基于MDA的HLA仿真开发方法

MDA-Based Simulation Development of HLA

为了解决HLA与其它中间件产品脱节、应用范围局限以及可重用的问题,将MDA方法引入HLA仿真设计中,尝试用MDA的模型思想提升HLA在整个软件生命周期内的可重用和互操作问题。通过将联邦成员的行为逻辑和集成代码分开,并用邦员的PIM映射行为逻辑,用SOM映射集成代码,建立PIM和SOM之间的对应关系并映射成接口代码,纵向条理化了联邦成员的开发,降低了联邦成员代码开发的复杂性和集成的难度。在对模型进行描述和映射时,分析了HLA对象模型和面向对象模型的区别和联系,建立了用MDA思想描述联邦成员的平台无关和平台相关模型的开发过程框架。

Currently, as the middleware in the distributed simulation, HLA has interoperability problems related to other similar middleware environments. To solve these reusability and interoperability problems, this paper introduces the MDA approach to the design of simulation, attempts to improve the reusability and interoperability of HLA in the whole software lifecycle by using modeling idea of MDA. Using the approach, a federate can be separated into Behavior Logic and Integration Code, and using different models to describe and map them. This approach reduces the complexity and the difficulty of integration. When we describe and map models by analyzing the differences and relations between object models of HLA and OOAD, we establish the PIM and PSM of the federate using modeling idea of MDA.
