摘　　要：现有的协同仿真方法与支撑平台在仿真模型分布性、建模与仿真的松耦合性,以及仿真运行快速构建等方面还存在许多不足。为此,提出了广域网环境下的协同建模仿真平台框架。通过服务封装组件和联邦运行组件来实现协同仿真系统的模块化设计与快速组建。分析了两种组件的运行管理和优化机制,以组件概念模型空间与支持结构对象空间的映射方法,实现组件的生成和重用。开发了广域网环境下基于组件的多学科协同建模仿真平台,运行了协同仿真工程实例。实验结果表明,组件方法支持快速的仿真系统组建和模型重用,广域网下的协同仿真平台具有良好的仿真分析效果。Current collaborative simulation approaches and supporting platform have pitfalls in integrating simulation models in highly distributed environment,effectively decoupling high-level modeling and simulation, and supporting the rapid construction of a simulation system. To deal with these problems, a component-based framework was proposed to implement collaborative simulation in a wide area network environment. Service encapsulation component and federation execution component were used to realize modularized design and rapid construction of a collaborative simulation system. Operation management and optimization mechanisms for the two components were analyzed. a mapping method was proposed to facilitate the generation and reuse of software components. A component-based collaborative modeling and simulation platform was developed, and a case study was also provided. Experiment results demonstrated that the component-based platform was effective in rapid construction as welt as model reuse, and the collaborative simulation platform in distributed environment had excellent simulation effect.
