, and available outputs. Each of the top three BEM tools selected based on this initial evaluation was used in a case study to simulate and evaluate energy usage, daylighting performance, and natural ventilation for two academic buildings (LEED-certified and non-LEED-certified. The results of the case study were used to re-evaluate the three BEM tools using the initial criteria with addition of the two new criteria (speed and accuracy, and to develop guidelines for evaluating and selecting BEM tools to analyze building energy performance. The major contribution of this research is the development of these guidelines that can help potential BEM users to identify the most appropriate BEM tool for application in particular building lifecycle phases.

A significant portion of a facility's recurring annual expenses are associated with routine, long-term surveillance and maintenance (S&M) activities. However, ongoing S&M activities do nothing to reduce risks and basically spend money that could be reallocated towards facility deactivation. This paper discusses the background around DOE efforts to reduce surveillance and maintenance costs, one approach used to perform cost reviews, lessons learned from field implementation and what assistance is available to assist DOE sites in performing these evaluations.

    Dhakal, Dipesh; Sohng, Jae Kyung

    2015-11-03

    Nocardia spp. are aerobic, Gram-positive, catalase-positive, non-motile actinomycetes. Various species of the genus Nocardia have attracted attention due to their detrimental effects on human health. Recent discoveries, however, have exposed their importance as producers of bioactive compounds and degraders of complex organic compounds, as well as their involvement in biotransformation into valuable products. This unit includes general protocols for the laboratory maintenance of Nocardia spp., including growth in liquid medium, growth on solid agar, and long-term storage. Nocardia sp. CS682 (KCTC11297BP), isolated from soil collected in Jeonnam, Korea, is used as a prototype for explaining the considerations for efficient laboratory maintenance of Nocardia spp. Copyright © 2015 John Wiley & Sons, Inc.

    2015-04-01

    Full Text Available In the case of a high-valuable asset, the Operation and Maintenance (O&M phase requires heavy charges and more efforts than the installation (construction phase, because it has long usage life and any accident of an asset during this period causes catastrophic damage to an industry. Recently, with the advent of emerging Information Communication Technologies (ICTs, we can get the visibility of asset status information during its usage period. It gives us new challenging issues for improving the efficiency of asset operations. One issue is to implement the Condition-Based Maintenance (CBM approach that makes a diagnosis of the asset status based on wire or wireless monitored data, predicts the assets abnormality, and executes suitable maintenance actions such as repair and replacement before serious problems happen. In this study, we have addressed several aspects of CBM approach: definition, related international standards, procedure, and techniques with the introduction of some relevant case studies that we have carried out.

    2010-01-01

    To investigate the influence of maintenance spray on resin bonding to dentin. The crown of extracted, caries-free human molars was transversally sectioned with a model trimmer to prepare the dentin surfaces from mid-coronal sound dentin, and then uniformly abraded with #600 silicon carbide paper. The dentin surfaces were randomly divided into three groups: oil-free spray group where maintenance cleaner for air bearing handpieces was sprayed onto the dentin surface for 1 s and rinsed with water spray for 30 s; oil-containing spray group where maintenance cleaner for micro motor handpieces was sprayed onto the dentin surface for 1 s and rinsed with water spray for 30 s; and control group where the surface was rinsed with water spray for 30 s and then air-dried. These surfaces were then bonded with Clearfil SE Bond (Kuraray Medical), and resin composite (Clearfil AP-X, Kuraray Medical) build-up crowns were incrementally constructed on the bonded surfaces. After storage for 24 h in 37°C water, the bonded teeth were sectioned into hour-glass shaped slices (0.7-mm thick) perpendicular to the bonded surfaces. The specimens were then subjected to microtensile bond strength (μTBS) testing at a crosshead speed of 1.0 mm/min. Data were analyzed with one-way ANOVA and the Tukey-Kramer test. Maintenance spray-contaminated specimens (oil-free and oil-containing spray groups) showed significantly lower μTBS than control specimens (P contaminated groups (P > 0.05). Maintenance spray significantly reduces the bond strength of Clearfil SE Bond to dentin.

