针对多阶段任务系统(PMS)的备件问题，构建基于Monte Carlo方法的仿真模型，给出具体的算法流程。该模型以多态结构函数为基本输入，产生等价于基本设备寿命实现值的随机数，代入仿真模型，经过逻辑运算和统计分析得到系统的可靠度，为多态PMS的备件决策提供依据。应用Matlab软件进行仿真实验分析，结果表明该方法具有较高的仿真精度。

Reliability Simulation Model for Multi-mode Phased Mission Systems Based on Spare Parts Scheme

Aiming at the spare parts of Phased Mission Systems(PMS), the simulation model is established based on the Monte Carlo method, and the detailed algorithm process is presented. The model is input with multi-mode structure function, generates the random sequence corresponding to the basic component life implementation value by using Monte Carlo method, and puts this sequence to the system stimulation model to get system reliability through logic operation and statistical analysis. Using the model, it can make a decision on the quantity of spare parts for PMS. An example by Matlab software shows the model is of highly simulation precision.
