Layered simulation service description framework oriented to cloud simulation

According to the characteristics of multi-granularity resources sharing and simulation services establishment as well as its new demand on Simulation Service Description Framework(SSDF) in cloud simulation, a layered SSDF oriented to cloud simulation was proposed. The semantics of each layer in the framework were defined and formalized in OWL-S, and the researches were applied to the description of simulation services in certain cloud simulation system prototype. The proposed layered SSDF was verified by typical example. The result showed that the layered SSDF oriented cloud simulation was suitable for various multi-granularity simulation resources of cloud simulation system, and could described cloud simulation services in both attribute-semantic and model-semantic. Thus the intelligent discovery and automatic combination of simulation services were supported, and the construction of cloud simulation mode was realized.
