平行仿真技术是近年来系统建模与仿真领域的新兴仿真技术,已经成为研究前沿。从战场指挥决策领域、装备任务规划领域和装备维修保障领域对仿真技术的新需求出发,归纳了以往仿真技术面临的突出问题,即领域模型固定,不具备自适应演化能力。提出了装备平行仿真技术的概念,并指出其应具备的特点,系统梳理了装备平行仿真技术的理论缘起和相关技术研究现状,并对主要相关技术进行了对比分析。在装备维修保障领域中,侧重讨论了面向装备剩余寿命预测的平行仿真技术,分析了模型定位问题和技术框架,探讨了主要建模技术,包括装备退化状态在线感知、装备退化状态空间模型构建、装备退化状态空间模型演化,为下一步开发面向装备剩余寿命预测的平行仿真原型系统提供了技术思路。

Paral lel simulat ion technology is an emerging simulat ion technology in the research area of sys-tem modeling and simulation in recent years which has been the research emphasis. According to the simulation technology demands of battlefield command decision, equipment mission planning and equipment maintenance support, the outstanding problems of prior simulation technologies are inducted, i. e. , the stable domain model without self-evolution ability. The concept of the equipment parallel simulation technology is proposed and its characteristics are pointed out, and the theory origin and related technologies research status are also inducted systematically. The main related technologies are also analyzed comparatively. In the area of equipment mainte-nance support, the equipment remaining useful life oriented parallel simulation technology and the model positio-ning issue and technology framework are analyzed. The main modeling technologies are discussed deeply which include online awareness of equipment degeneration state,establishment of the equipment degeneration state space model and evolution of the equipment degeneration state space model, supporting technology reference for developing the equipment remaining useful life oriented parallel simulation prototype system.
