“…In predictive maintenance, facilities are considered to deserve service attention only when direct evidence exists that deterioration has happened. This kind of maintenance is based on the need to perform maintenance only when the repair is really necessary, not after a specified period of time [12].…”

This study assessed the maintenance practices and quality improvements of public infrastructure by adopting the National Theatre of Ghana as a case study. This research specifically examined maintenance practices of the National Theatre, a national asset and the biggest auditorium used by the country to host major national events. A single case study design was employed for the study. Both questionnaires and interviews were used to obtain data from sampled staff and management of the National Theatre. The study revealed that the maintenance practices at the theatre are mostly routine involving cleaning, fumigation and servicing. There are also quarterly and annual maintenance schedules, but all these are predictive and preventive maintenance works. The maintenance works at the theatre have also ensured that the National Theatre is serene and habitable in the short term. The maintenance practices also help to maintain the aesthetics and attraction of the theatre in the medium term, and in the long term, maintenance practices can forestall the sudden breakdown of major equipment hence prevented the sudden collapse of the entire facility. However, the study found a gap between maintenance practices and quality maintenance practices at the National Theatre. The theatre has not integrated quality management practices, hence some of the important long-term benefits of maintenance practices have been missed and there is a backlog of maintenance that need to be worked out. Staff of the National theatre are not oblivious to the backlog of maintenance that the facility faced with but suggested that this is a result of inadequate budgetary allocation for maintenance. The study concludes that increasing budgetary appropriation for maintenance, there is a need to improve public cooperation and support for the National Theatre in order to improve the quality of the edifice.

“…One failure mode can lead to more than one consequence, including safety effect, environment effect, economic loss effect, and maintenance cost effect, which can be regarded as four types of risks. Based on the evaluation criteria of failure probability s , failure detectability s , and failure severity s , RPN of safety risk (12 th column), RPN of environmental risk (13 th column), RPN of economic loss risk (14 th column), and RPN of maintenance cost risk (15 th column) can be calculated by adopting the Probabilistic Risk Analysis (PRA) [17,18].…”

Asset Integrity Management (AIM) technology has been rapidly developed and applied so that it has become a main management technology of offshore platform equipment and facilities. Risk identification and quantitative evaluation method is one of the core contents in the AIM. However, most of the existing methods are qualitative analysis results, simple analysis process, and strong subjectivity, which can no longer meet the development of AIM technology system. By analyzing disadvantages and shortcomings of the existing methods and adapting to the technology requirements of the AIM, a Streamline Failure Mode Effects and Criticality Analysis (SFMECA) was presented to achieve risk identification and quantitative evaluation based on the traditional FMECA and Borda scoring method. Taking a truss crane as a case study, feasibility and operability of the SFMECA were verified effectively with obtaining a detailed and complete analysis worksheet. Compared with their analysis process and worksheet, it was more specific, more comprehensive, and more operable by applying the SFMECA than the traditional FMECA. Moreover, in the SFMECA, failure risk was divided into four categories in detail and quantified separately to better distinguish and evaluate failure effect. Then a comprehensive quantitative evaluation method of four risks was carried out and risk knots in risk priority number (RPN) were obviously reduced, which help to develop more accurate risk management measures. Independent evaluation mechanism of multiple experts or teams is adopted in the SFMECA to make the analysis and evaluation results more objective. So the worksheet obtained through the SFMECA contains more quantitative data, comprehensive information, and objective results, which can better meet technical system of the AIM. Therefore, application of the SFMECA can provide technical support for extension and application of the AIM technology, including risk quantitative analysis, maintenance decision, and integrity evaluation, for offshore platform equipment and facilities.

“…Unfortunately, this study only focuses on a case of maintenance of the rolling stock, in addition to not addressing the waste related to maintenance and consider a reduced number of lean tools. More recently, Irajpour et al [36] proposed a framework to determine the effectiveness of maintenance strategies based on lean thinking approach. The proposed approach is not based on any standard to define the characteristics of lean thinking as applied to maintenance and considers a little number of lean tools.…”

Lean Maintenance Applied to Improve Maintenance Efficiency in Thermoelectric Power Plants

Thermoelectric power plants consist of a set of critical equipment that require high levels of availability and reliability. Due to this, maintenance of these physical assets is gaining momentum in industry. Maintenance is considered as an activity that contributes to improving the availability, efficiency and productivity of each piece of equipment. Several techniques have been used to achieve greater efficiencies in maintenance, among which we can find the lean maintenance philosophy. Despite the wide diffusion of lean maintenance, there is no structured method that supports the prescription of lean tools applied to the maintenance function. This paper presents the experience gathered in two lean maintenance projects in thermoelectric power plants. The application of lean techniques was based on using a previously developed multicriterial decision making process that uses the Fuzzy Analytic Hierarchy Process (AHP) methodology to carry out a diagnosis and prescription tasks. That methodology allowed the prescription of the appropriated lean techniques to resolve the main deficiencies in maintenance function. The results of applying such lean tools show that important results can be obtained, making the maintenance function in thermoelectric power plants more efficient and lean.
