基于HLA的可扩展模型库构建方法研究

Research of Modeling Method in Extensible Model Library Based on HLA

在HLA仿真框架下,仿真资源的重用是一件意义重大的事情,这也是FEDEP过程要着重解决的问题。然而实际工作中,重用SOM构建FOM的工作经常被不同SOM中类的继承关系造成的语义上的歧义所困扰,究其原因,没有一个统一的模型库视图是其根源。为此,提出一种新的模型库分层构建的方法,这种方法按照对象之间的继承和组合关系把对象模型库分成相互联系的两层,它使得模型库可以自由扩展,避免库中信息之间语义上歧义的出现。

Under the framework of HLA, the reuse of simulation resource is a significant thing which is also the main task in Federation Development and Execution Process. However, in the simulation practices, to reuse SOM for building FOM is always prevented by the confused inherit relationship among the classes in SOMs, and the real reason for this is apparent, not having a uniform model library data view is the cause. A new layered modeling method in model library construction for this was proposed, which divided the library into two related layers according to the inheritance and composition relationship among the objects. The method makes model library extend freely and avoids the semantic conflict in the content of the model library.
