仿真模型重用是当前仿真领域的热点问题,其在工程领域的实现能够极大提高开发效益。鉴于各类现代防空作战行动中的相似性,采用DEVS方法为其建立分层耦合的离散事件模型(DEM),在事件驱动层面对各类应用情景中的模型状态转移做了统一的、规范的描述,并针对不同的应用情景引入行为模型(BM)建模,在行为表示层面上描述模型状态转移的具体算法,最后设计了BM和DEM结合的动态链接方式,给出仿真程序组成示例,实现了从事件驱动层到行为表示层的模型重用。
Simulation model reuse is a hot issue in the field of simulation. Its implementation in engineering field can greatly improve development efficiency. In view of the similarities in all kinds of modern air defense operations, DEVS is used to establish a hierarchical coupled discrete event model (DEM), and a unified and normalized model state transition in event-driven layers is applied Describe and describe the behavioral model (BM) modeling for different application scenarios, and describe the specific algorithm of state transition in the aspect of behavioral representation. Finally, the dynamic link mode combining BM and DEM is designed, and the simulation program is given as an example to realize From the event-driven layer to the behavioral presentation layer model reuse.