The building systems may be derived from functional requirements on buildings such as usability...... and security on highest level with sub-systems definitions on lever levels. Building functional sub-systems may be defined for user comfort, indoor-climate, evacuation, space configuration, aesthetics, O&M etc. These building systems are supported by Information and Communication Technology, ICT, and building...... component systems that are accessed and integrated in the real world of building use in different contexts. The ICT systems may be physically or virtually embedded in the building. Already in 1982 AT&T established the 'intelligent buildings', IB, concept due to marketing reasons and the Informart building...

  10. Lean thinking for a maintenance process

    2015-01-01

    Full Text Available The maintenance process shares significant operating costs in an organisation. Lean thinking can be incorporated into maintenance activities through applying its principles and practices/tools. Lean maintenance (LM is a prerequisite for lean manufacturing systems. This research proposes a new structure for LM process based on a systematic literature review of a significant number of related articles that were published on LM. The process structure is designed based on the five lean principles to guide and support organisations to pursue maintenance excellence. This study establishes a scheme for LM tools that are structured into 2 level 4 bundles and 26 lean practices/tools and develops a House of Waste (HoW to demonstrate the association between maintenance wastes and the LM tools. With a successful accomplishment of the proposed scheme, the performance of a maintenance department can create more improvement opportunities over time to reach the maintenance excellence status.

  11. Upgrade Opportunities for Buildings in City Centres

    Directory of Open Access Journals (Sweden)

    Silva M.

    2012-10-01

    Full Text Available This proposal focus on the potential of the existing buildings upgrade process in achieving the 20-20-20 goals, as these are the biggest energy consumers, the most significant built area and the better placed buildings within our cities. These buildings frequently lack basic maintenance and need intervention, but include within themselves a vast amount of incorporated energy and centuries of construction knowledge. Beyond the advantages that may result from re-attracting people back into the city centre, upgrading these existing buildings can also have positive bounce-back effect on the reduction of the energy needs related to transportation, as demonstrated in studies that alert to the impact of the building sprawl in the total energy use. As “buildings account for 40 % of total energy consumption in the Union”, the better performance of this sector has a significant role, remembering that “these requirements shall take account of general indoor climate conditions, in order to avoid possible negative effects such as inadequate ventilation, as well as local conditions and the designated function and the age of the building” [1]. The importance of “upgrading” the existing buildings resides on the fact that new buildings represent only approximately 1 or 2% of the total usable area, an estimate that is bound to decrease due to the current construction crisis. While the recent buildings tend to be more efficient, the numerous existing buildings are important stakeholders due to their massive consumptions and incorporated energy. The ongoing Annex 56 on “Energy & Greenhouse Gas Optimized Building Renovation” assumes that “Current standards do not respond effectively to the numerous constraints imposed by existing buildings and in many cases, the requirements result in very expensive measures and complex procedures, seldom accepted by occupants, owners or developers. It is then urgent for the new standards to respond to these

  3. Infrared Scanning For Electrical Maintenance

    Science.gov (United States)

    Eisenbath, Steven E.

    1983-03-01

    Given the technological age that we have now entered, the purpose of this paper is to relate how infrared scanning can be used for an electrical preventative maintenance program. An infrared scanner is able to produce an image because objects give off infrared radiation in relationship to their temperature. Most electrical problems will show up as an increase in temperature, thereby making the infrared scanner a useful preventative maintenance tool. Because of the sensitivity of most of the scanners, .1 to .2 of a degree, virtually all electrical problems can be pinpointed long before they become a costly failure. One of the early uses of infrared scanning was to check the power company's electrical distribution system. Most of this was performed via aircraft or truck mounted scanning devices which necessitated its semi-permanent mounting. With the advent of small hand held infrared imagers, along with more portability of the larger systems, infrared scanning has gained more popularity in checking electrical distribution systems. But the distribution systems are now a scaled down model, mainly the in-plant electrical systems. By in-plant, I mean any distribution of electricity; once it leaves the power company's grid. This can be in a hospital, retail outlet, warehouse or manufacturing facility.

