基于FIPA-ACL的高层体系结构互操作性扩展

摘要

Aiming at the disadvantage of lacking flexible interoperation resulting from the fixed federation object model ( FOM) mechanism in the high level architecture ( HLA) distributed simulation, this paper proposes a method of interoperation extension for HLA distributed simulation based on FIPA-ACL, the agent communication language (ACL) put forward by the Foundation for Intelligent Physical Agents (FIPA). Taking advantage of communication technology in multi-agent systems, this method supports the FIPA-ACL based middleware technology to extend the current fixed FOM mechanism. It was showed to be efficient in communication in distributed simulation, improving the flexibility and dynamics of interoperation, and promoting intelligence in distributed simulation. It has the good succession to its former technology and the lower cost to implement. This method was put into practice in a typical distributed simulation example of a complex product, the high speed train, and the results demonstrated its feasibility and effectiveness.%针对高层体系结构( HLA)仿真中联邦对象模型(FOM)固定机制导致仿真系统交互信息灵活性不足的问题,提出了基于国际组织FIPA的智能体通信语言(FIPA-ACL)的HLA仿真互操作性扩展方法.该方法利用多智能体通信技术支持基于FIPA-ACL的中间件技术,以实现对FOM固定机制的扩展.它能提高系统的通信性能,有效改进分布式仿真互操作的灵活性与动态性,提高分布式仿真的智能化水平.该方法是对现有标准HLA的扩展,具有很好的技术继承性,实现成本低.此方法在典型复杂产品——高速列车的仿真实例中得到了实际应用,从而检验了其可行性和有效性.
