基于HTCPN的飞机出动架次率仿真测算方法

A Simulation Measurement Method of Aircraft Sortie Rate Based on HTCPN

针对“热保障”条件下飞机出动架次率难以测算的问题,提出一种基于分层赋时着色Petri网(HTCPN)的飞机出动架次率仿真测算方法。首先,根据飞机基层级维修保障工作,建立飞机连续出动模型与保障流程;其次,运用Petri网理论和CPN tools软件,构建基于HTCPN的机务保障全过程计算机仿真模型;最后,通过算例分析找出制约飞机出动架次率的重要影响因素。结果表明,所提方法不仅能够找出影响飞机出动的重要因素,还能为飞机出动架次率测算提供技术支撑,具有一定工程应用价值。

To solve the problem that it is difficult to measure the aircraft sortie rate under the condition of“no engine stopping”,a simulation measurement method based on Hierarchical Timed Colored Petri Net(HTCPN)is proposed to measure the aircraft sortie rate.Firstly,based on the aircraft maintenance work at the grassroots level,a continuous sortie model and the maintenance process are established.Secondly,Petri net theory and CPN tools software are used to construct the computer simulation model of the whole process of maintenance support based on HTCPN.Finally,the key factors that restrict the sortie rate of aircraft are identified through an analysis of calculation cases.The results show that the proposed method can not only find out the key factors affecting aircraft sortie,but also provide technical support for the measurement of aircraft sortie rates,which has certain value in engineering applications.