  4. Carnitine in maintenance hemodialysis patients.

    Science.gov (United States)

    Guarnieri, Gianfranco

    2015-03-01

    Carnitine is a conditionally essential metabolite that plays a critical role in cell physiology. Carnitine is necessary for fatty acid transport to sites of beta-oxidation in the mitochondria, where it also helps to prevent organic acid accumulation. Because of these key regulatory functions, carnitine represents a crucial determinant of mitochondrial energy metabolism, whose deficiency may lead to metabolic and clinical disturbances. Loss of carnitine through dialytic membranes occurs in maintenance hemodialysis, resulting in potential carnitine depletion and relative increments of esterified carnitine forms. Carnitine supplementation has been reported to counteract some of these alterations and has been associated with some clinical benefits, such as enhanced response to erythropoietin as well as improvement in exercise tolerance, intradialytic symptom, hyperparathyroidism, insulin resistance, inflammatory and oxidant status, protein balance, lipid profile, cardiac function, and quality of life. Carnitine supplementation has an attractive theoretical rationale; however, there are no definitive supportive studies and conclusive evidence that L-carnitine supplementation in maintenance hemodialysis patients could improve these conditions. A trial of carnitine administration could be attempted for 6 to 12 months only in selected patients on dialysis who do not adequately respond to standard therapies, in the presence of symptomatology, and in conjunction with patient dialysis age and documented L-carnitine deficiency.

    2003-10-01

    Full Text Available Ontologies are continuously confronted to evolution problem. Due to the complexity of the changes to be made, a maintenance process, at least a semi-automatic one, is more and more necessary to facilitate this task and to ensure its reliability. In this paper, we propose a maintenance ontology model for a domain, whose originality is to be language independent and based on a sequence of text processing in order to extract highly related terms from corpus. Initially, we deploy the document classification technique using GRAMEXCO to generate classes of texts segments having a similar information type and identify their shared lexicon, agreed as highly related to a unique topic. This technique allows a first general and robust exploration of the corpus. Further, we apply the Latent Semantic Indexing method to extract from this shared lexicon, the most associated terms that has to be seriously considered by an expert to eventually confirm their relevance and thus updating the current ontology. Finally, we show how the complementarity between these two techniques, based on cognitive foundation, constitutes a powerful refinement process.

  6. Estimating Maintenance Cost for Web Applications

    2016-01-01

    Full Text Available The current paper tackles the issue of determining a method for estimating maintenance costs for web applications. The current state of research in the field of web application maintenance is summarized and leading theories and results are highlighted. The cost of web maintenance is determined by the number of man-hours invested in maintenance tasks. Web maintenance tasks are categorized into content maintenance and technical maintenance. Research is centered on analyzing technical maintenance tasks. The research hypothesis is formulated on the assumption that the number of man-hours invested in maintenance tasks can be assessed based on the web application’s user interaction level, complexity and content update effort. Data regarding the costs of maintenance tasks is collected from 24 maintenance projects implemented by a web development company that tackles a wide area of web applications. Homogeneity and diversity of collected data is submitted for debate by presenting a sample of the data and depicting the overall size and comprehensive nature of the entire dataset. A set of metrics dedicated to estimating maintenance costs in web applications is defined based on conclusions formulated by analyzing the collected data and the theories and practices dominating the current state of research. Metrics are validated with regards to the initial research hypothesis. Research hypothesis are validated and conclusions are formulated on the topic of estimating the maintenance cost of web applications. The limits of the research process which represented the basis for the current paper are enunciated. Future research topics are submitted for debate.

