摘要
为了在服务组合过程中高效地发现、选择满足用户要求的Web服务,提出一种基于Pareto多目标遗传算法的QoS全局最优服务选择算法(PGA-WS)用以实现用户对组合服务质量的要求。该方法产生一组满足约束条件的Pareto最优方案集合,用户根据实际需要或目标函数的偏好,从Pareto最优集中挑选最满意的组合方案作为组合服务选择问题的最优决策方案。实验结果说明了算法的可行性和有效性。
In order to find and select the appropriate Web services which meet the requirements of users efficiently in the process of Web services composition,a pareto-based multi-object genetic algorithm for Web services selection with Quality of Services(QoS) global optima(lPGA-WS) is proposed to achieve the users'requirement of the QoS.PGA-WS is utilized to produce a set of optimal Pareto services composition process with constraint principle,and the most approving solution is selected as the final decision project according to users'requirements and predilection.The experimental results indicate the feasibility and efficiency of this algorithm.
