基于Petri网的基层级多机种通用性维修保障设备优化配置

Optimal allocation of multi-aircraft universal support equipments based on Petri nets in grass-roots level

多机种战时的出动架次系统是一个复杂的离散事件系统,适合运用Petri网理论对其进行建模。本文运用Petri网理论构建多机种战时的出动架次模型,应用着色Petri网(coloured Petri nets,CPN)Tools软件仿真模拟基层级的维修保障过程,重点分析通用性维修保障设备的配置对多机种同场次出动架次率的影响,并以多机种的出动架次率为优化目标,获得通用性保障设备的最优配备比(保障设备数:飞机数),最后对影响多机种出动架次的因素进行敏感性分析。同时对优化配置模型进行了案例验证,可为作战部门进行保障设备数量的最优化配备提供有效的理论支持。

The sortie generation rate system is a complicated discrete event system. It is appropriate for Petri net theory to establish a model. This paper establishes the sortie generation rate model of multi-aircrafts in the wartime applying the Petri net theory, and it uses coloured Petri nets (CPN) Tools software to simulate the process of maintaining and supporting in the grass-roots level. Then, we lay special stress on the influence of the allocation of universal support equipments on the multi-aircraft sortie generation rate, and regard the multi-aircraft sortie generation rate as the optimal goal to obtain the most optimal allocation proportion of universal support equipments. The sensitivity of the influential factors of the multi-aircraft sortie generation rate is analysed, and a case is used to prove the optimal allocation model. In that case, the model can provide effective support for combat units to optimize the number of support equipments.
