针对串联系统建立了基于可靠性约束的预防性维修优化模型,该模型充分考虑到预防维修可以提高系统可靠性的同时,其故障率会随着维修次数的增加而上升,引入役龄回退因子对预防维修活动前后系统性能的动态变化进行了描述。通过实例验证了该优化模型的正确性与可用性,对模型作进一步的扩展,还可用于更一般复杂的串并联系统。
Based on the reliability constraints, a series of preventive maintenance optimization models are established for the tandem system. The model fully takes into account that preventive maintenance can improve the reliability of the system, and its failure rate will increase with the increase of maintenance times. The service age regression factor The dynamic changes of system performance before and after preventive maintenance activities are described. The correctness and usability of this optimization model are validated by examples. The model is further extended and can be applied to more general and complicated serial-parallel systems.
