导弹动力系统最佳预防维修周期的数字仿真

DIGITAL SIMULATION OF OPTIMUM PREVENTIVE MAINTENANCE CYCLE OF MISSILE POWER SYSTEM

导弹武器系统中有很多是多次使用的可修复杂系统。对于这种复杂系统，尤其是其寿命周期，预防维修时间及事后维修时间为离散分布时，其最佳预防维修周期难以用一般方法求得。针对这种情况，本文利用蒙特卡罗随机模拟法建立了系统计算模型，并通过模拟计算，得出了最佳预防维修周期的数字仿真结果。此结果可为制定导弹武器最佳修复策略提供依据。

There are many reusable repairable components in a missile weapon system. The optimum preventive maintenance cycle of these components usually can not be obtained with common ways, especially when the life cycle, preventive maintenance time and subsequent maintenance time present dispersed distribution. In view of this, this paper builds a system calculated model by Monte Carlo random simulation method, and gains digital simulation results of optimum preventive maintenance cycle through the simulation calculation. The results can be regarded as a basis to work out an optimum repair way for missile weapons.
