We consider the competing risks problem for a repairable unit which at each sojourn may be subject to either a critical failure, or a preventive maintenance (PM) action, where the latter will prevent the failure. It is reasonable to expect a dependence between the failure mechanism and the PM regime. The paper presents a new model, called the repair alert model, for handling such cases. This mo...

Consider the competing risks situation for a component which may be subject to either a failure or a preventive maintenance action, where the latter will prevent the failure. It is then reasonable to expect a dependence between the failure mechanism and the PM regime. The chapter reconsiders the so called repair alert model which is constructed for handling such cases. A main ingredient here is...

preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...

In industrial manufacturing, there are techniques that can identify certain risks in the processes cause inconsistencies operation of equipment, hazards for operator and waste. One supports engineering company Preventive Maintenance (PM) tasks focus their efforts on analyzing critical devices could degrade quality products obtained. Companies have an average system attention to machinery equipm...

Degradation of engineering systems is a phenomenon that affects the reliability and lifetime systems. Maintenance deteriorating has been widely studied over past 50 years. Numerous maintenance models have proposed in literature to manage degradation. In this paper, we focus on condition-based strategy for those suffering continuous deterioration process. We propose use non-constant threshold de...

Benefits In the past, preventive maintenance was performed without any guidance or regard for safety or cost concerns, as long as systems performed their functions. The primary reason for the development of RCM was to implement a preventive maintenance strategy that could adequately address system availability and safety at the lowest possible cost. The RCM process answers and directs preventiv...

Traditional scheduling problems with the batch processing machines (BPM) assume that machines are continuously available, and no time is needed for their preventive maintenance (PM). In this paper, we study a realistic variant of flowshop scheduling which integrates flow shop batch processing machines (FBPM) and preventive maintenance for minimizing the makespan. In order to tackle the given pr...
