摘　　要：综合考虑任务要求、保障对象、保障系统三者之间的运行机理,建立了一种基于任务驱动的机群战备完好性仿真模型。以作战任务要求和机群技术状态为输入,进行O&MTA,建立逻辑确定而工期随机的PERT网络,分析PERT网络中各节点和路径上的维修时间、备件延误时间、资源组等待时间的分布函数和参数,然后用Monte Carlo仿真确定成为关键路径概率最高的路径为关键路径,最后用Monte Carlo方法对选定的关键路径进行计算,得出机群装备战备完好率随着保障时间的变化曲线。计算结果表明该仿真模型可以较好反映不同任务要求与保障系统下机群可用性的真实情况,为装备的作战使用提供较好的决策依据。In considering of the three relations among mission requirement, aircraft fleet and support system,a mission-driven aircraft fleet operational readiness simulation model is established. Using the op- erational mission requirements and aircraft fleet technical state as inputs, performing O＆MTA,the PERT network with logic certainty and stochastic schedule is set up. The distribution functions and parameters of maintenance time, spare parts delay time and resource group waiting time of the nodes and paths in the PERT network are analyzed. The most critical paths are found by using Monte Carlo method. By calculat- ing the selected critical paths, the change rate of the aircraft fleet readiness rate with the support time can be obtained. The results show that the simulation model can reflect the real situation of aircraft fleet oper- ational readiness rate under different mission requirement support for equipment operational use. and support system, and can provide decision
