General preventive maintenance model for the components of a system, which improves the reliability to ‘as good as new,’ was used to optimize the maintenance cost. The cost function of a maintenance policy was minimized under given availability constraint. On the other hand, in order to ensure appropriate reliability and availability, the development of the optimal maintenanc...

Bi-objective optimization of the availability allocation problem in a series–parallel system with repairable components is aimed in this paper. The two objectives of the problem are the availability of the system and the total cost of the system. Regarding the previous studies in series–parallel systems, the main contribution of this study is to expand the redundancy allocation problems to syst...

Availability and reliability of a manufacturing system are the most common indicators in the reliability engineering area to assess the quality and on-time deliveries of the products they produce. The purpose of this paper is to analyze the availability, reliability. failure metrics such as MTBF and MTTF, and also steady-state availability of a cooking oilproduction line using a Markov approach...

Habitats may become unavailable to fish in reservoirs at different water elevations. Coves are particularly vulnerable habitat loss, as these peripheral zones isolated from the main reservoir. Quantifying loss elevation reductions and estimating cost of replacing specific types or maintaining a target percentage total cover can help fisheries managers plan for restoration projects reservoirs. W...

As per ISO-10816, electric motors up to 15 kW are classified as Class I machines, and the major reason for their failure is that vibrations in them above alert limit. This study presents a new model predicting condition-based maintenance (CBM) initiation points through vibration measurement system of machines. The proposed follows accelerated life testing (ALT) procedure. ALT includes formation...
