Dynamic collaborative simulation platform based on semantic interoperations

为了使协同仿真平台支持语义级别的互操作,支持联邦结构的动态调整,增强仿真运行时平台对人员参与的开放性,减少仿真迭代次数,该文提出了一种基于语义互操作的动态协同仿真平台,重点研究了其中的索引-应用联邦架构技术,支持语义互操作的运行支撑系统(runtimeinfrastructure,RTI)和仿真中间件技术,及通用自适应的仿真监控技术等关键技术。应用该协同仿真平台建立了高速列车动车组检测列车的协同仿真联邦,2个仿真案例表明本平台提高了协同仿真过程的灵活性与适应性,验证了其有效性。

A dynamic collaborative simulation platform based on semantic interoperations was developed to support semantic interoperation among federates,to improve dynamic adjustments of federation structures,promote openness to engineers＇ participation,and reduce the number of iterations in simulations.The key methods are a federatied index—application framework,a semantic interoperation supporting runtime infrastructure（RTI） and simulation middleware with a focus on the genetic self-adapting simulation monitor and control system.The platform is applied to collaborative simulations of the detection of high speed trains.Two demonstrations show its effectiveness and flexibility for dynamic collaborative simulations.