    THESAURUS allows the user to build a thesaurus or to subset into highly-specialized `mini-thesauri` the Energy Data Base (EDB) Subject Thesaurus, which contains the standard vocabulary of indexing terms (descriptors) developed and structured by the Office of Scientific and Technical Information (OSTI) for the building and maintenance of the U.S. Department of Energy (DOE) energy information databases. Thesaurus terms and their relationships including broader terms, narrower terms, related terms, use for and see also relationships, definitions, and scope notes may be entered. Entire word blocks may be copied from the OSTI primary Energy Thesaurus, from another mini-thesaurus, or both, and subsequently modified through the addition of new terms, the deletion of existing terms, and changes to the internal relationships among the word blocks within the mini-thesaurus to create a new, special-purpose thesaurus. THESAURUS also provides the ability to copy the entire Thesaurus allowing one to examine the effects of major changes to the thesaurus structure without having to modify the primary Thesaurus. It also supports creating sub-sets of the primary thesaurus, based on subject areas or other criteria. An interactive user with access to the TeX and PostScript proprietary software can produce the thesaurus in publication format. Once the thesaurus has been published, periodic supplements may be generated based on date of entry or change maintained by the Thesaurus software.

    2001-01-01

    The Maintenance Manager Working Group was established in order to revise existing maintenance contracts and to provide comprehensive and applicable tools for the execution of maintenance activities in the ST Division. This was necessary mainly due to the fact that the maintenance plans in the Division have often evolved rather than being consciously set up and in respect to the change towards result orientated contracts. Also, because the decrease of CERN staff and the trend towards outsourcing, a tighter and well-organised maintenance management has to be established. In order to achieve the most realistic and applicable results the technical and commercial aspects must be considered by following the industrial approach. This document will outline the objectives of the working group and will show the progress that has been made by the implementation of already achieved results. Furthermore this paper will show a possible structure of future maintenance management.

  1. Knowledge elicitation techniques and application to nuclear plant maintenance

    Science.gov (United States)

    Doyle, E. Kevin

    The new millennium has brought with it the opportunity of global trade which in turn requires the utmost in efficiency from each individual industry. This includes the nuclear power industry, a point which was emphasized when the electrical generation industry began to be de regulated across North America the late 1990s and re-emphasized when the northeast power grid of North America collapsed in the summer of 2003. This dissertation deals with reducing the cost of the maintenance function of Candu nuclear power plants and initiating a strong link between universities and the Canadian nuclear industry. Various forms of RCM (reliability-centred maintenance) have been the tools of choice in industry for improving the maintenance function during the last 20 years. In this project, pilot studies, conducted at Bruce Power between 1999 and 2005, and reported on in this dissertation, lay out a path to implement statistical improvements as the next step after RCM in reducing the cost of the maintenance. Elicitation protocols, designed for the age group being elicited, address the much-documented issue of a lack of data. Clear, graphical, inferential statistical interfaces are accentuated and developed to aid in building the teams required to implement the various methodologies and to help in achieving funding targets. Graphical analysis and Crow/AMSAA (army materials systems analysis activity) plots are developed and demonstrated from the point of view of justifying the expenditures of cost reduction efforts. This dissertation ultimately speaks to the great opportunity being presented by this approach at this time: of capturing the baby-boom generation's huge pool of knowledge before those people retire. It is expected that the protocols and procedures referenced here will have applicability across the many disciplines where collecting expert information from a similar age group is required.

    2006-06-01

    Hundreds of mirror segment, thousands of high precision actuators, highly complex mechanical, hydraulic, electrical and other technology subsystems, and highly sophisticated control systems: an ELT system consists of millions of individual parts and components, each of them may fail and lead to a partial or complete system breakdown. The traditional maintenance concepts characterized by predefined preventive maintenance activities and rigid schedules are not suitable for handling this large number of potential failures and malfunctions and the extreme maintenance workload. New maintenance strategies have to be found suitable to increase reliability while reducing the cost of needless maintenance services. The Reliability Centred Maintenance (RCM) methodology is already used extensively by airlines, and in industrial and marine facilities and even by scientific institutions like NASA. Its application increases the operational reliability while reducing the cost of unnecessary maintenance activities and is certainly also a solution for current and future ELT facilities. RCM is a concept of developing a maintenance scheme based on the reliability of the various components of a system by using "feedback loops between instrument / system performance monitoring and preventive/corrective maintenance cycles." Ideally RCM has to be designed within a system and should be located in the requirement definition, the preliminary and final design phases of new equipment and complicated systems. However, under certain conditions, an implementation of RCM into the maintenance management strategy of already existing astronomical infrastructure facilities is also possible. This presentation outlines the principles of the RCM methodology, explains the advantages, and highlights necessary changes in the observatory development, operation and maintenance philosophies. Presently, it is the right time to implement RCM into current and future ELT projects and to save up to 50% maintenance

