摘　　要：近年来国内外学术界和行业界围绕着Web服务组合开展了大量的研究工作,这些研究都把重点放在Web服务组合功能的实施上,而对组合服务质量的研究甚少。在建立Web服务组合优化模型的基础上,将遗传算法引入到Web服务组合中去,提出了基于遗传算法的Web服务组合的优化方法,给出了构建基于遗传算法的Web服务组合模型和求解方法,从而可以提高组合服务的质量,并能够使Web服务组合满足个性化需求。Most of the research works made by academia and industrial community on Web service composition these years are focusing on execution of composition functions the Web services provided, but much less on the quality of Web composite services. In this article it propo- ses the genetic algorithm based methods of Web services composition optimization and its model building as well as the solution approach by importing the genetic algorithm to Web composition services on the basis of modelling the Web services composition optimization, which can be used to improve the quality of service, and to make Web service composition meet the requirement of personalization.
