摘要
为实现DEVS在智能建模与分布仿真能力方面的扩充,研究了基于HLA的Agent-DEVS协同仿真建模方法.以并行DEVS为基础,提出了Agent-DEVS联邦模型的形式化描述;将Agent-DEVS模型端口转换为HLA数据对象,确定了Agent-DEVS联邦模型结构,并分析了通信机制,分别建立了Agent-DEVS的知识更新与HLA的属性更新间的映射,以及Agent-DEVS的模型耦合与HLA的实例交互间的映射;最后结合抢险救灾物资保障的仿真建模进行了应用.结果表明,HLA体系框架增强了Agent-DEVS模型的可重用性;知识更新机制丰富了Agent-DEVS模型的互操作性;同时,Agent-DEVS模型的自治性与独立事务处理能力得到了进一步提高.
In order to extend the DEVS with abilities of intelligent modeling and distributed simulation,a collaborative modeling and simulation method for Agent-DEVS based on HLA was studied.The formal description of Agent-DEVS federate models based on Parallel-DEVS was proposed.The models ports in Agent-DEVS were translated into data objects in HLA and the structure of the models was given.The communication mechanism was analyzed.The mapping between knowledge update in Agent-DEVS and attribute update in HLA,and that between models coupling in Agent-DEVS and instances interaction in HLA,were established respectively.Finally,the modeling and simulation application for material supply in emergent disaster was put forward.The results show that the reusability of Agent-DEVS models is enhanced by HLA and the interoperability of the models is enriched by knowledge update mechanism.In addition,the autonomy and independent ability for transaction processing are improved significantly.