The dentin surfaces were randomly divided into three groups: oil-free spray group where maintenance cleaner for air bearing handpieces was sprayed onto the dentin surface for 1 s and rinsed with water spray for 30 s; oil-containing spray group where maintenance cleaner for micro motor handpieces was sprayed onto the dentin surface for 1 s and rinsed with water spray for 30 s; and control group where the surface was rinsed with water spray for 30 s and then air-dried. These surfaces were then bonded with Clearfil SE Bond (Kuraray Medical, and resin composite (Clearfil AP-X, Kuraray Medical build-up crowns were incrementally constructed on the bonded surfaces. After storage for 24 h in 37°C water, the bonded teeth were sectioned into hour-glass shaped slices (0.7-mm thick perpendicular to the bonded surfaces. The specimens were then subjected to microtensile bond strength (μTBS testing at a crosshead speed of 1.0 mm/min. Data were analyzed with one-way ANOVA and the Tukey-Kramer test.Results: Maintenance spray-contaminated specimens (oil-free and oil-containing spray groups showed significantly lower μTBS than control specimens (P < 0.05.

    Microorganisms play a primary role in the etiology of periodontal disease. Inadequate or no treatment permits progressive destruction of the periodontium. Periodontal destruction can be prevented in the presence of some plaque and gingival inflammation provided there are efforts at oral hygiene and frequent prophylaxis. An optimal time interval for prophylaxis and instructions in oral hygiene, after periodontal therapy, appears to be 3 months. Ongoing repetitive instructions in oral hygiene appear to be the only way to achieve and maintain significantly increased levels of oral cleanliness. Two-week intervals between prophylaxis, if feasible, seem to provide superior maintenance for periodontal health after therapy. Similar intervals between prophylaxes in school children--again, if feasible--virtually eliminate gingivitis.

    This paper analyzes four generations of Maintenance Resource Management (MRM) programs implemented by aviation maintenance organizations in the United States. Data collected from over ten years of survey research and field observations are used for this analysis; they are presented in a case-study format. The first three generations of MRM programs were episodic efforts to increase safety through teamwork, focus group discussions, and awareness courses, respectively. Now, the fourth generation programs, characterized by a commitment to long-term communication and behavioral changes in maintenance, are set to build on those earlier generations, toward a culture of mutual trust between mechanics, their managers, and regulators.

    Buildings are an integral part of our nation’s energy economy. The advancement in information and communications technology (ICT) has revolutionized energy management in industrial facilities and large commercial buildings. As ICT costs decrease and capabilities increase, buildings automation and energy management features are transforming the small-medium commercial and residential buildings sectors. A vision of a connected world in which equipment and systems within buildings coordinate with each other to efficiently meet their owners’ and occupants’ needs, and where buildings regularly transact business with other buildings and service providers (such as gas and electric service providers) is emerging. However, while the technology to support this collaboration has been demonstrated at various degrees of maturity, the integration frameworks and ecosystems of products that support the ability to easily install, maintain, and evolve building systems and their equipment components are struggling to nurture the fledging business propositions of their proponents.

    Harris, Douglas H

    2008-06-01

    The author presents and discusses discoveries and developments contributing to enhanced electronics maintenance performance. This body of research is viewed from the vantage point of Nick Bond's 1970 Ely Award-winning article in Human Factors, "Some Persistent Myths About Military Electronics Maintenance." Bond identified a set of myths and summarized research that not only produced information and techniques leading to demonstrably improved maintenance performance but also exploded many unfounded beliefs that were commonly held before the research had been conducted and the findings disseminated. The period from 1964 through 1986, as reflected by publications in the journal, was a productive period of research that led to greater understanding of human factors in electronics maintenance and to numerous advances that contributed, ultimately, to more effective maintenance performance. Technological advances, combined with what we learned about maintenance performance, have substantially reduced the maintenance burden and enhanced the maintenance of electronic systems. Some of the principal lessons learned from this research on electronics maintenance apply to understanding the effects of equipment complexity, providing an optimal role for automation, designing more appropriate on-the-job training, and enhancing troubleshooting skills.

