针对可修系统在实际的运行过程中无法通过维修手段恢复如新的情况,通过考虑维修后故障率的直接减少建立了可修系统的不完全维修模型,以此描述可修系统维修改善的效果.在不完全维修模型的基础上,构建了系统的成本函数,得到了系统最优的预防性维修次数和预防性维修时间间隔.最后,通过实例验证了模型的可行性和有效性.
In view of the fact that the repairable system can not be restored as new during the actual operation by repairing means, an incomplete repair model of the repairable system is established by considering the direct reduction of the post-maintenance failure rate so as to describe the effect of repairable system maintenance and improvement Based on the incomplete maintenance model, the cost function of the system is constructed, and the optimal preventive maintenance times and preventive maintenance intervals are obtained.Finally, the feasibility and effectiveness of the model are verified through examples.
