A Global Efficiency Optimization Model of Service Evaluation and Selection

Considering the existing service composition model are almost focused on single service composition efficiency, did not consider about the global efficiency and lack of capability of evaluation of inhibition of malicious evaluation, this paper propose a global efficiency optimization of service composition model based on equivalent hierarchical and design a selection of appropriate policy to solve that problem. Experiments and theoretical analysis results show that this model can inhibit malicious evaluation and improved the efficiency of the system.
