摘　　要：分析各种维修方法的特点,剖析以可靠性为中心的维修(RCM)与其它维修方法之间的内在联系,给出设备维修评价指标体系。以广义维修成本最低为目标,以设备可用度为约束条件,以维修周期为优化变量,提出了以可靠性为中心的设备维修成本优化模型。采用蒙特卡洛仿真和遗传算法进行模型求解,实现维修周期和维修成本的优化,以一液压-机械复合传动系统为例,验证方法的有效性。We analyze the characteristics of various maintenance methods, expatiate on the internal relationship between reliability centered maintenance（RCM） and other maintenance methods and present maintenance evaluation indices. Taking generalized maintenance cost minimization as objective, equipment availability as constraint condition, and maintenance cycle as optimization variable, we establish the RCM optimization model and solve the model using the Monte Carlo simulation and genetic algorithm, thus optimizing maintence cost and cycle. The effectiveness of the RCM method is verified with a hydraulic-mechanical compound transmission system as an example.
