联邦对象模型与仿真对象模型开发过程建模

在基于高层体系结构(HLA)的分布仿真系统开发过程中,需要对仿真系统中的交互数据进行建模和抽象,以便生成FOM和SOM,保证联邦执行的正确运行。提出了综合开发联邦对象模型(FOM)和仿真对象模型(SOM)的七个步骤,并对各个步骤所完成的任务进行了详细的定义。这些步骤包括:对仿真任务中的实体和事件类型进行抽象和建模;分解仿真任务,确定联邦成员及其仿真的实体和事件类型;确定FOM中的对象类和交互类;生成SOM草案;综合SOM草案,生成FOM;确定FOM中的路由空间,生成正式的FOM;生成正式的SOM。

Modeling of FOM/SOM Development Process

In order to create FOM and SOM and insure federation executing correctly, interactive data in the simulation system should be abstracted and modeled when developing distributed simulation system under HLA protocol. A processing model of seven steps was proposed to develop FOM and SOM altogether. And the function of each step was defined in detail. Those steps are: abstract and modeling Entity and events styles from simulation mission, divide simulation mission into sub-mission for each federate and define entity and events styles for each federate, define object class and interaction class in FOM, create SOM draft, synthesize all SOMs into a FOM draft, define routine space and create a formal FOM, and at last step, create formal SOMs.
