| Abstract: | Based on the defects in the reliability and efficiency in existing web service com-bination,a strategy of Optimization WEB services based on global QoS and immune Particle Swarm algorithm is presented in this paper. Further,we give a best method of building and selecting Web services,which will overcome the limitations of brute-force computation and genetic algorithms in the traditional method effectively. Our experimental results show that the time of combination of service is short,and the efficient combination of service is high-er,which is good to solve the NP problem such as WEB services portfolio. |
