Optimal Approach to QoS-Driven Simulation Services Composition
Yabing Zha · Jisuanji fangzhen · 2009
Due to the uncertainty and dynamic character of Web,simulation services that have been chosen under functional matching must promise that non-functional attributes,i.e.quality of services can meet simulation user's requirements.First of all,based on the definition of simulation services composition,composite services' QoS model was built.Further,Q-SSC optimal problem was modeled as a constrained single objective optimal composition problem,which was resolved by an effective heuristic algorithm--SOOCH.SOOCH algorithm has good time performance,and achieves approximate resolutions with 90% similarity to the optimal resolution.
