In this paper, we focus on a continuously deteriorating critical equipment which its failure cannot be measured by cost criterion. For these types of systems like military systems, nuclear systems, etc it is extremely important to avoid failure during the actual operation of the system. In this paper we propose an approach which constrains failure probability to a pre-specified value. This valu...

This study aims to select optimal maintenance strategy for components of an electric motor of the National Iranian Oil Refining and Distribution Company. In this regard, a method based on revised multi choice goal programming and analytic hierarchy process (AHP) is presented. Since improving the equipment reliability is an important issue, reliability centered maintenance (RCM) strategies are i...

In hazardous repair of a repairable system, there is a strong probability of further failure during a period immediately following the repair. To model failures of such systems under failure-based maintenance, a class of point process models is proposed in which the failure intensity is a function only of equipment age and of time since most recent repair. Cost modelling requires the computatio...
