摘　　要：Petri网对具有并行、异步和随机时间的离散事件仿真系统具有很强的可视化描述能力,它可以通过标记在网内的流动揭示系统的动态行为。而直升机反潜过程是一个复杂的离散事件过程,包括了搜索、跟踪、定位和攻击四个阶段,各阶段之间的转换是由各种战术规则和随机战场态势所决定的,具有并行、异步和冲突竞争等特点,采用传统的排队论和决策树方法描述直升机反潜过程非常困难。在建立了描述这些过程的Petri网的基础上,提出了处理并行和竞争变迁的实施原则,实现了直升机反潜过程描述的可视化。Petri net has powerful ability when applied in visually describing parallel, asynchronous and stochastic discrete event simulation system. The system dynamic actions are described by means of tokes in the Petri net. The simulation of helicopter anti-submarine is a complicate discrete event procession which has four sections: searching, tracking, position and attacking. The transfer among those sections, which is parallel, asynchronous and stochastic, is decided by a variant of tactical rules and combat field posture. Its very difficult to describe the procession by traditional theory as queuing theory and decision theory. An extensive Petri net model has been established for the complicated discrete event simulation procession of helicopter anti-submarine. Based on the model, a firing principle is brought forward for dealing with parallel and competitive transition and visually describing the procession.