    Periodontal maintenance therapy is the most important stage of periodontal treatment, yet compliance is low. Overcoming the barriers associated with the low compliance involves a complex set of problems relating to the patient, the clinician and the interactions between them. It is therefore important to create a periodontal maintenance treatment programme which takes into consideration the needs of each individual patient. In addition, regional variations and differences in practice profiles are also factors to be accommodated in a maintenance programme. Good co-operation between the referring dentist and the specialist is required when recommendations are made to the patient regarding maintenance therapy.

    The aim of this paper is to present an application of 6D building information modelling (6D BIM) on a real business-storage building in Slovenia. First, features of building maintenance in general are described according to the current Slovenian legislation, and also a general principle of BIM is given. After that, step-by-step activities for modelling 6D BIM are exposed, namely from Element list for maintenance, determination of their lifetime and service measures, cost analysing and time analysing to 6D BIM modelling. The presented 6D BIM model is designed in a unique way in which cost analysis is performed as 5D BIM model with linked data to use BIM Construction Project Management Software (Vico Office), integrated with 3D BIM model, whereas time analysis as 4D BIM model is carried out as non-linked data with the help of Excel (without connection to 3D BIM model). The paper is intended to serve as a guide to the building owners to prepare 6D BIM and to provide an insight into the relevant dynamic information about intervals and costs for execution of maintenance works in the whole building lifecycle.

    This Research Update presents the status of the Existing Buildings Research program of the Office of Building Technologies of the US Department of Energy for the period 1989-199 1. This program covers research on energy efficiency improvements for the residential and commercial buildings in this country. ne Existing Buildings Research program has contributed to significant improvements in energy efficiency of existing buildings by development of improvements to retrofit technologies, by coordinating and conducting research studies on the use of energy efficiency technologies (to reduce barriers and increase use), and by continually evaluating changes in technologies that could improve and maintain buildings energy efficiency. If the energy efficiency of the buildings sector in this country is to be dramatically improved over the next 30 years, we must improve the use of energy efficiency technologies. Improved delivery of measures, improved understanding of how buildings actually perform in the field, and methods for improving operations and maintenance of buildings and energy equipment are all examples of ways to improve the deployment (transfer) of technologies. Much has been learned about technology deployment in buildings in the first five years of the program, and our future plans will be directed at continuing the improvements and making a real contribution to the energy efficiency future of the United States.

  6. Mine maintenance - the cost of operation

    Energy Technology Data Exchange (ETDEWEB)

    Kreilis, O.; Singleton, T. [Southern Engineering Services (Australia)

    1998-12-31

    Increasing world competition puts pressure on sales volumes and prices. This in turn reduces potential profit margins. This in turn increases the focus on costs. Increasing demands on quality and service puts pressure on delivery performance - the right product at the right time. This in turn reduces the scope for errors and delays - and this in turn increases focus on equipment reliability. In the mining industry, both costs and equipment reliability have one significant thing in common - they are driven substantially by maintenance. Maintenance, once the Cinderella of the boardroom is a pivotal function and demands management attention and, if managed well, can be a source of competitive advantage. They made the decision to put maintenance high on their agendas because they realised that good maintenance is a vital factor in achieving excellence. Maintenance, because of its impact on return on capital, is a key driver of performance. By reducing maintenance costs, companies can improve their performance. Top managers are increasingly recognising that maintenance is an area in which they must be involved. As Australian mining and metallurgical companies look to the year 2000 and beyond, maintenance will become an increasingly strategic function, capable of delivering sustainable competitive advantage to those companies that get it right. 7 refs., 5 figs.

