Research On Key Technologies For Resource Management System Under The Integrated Enviriment Of M&S

Integrated modeling and simulation environment is a collection of simulation software, which can support the model designing, model developing, data preparation and data analysis. It also supports procedure complicing, procedure running and other simulation-related applications. What's most important is that the integrated modeling and simulation environment is based on the simulation resource database.Common management system of simulation resource just plays the role of storing the resource files. It doesn't care about the links between simulation resources, but also doesn't meet the purpose of integrated management of resources. In the project of modeling and simulation, in order to improve the efficiency of simulation and modeling, we often need to describe the simulation resources in a standard format. It promotes the integrated management of resource, and improves the reusability and utilization of simulation resources.The dessertation focuses on the description and management of simulation resource in the modeling and simulation, and studies the key technologies under the integrated environment of modeling and simulation as follows:Firstly, this paper studies the framework of models. It uses the object-oriented method to analysis the elements of modeling and simulation, and establishes the framework of modeling and simulation in order to improve the management of models.Secondly, this paper proposes the method of four elements. The XML-based method gives a formal and globally consistent description of the resource in the integrated modeling and simulation environment. The formal description method improves the reusability and commonality of the simulation resource.Thirdly, this paper discusses the combination of BOM-based model and its dynamic management techniques. By studying the interfaces of BOM components, it uses the state machine to analysis the combination of BOM. It establishes the coding system of models, and realizes the dynamic management and storage of models.Fourthly, this paper studies the key technologies of case-oriented simulation resource database. By designing the process, structure, function and interface of simulation case, the system can effectively manage the resources of the task in an integrated way, and support the whole process of modeling and simulation.This paper studies many key technologies, promotes the development of the simulation resource database, and improves the managment level of simulation resource. In a word, it's significant for building the integrated modeling and simulation environment.
