Research and Realization of Collaborative M&S Services in Simulation Grid

Grid is an integrated environment of resources and computing which is currently the research focus in the information area. Simulation grid, which integrates grid technology and M&S technology, will greatly promote the development of collaborative M&S supporting environment. An elementary simulation grid prototype system was built now and this paper emphasizes the research and realization of the complex system (such as aircraft system) oriented collaborative M&S grid services and their portals. Seven kinds of typical collaborative modeling services and their portals were realized and applied to facilitate the collaborative design process. And different application modes and the corresponding collaborative simulation services were developed and adopted to support the simulation running in the grid environment according to the different real-time requirement of the simulation systems