    Full Text Available Although the topic of language maintenance has received considerable attention from linguists around the world, there are still many aspects of this language-contact phenomenon that could be examined further. This paper aims to contribute to the existing body of knowledge by exploring the state of Croatian as a heritage language in Canada. The aim of the paper is two-fold. The first is to describe the demographic characteristics of the Croatian community by investigating the number of people of Croatian descent and the number of Croatian speakers in Canada. The second, and more specific, aim of the paper is to provide an account of the state of Croatian as a minority language and examine the extent of language maintenance in the community. To accomplish the first objective, Canadian census data (1996, 2001, 2006, and 2011 was analyzed, with special focus on linguistic census data (number and age of Croatian speakers in Canada, mother tongue of people of Croatian descent, language most used at home, etc.. To accomplish the second objective, census data was supplemented with data from a questionnaire-based survey completed by members of the Croatian community in Toronto. The survey was completed by 220 participants; 110 first-generation Croatian Canadians and 110 second-generation Croatian Canadians. Two versions of the questionnaire were designed, one for first-generation participants and the other for second-generation participants. The great majority of items in the two versions were identical; each version contained questions about demographic characteristics, language use in everyday life, and self-perceived language proficiency in English and Croatian. The majority of questions were of a closed type (multiple-choice questions and rating scales, but there were also some open-ended questions, so as to give participants the opportunity to express their viewpoint or comment on certain issues. Questions were written in both Croatian and English

  10. [Contact lens care and maintenance].

    Science.gov (United States)

    Bloise, L

    2017-04-01

    All contact lenses with replacement schedules longer than daily must be maintained. At each step of their use, the lenses may be contaminated. Contact lens solutions perform the essential functions of cleaning, decontaminating and preserving the lenses to prevent infectious problems and improve wearing comfort. Contact lens contamination essentially comes from hands, cleaning solutions, cases, water and the environment. The pathogenic microorganisms are mainly Gram-negative bacteria, fungi and amoebae. Contact lens deposits may or may not have an organic origin. Their presence increases the risk of infection because they serve as a nutrient matrix for microbes, and they are responsible for wearing discomfort. Contact lens solutions differ in their composition, their mechanism of action and the concentration of the various agents. To prescribe the best lens care system to each wearer and for each material, it is necessary to be very familiar with them. Maintenance is the main cause of discomfort with contact lenses, either through improper use, solution-material incompatibility, or a reaction of the wearer to the components.

    2015-02-01

    Full Text Available Background: Robotic vehicles such as straddle carriers represent a popular form of cargo handling amongst container terminal operators.Objectives: The purpose of this industry-driven study is to model preventative maintenance (PM influences on the operational effectiveness of straddle carriers.Method: The study employs historical data consisting of 21 273 work orders covering a 27-month period. Two models are developed, both of which forecast influences of PM regimes for different types of carrier.Results: The findings of the study suggest that the reliability of the straddle fleet decreases with increased intervals of PM services. The study also finds that three factors – namely resources, number of new straddles, and the number of new lifting work centres – influence the performances of straddles.Conclusion: The authors argue that this collaborative research exercise makes a significant contribution to existing supply chain management literature, particularly in the area of operations efficiency. The study also serves as an avenue to enhance relevant management practice.

  13. Monitoring Building Systems for Schedule Compliance

    Energy Technology Data Exchange (ETDEWEB)

    Jensen, Andrew M.; Belew, Shan T.

    2013-02-19

    As Pacific Northwest National Laboratory (PNNL) initiated a Core Business Hours program, it became a challenge to ensure that the hundreds of systems campus wide were operating within their programmed schedules. Therefore, a collaborative exchange between PNNL operations and PNNL researchers developing the Decision Support for Operations and Maintenance (DSOM) software package was initiated to create a tool to solve this problem. This new DSOM tool verifies systems are operating within scheduled operation times by polling Building Automation and Control Network (BACnet) identifiers of systems’ on/off or command statuses. The tool records the time spent in operation state (ON) and totalizes each system over a rolling 7-day period, highlighting systems that are running over the scheduled hours. This snapshot view allows building management to look quickly at the entire campus to ensure that systems are not operating beyond their scheduled hours.

