智慧物理系统(cPs)是一个综合计算、通讯和控制的多维复杂系统.首先分析了智慧物理系统的特点以及对现有分布式建模与仿真技术的挑战,进而提出了一种扩展的HLA建模与仿真框架.讨论了四方面新技术,即基于MDA的建模技术,基于协同本体的知识融合技术,资源管理联邦技术,以及互配RTI技术.该框架将目前的HLA的单层结构扩展为双层结构,即资源联邦层与应用联邦层.它实现了基于MDA实现CPS的语义建模,支持多联邦的协同并发运行,以松耦合集成的方式实现大规模、异构CPS的建模与仿真.%A cyber - physical system (CPS) is a multi -dimension complex system integrating computation, communication and control. This paper introduces the features and challenges of CPS at first, and then presents an extended HLA framework for Modeling & Simulation of CPS. The paper discusses four aspects of new techniques, that is, MDA based modeling, knowledge fusion based collaboration ontology, the Resource Management Federate, and Inter - adapted RTI. The framework extends the single layer federate architecture of standard HLA to two - layer federate architecture, I.e. The Resource Federate layer and the Application Federate layer, and supports semantic modeling based on MDA and the concurrent execution of multi - application federates collaboratively, so it enables modeling and simulation of large - scale, heterogeneous CPSs in loosely coupled manner.
