Research on Hierarchical Modeling of Simulation Model of Cloud Simulation Platform

The simulation model resource is a core resource of cloud simulation platform. For the purpose of efficient development and fast application of simulation model resources on cloud simulation platform, a hierarchical modeling framework was proposed, which include simulation model functional modeling, standardized description, interaction modeling and service-oriented modeling. First, the simulation model was described with standardized XML. Then, using the Basic Object Model(BOM), the simulation interoperability model was built. On base this, the simulation model's service-oriented characteristic was realized. The research achievement was applied in the virtual maintenance simulation system in cloud emulation mode. Through the typical example, the correctness of the proposed hierarchical simulation model resource modeling method was verified. Case studies also show that the application of the simulation model resource hierarchical modeling framework and its key technologies can effectively improve the resource modeling simulation efficiency of cloud simulation platform.
