Simulation-based Method for Computation Reliability and Optimum Quantity of N:K(m) Cross-Strapping Standby System

采用基于排队网络的仿真模型来描述(m)交叉储备系统，并给出了系统可靠度及备件最优储备量的仿真计算方法。本文的方法能适用于具有多个维修台的非马尔科夫型(m)交叉储备系统。各种算例检验了本文方法的适用性。文末用解析的方法和本文的方法计算了马尔科夫型(m)系统的可靠度及备件最优储备量，二者符合的很好。

：In this paper, a queue network based simulation model is applied to describing the (m) cross-strapping standby system. Algorithms for computation reliability and optimum quantity of (m) system are provided. Our approach is applicable to complex non-Markovian model of (m) system with multi-repairer. Finally, the reliability and optimum quantity of Markovian (m) system are calculated with both analytical method and our method, the two results fit well. Our research may be used as the basis for further study of the (m) system.
