面向任务T-Petri网的舰载机出动流程仿真

摘要

In order to know the takeoff process of carrier plane definitely and instruct its action better, the takeoff procedure simulation of carrier plane is researched. By analyzing the commonness about takeoff procedure and the strongpoint about Petri Net, a new task oriented model-T-Petri(Task-Petri)is proposed. T-Petri can simulate different takeoff task dynami-cally by extending its basic net simply. It simplifies takeoff procedure, satisfies the diversity modeling demands of takeoff task and avoided complexity of repeated modeling. T-Petri is used to simulate the carrier plane takeoff procedure of Kuznetsov aircraft carrier. And the Gantt chart about takeoff procedure is given, which shows the takeoff procedure distinctly. The takeoff time expression is proposed. By comparing the takeoff time given by takeoff time expression and T-Petri simu-lation respectively, the results show that T-Petri can be used to simulate takeoff procedure of carrier plane, and the simula-tion result is precise.%为明确舰载机的出动过程，以更好地指导舰载机操作，对舰载机出动流程仿真问题进行研究。在分析舰载机出动流程共性以及Petri网优点的基础上设计了一种面向任务的综合T-Petri（Task-Petri）网模型。该模型通过对基本网进行简单扩充便可以动态仿真不同的出动任务，不仅简化了出动流程，而且可以满足舰载机出动任务的多样性建模要求，避免了重复建模的复杂性。利用T-Petri网模型对库兹涅佐夫号航母舰载机出动流程进行仿真试验，并给出了甘特图，比较直观地给出了舰载机出动流程。分析给出了舰载机出动时间计算公式，将其所得的出动时间与通过T-Petri网仿真得出的出动时间进行比较，结果表明所提出的T-Petri网模型用于仿真舰载机出动流程是可行的，且结果比较精确。
