Abstract: 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.

Key words: Phased Mission Systems(PMS), spare parts, Monte Carlo method
