摘要
考虑带检测、预防性维修的冲击模型,在假设系统的故障不能修复如新的条件下,以降低系统运行成本为目标,以检测周期T、系统更换前故障次数N为联合决策变量,利用几何过程和更新过程理论建立了系统平均费用率C(T,N)的数学模型。最后,通过数值方法求得最优的检测更换策略。
Considering a shock model with inspection and preventive repair,and assuming that the repair of the system is not as good as new,the system average cost rate C(T,N) is obtained by using the geometric process and renewal process,where T is the time interval of inspections and N is the number of system failures before replacement.Finally,the optimal policy is derived by using the numerical method.
