武器装备效能仿真的可组合建模框架研究

武器装备效能仿真不同于一般的复杂系统仿真, 具备很大的组合建模潜力和迫切的组合仿真需求. 当前的统一仿真协议、统一建模方法、统一模型规范等组合仿真途径主要还是从技术角度出发的, 没有充分结合应用领域的实际, 难以真正实现组合仿真. 提出了基于模型框架实现组合仿真的思路, 通过将领域共性不变知识(DIK)固化为可组合的模型框架, 而应用可变知识(AVK)则可在模型框架基础上通过定制或扩展的方式进行描述. 设计了武器装备效能仿真的可组合建模框架(CMF), 应用实践表明能够明显地提高仿真开发效率, 有力地支持模型级可组合.

A composable modeling framework for weapon systems effectiveness simulation

Weapon systems effectiveness simulation (WESS) is a special kind of complex system simulation. There are not only much potential for composable modeling, but also urgent demands for composable simulation in WESS domain. Current approaches toward simulation composability e.g. unified simulation protocols, unified modeling methodologies, unified model specifications and so on, are mostly put forward from a technological perspective with lots of application domain specific knowledge left alone. Consequently, the true composability aim is far from fulfilled. In this research, the pivot of composability is put on the model architecture of a simulation application. By ways of pre-implementing the domain invariable knowledge (DIK) as a composable domain specific modeling framework, simulation application development is simplified as representing application variable knowledge (AVK) via customizing or extending the domain specific modeling framework. Along this approach, a composable modeling framework (CMF) for WESS domain is developed. The successful applications of CMF show its effectiveness on improving simulation development efficiency and model composability.
