基于MDA的两层HLA技术研究

HLA缺乏由仿真模型构建联邦成员的统一开发框架,所有联邦成员均是平等的,即体系结构是一种平面关系,联邦成员级的模型重用仍然是一种静态重用,无法实现模型动态加入不同FOM的联邦。提出了一种基于MDA的两层HLA框架FIA/FEI,首先将MDA引入HLA仿真建模,给出了MDA和HLA融合的途径。继而提出了突破了现有HLA的平面结构的资源管理联邦的思想,以支持对元模型的管理和基于元模型的仿真应用联邦的动态组合和FOM信息的动态配置,实现基于元模型的资源重用与共享,提高了HLA的模型资源动态重用与共享能力,应用实例验证了该框架的可行性。

Abstract：

HLA has not HLA uniformed modeling frame for constructing federates from general simulation models, and its all of federates are au pair, i.e. it is planar architecture essentially, so related models are difficult to enter the federations with different FOM dynamically. As a result, model reusing in federate level is static reusing. MDA based HLA with two levels frame （FIA/FEI） was proposed. At first, the schema of MDA integrated HLA was discussed, then the resource management federate was specified, which broke through the plane architecture of existing HLA and supports the management of meta-models, dynamic configuration of FOM information, and dynamic creation of simulation application federate based on meta-models. This two level frame realizes meta-model based resource reusing and sharing, improving the reusing ability and sharing ability of the model resources for HLA. The application practice verifies the feasibility of double level frame.