  14. Renewable Substitutability Index: Maximizing Renewable Resource Use in Buildings

    Directory of Open Access Journals (Sweden)

    Ravi S. Srinivasan

    2015-05-01

    Full Text Available In order to achieve a material and energy balance in buildings that is sustainable in the long run, there is an urgent need to assess the renewable and non-renewable resources used in the manufacturing process and to progressively replace non-renewable resources with renewables. Such progressive disinvestment in the non-renewable resources that may be substituted with renewable resources is referred to as “Renewable Substitutability” and if implemented, this process will lead to a paradigm shift in the way building materials are manufactured. This paper discusses the development of a Renewable Substitutability Index (RSI that is designed to maximize the use of renewable resources in a building and quantifies the substitution process using solar emergy (i.e., the solar equivalent joules required for any item. The RSI of a building or a building component, i.e., floor or wall systems, etc., is the ratio of the renewable resources used during construction, including replacement and maintenance, to the building’s maximum renewable emergy potential. RSI values range between 0 and 1.0. A higher RSI achieves a low-energy building strategy promoting a higher order of sustainability by optimizing the use of renewables over a building’s lifetime from formation-extraction-manufacturing to maintenance, operation, demolition, and recycle.

    1981-01-01

    An examination is made of the opportunities and alternatives for energy conservation where great savings are possible - the design, construction, and operation of buildings and industrial facilities. Contrasts are made between the actual energy requirements of various building types (office buildings, schools, hospitals, shopping centers) and results are described of recent energy conservation measures applied to existing buildings. Energy-saving options available in the design and construction of new buildings covered are: measures in planning on-site operations; energy-intensive construction materials; energy-saving methods in designing and constructing a building's exterior envelope; ways to conserve energy in interior building spaces. Basics of energy management methods in buildings and the various building-automation systems available are reviewed. Energy-saving opportunities in areas of maintenance, providing better training for and communications with operating personnel, using computers and microprocessors for load computations, energy analysis, and monitoring or control of various energy consuming systems are explored. Other topics covered are: power generation, including solar energy as a conservation strategy; energy use at the construction site; fuel-resource utilization; load management; on-site energy systems; and alternative options such as waste recycling and geothermal energy. A broad nationwide overview of energy policies and overall strategies, a historical review of industrial sector conservation opportunities, and the environmental impact of the various energy technologies are presented.

    Bamboo is considered as a sustainable material in the world of construction, and it is vastly available in Indonesia. The general utilization of the material is increasingly frequent, however, its usage as a deployable structure-a recently-developed use of bamboo, is still untapped. This paper presents a report on a deployable bamboo structure project, covering the entire building life-cycle phase. The cycle encompasses the designing; fabrication; transportation; construction; operation and maintenance; as well as a plan for future re-use. The building is made of a configuration of the structural module, each being a folding set of bars which could be reduced in size to fit into vehicles for easy transportation. Each structural module was made of Gigantochloa apus bamboo. The fabrication, transportation, and construction phase require by a minimum of three workers. The fabrication and construction phase require three hours and fifteen minutes respectively. The building is utilized as cafeteria stands, the operation and maintenance phase started since early March 2017. The maintenance plan is scheduled on a monthly basis, focusing on the inspection of the locking mechanism element and the entire structural integrity. The building is designed to allow disassembly process so that it is reusable in the future.

    The Building Design Advisor (BDA) is a software environment that supports the integrated use of multiple analysis and visualization tools throughout the building design process, from the initial, schematic design phases to the detailed specification of building components and systems. Based on a comprehensive design theory, the BDA uses an object-oriented representation of the building and its context, and acts as a data manager and process controller to allow building designers to quickly navigate through the multitude of descriptive and performance parameters addressed by the analysis and visualization tools linked to the BDA. Through the Browser the user can edit the values of input parameters and select any number of input and/or output parameters for display in the Decision Desktop. The Desktop allows building designers to compare multiple design alternatives with respect to any number of parameters addressed by the tools linked to the BDA.
