Maintenance is essential in keeping wind energy assets operating efficiently. With the development of advanced condition monitoring, diagnostics and prognostics, condition-based maintenance has attracted much attention offshore industry recent years. This paper models various activities their impacts on degradation performance turbine components. An integrated strategy corrective maintenance, i...

The quality of products, maintenance operations, and transportation policies are primary concerns managers in inventory production planning issues. Besides that, environmental regulations growing increasingly attracted much attention to green concepts such as sustainable production. Previous authors conducted a wide range research on these problems separately. Regarding the gap an integrated fr...

Maintenance management has a direct influence on equipment reliability and safety. However, a large portion of traditional maintenance models and reliability analysis methods usually assumes that only perfect maintenance is performed on the system and the system will restore to as good as new regardless of the kind of preventive maintenance work-order that is performed. This is not practical in...

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...

The availability of a periodic inspection system under mixed maintenance policies is studied in this paper. To accommodate the characteristic multiple failure modes for complex systems, failures can be divided into two modes: hard and soft failure. When occurs, corresponding corrective will performed, taking random time perfect policy; contrast, if found, preventive imperfect policy. dynamic ag...

The study aims to provide a Bayesian statistical method with natural conjugate for facilities’ preventive maintenance scheduling related the hybrid competing failure mode. An effective strategy not only can improve system’s health condition but also increase efficiency, and therefore firm needs make an appropriate increasing utilization of system reasonable costs. In last decades, issues deteri...

This paper is to propose a two-stage preventive maintenance (PM) policy for the multi-state deterioration system under periodic inspection and with multiple candidate actions for PM. Such policy is mainly to schedule PM optimally and also on how to choose the action optimally for each PM. The scheduling includes two tasks: to determine after completing each PM when to make the decision and then...

Abstract: In recent decades, high profits of extended warranty have caused that third-party firms consider it as a lucrative after-sales service. However, customers division in terms of risk aversion and effect of offering extended warranty on manufacturers’ basic warranty should be investigated through adjusting such services. Since risk-averse customers welcome extended warranty, while the cu...
