摘　　要：针对SOA系统中服务动态组合的可靠性问题,提出了Web服务工作流的最优冗余优化。同时,在重定义粒子群算法的基础上,结合遗传算法中的交叉、变异思想,设计了一种基于改进粒子群优化算法的QoS(quality of service)调度策略,最后通过仿真实验证明了算法的有效性。Based on the fact that Web service dynamically changes in SOA projects, a redundancy optimization of Web Service workflow is established. At the same time, on the basis of redefining the particle swarm algorithm, combining with the cross and mutation operations in genetic algorithm, the QoS scheduling strategy based on improved PSOA is designed. At last, the experimental results of this algorithm are presented.
