Abstract

Developing an appropriate maintenance and spare parts inventory strategy is an effective means to ensure the safe and reliable operation of the system. Currently, the joint optimization research of maintenance and spare parts inventory strategy for multi-unit systems neglects the reuse of the unit after maintenance, which wastes maintenance resources and increases maintenance costs. In addition, in order to facilitate modeling and calculation, time parameters related to preventive maintenance are ignored, and the differentiated effects of preventive maintenance on different types of unit failures are also not considered, so the strategy developed is not accurate. In this paper, considering the differential effects of preventive maintenance on different types of unit failures, maintenance strategies at unit-level are formulated first. Then, the costs involved are analyzed, the joint optimization model of imperfect opportunistic maintenance based on dynamic time window and spare parts inventory for multi-unit system is established, which takes into account the time parameters related to preventive maintenance and the reuse of the unit after maintenance. Furthermore, the solution algorithm of the model is designed. Finally, a numerical example is provided to demonstrate the effectiveness and superiority of the proposed method.

考虑备件再利用的多单元系统不完全预防性机会维修与备件库存联合优化

制定适当的维护和备件库存策略是确保系统安全可靠运行的有效手段。目前，多机组系统维修与备件库存策略联合优化研究忽略了维修后机组的再利用，浪费了维修资源，增加了维修成本。此外，为了便于建模和计算，忽略了与预防性维修相关的时间参数，也没有考虑预防性维修对不同类型机组故障的差异化影响，因此所制定的策略不准确。考虑到预防性维修对不同类型机组故障的不同影响，本文首先制定了机组层面的维修策略。然后，分析了所涉及的成本，建立了考虑预防性维修相关时间参数和维修后机组重用性的多机组系统不完全机会性维修联合优化模型，该模型基于动态时间窗和备件库存。并设计了模型的求解算法。最后，通过数值算例验证了该方法的有效性和优越性。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
