Research And Realization Of Simulation Model-Base

"Simulation is an activity based on model". With the development of simulation,the object of simulation becomes complex, the type of simulation model becomes more and model management become fussy increasingly. In order to use simulation model effectively that we need build simulation model base and its management system. The scope of simulation is enlarging and the complexity of its system is increasing incessantly. The simulation model base will become important part of simulation system.To build distributed simulation model base system and realize its management of simulation model need resolve many key technologies such as model storing, model accessing, model classifying, model describing, model sharing and model management and so on. This paper is about to resolve those problems. We will use XML, database and Web technology to build the framework of simulation model base system.This paper researches models of HLA FEDEP from the view of model reusing; it sorts the model of HLA FEDEP for the first time. The paper brings out a method of model description which based on web after researching the meta-data of simulation model, and it points out the methods of model storage and management of model in HLA after analyzing the technologies of model storing, management and version management. After that, this paper designs the framework of simulation model-base system based on web using technique of XML, database and web. It realizes some functions of the system, such as model storing, model searching, model deleting, model downloading, user managing, system maintenance, information releasing and so on. It also realizes the integration of the system and other tool of KD-HLA.The system has been used in projects of cooperation departments.
