摘要: 针对多资源约束下的串并联生产系统,在多资源约束条件下考虑系统的可用性,以各工序资源需求优先级为标准,建立了一种多目标动态维护模型.引入权重因子,通过采用可靠度恢复因子描述各工序设备维护前后可靠度的变化过程,建立以维护成本和系统可用度为优化目标的维护策略.通过仿真抽样求解出系统在给定区间内的预防性维护与机会维护阈值.结果表明,该维护策略能保证多资源约束下的串并联生产系统维护成本和系统可用度最优.

Abstract: Aiming at the series-parallel production system with multi-resource constraint, a multi-objective dynamic maintenance model is established by considering the availability of the system under multi-resource constraint and taking the priority of each process resource requirement as the standard. By introducing the weight factor and using the reliability recovery factor to describe the reliability change process before and after the maintenance of each process equipment, a maintenance strategy with the maintenance cost and system availability as the optimization objective was established. The preventive maintenance and opportunity maintenance thresholds of the system in a given interval are solved by simulation sampling. The results show that the maintenance strategy can guarantee the maintenance cost and system availability of the complex degraded production system under multi-resource constraints.

Key words: muliple resources constrained, series-parallel production system, multiple target, system availability, dynamic maintenance
