中文摘要:
      研究了高层体系结构(HLA)下基于设计模型的仿真建模在虚拟产品开发中的应用,提出了一种基于DS理论的HLA协同仿真建模方法。该方法根据上游设计模型的主模型本体实例,使用领域规则和DS不确定性推理创建实现不同目标的仿真模型,进而基于产品资源联邦动态创建HLA仿真任务的联邦对象模型(FOM)和仿真对象模型(SOM),并实现将协同仿真结果通过HLA支撑环境动态返回上游设计模型。建立了复杂产品协同仿真平台原型系统,通过实例验证了该方法的可行性。该方法保证了基于设计模型的HLA协同仿真建模的语义一致性,提高了建模效
英文摘要:
      This paper pays its attention to CAD model based collaborative simulation modeling for virtual product development under the high level architecture (HLA), and gives a novel HLA collaborative simulation modeling method based on the Dempster Shafer (DS) theory. The proposed method using ontology reasoning and the Dempster Shafer theory for uncertainty reasoning, to create different simulation models for different objectives based on the basic belief assignment and the master model ontology, and then, a product resource federation is constructed, which could dynamically generate the federation object model (FOM) and the simulation object model (SOM) for specific simulation tasks based on the DS theory. The method could also send collaborative simulation results back to CAD models. A prototype for HLA collaborative simulation and an industrial case were well established to demonstrate the feasibility of this method. The method could maintain the semantic consistency in collaborative simulation modeling and improve the modeling efficiency.
