摘　　要：当系统中存在某些重要部件易损坏时,可以对其采取机会维修的策略。这不仅能提高可用度还能分摊固定维修费用,改善系统经济性。从此角度出发,提出了维修费用和可用度的计算表达式。之后考虑系统中单个部件进行机会维修下,研究了在使用更换维修时维修费用和可用度,并在蒙特卡罗方法基础上设计了仿真算法。结合实例表明本方法可以有效提高可用度并降低维修费用。When there is some critical parts susceptible to damage in the system,you can take opportunis-tic maintenance policy.Not only can it improve the availability but also share the fixed maintenance cost and improve the system economics.The calculation expression of maintenance cost and availability is put forward in this article from this view.Then design the simulation algorithm based on Monte Carlo method with single-part opportunistic maintenance policy and adopting replacement maintenance.This policy which can increase the availability and reduce the maintenance costs is verified by an example.
