基于服务质量的动态 Web 服务组合方法研究
RESEARCH ON QUALITY OF SERVICE-BASED DYNAMIC WEB SERVICE COMPOSITION METHOD
摘要
Abstract
For the problems in Web service composition such as the fixed weight,inflexible choice and poor performance,etc.,we put forward a quality of service-based variable weight dynamic Web service composition method (VW-DWSC-QoS)by the improved genetic algorithm.The VW-DWSC-QoS method uses the variable weight QoS parameters,introduces the penalty function strategy,and dynamic adjusts the variable weight factor,crossover and mutation factor,these makes it good in finding the Web service compositions meeting users need within a relatively short period.Theoretical analysis and simulation experiments all show the feasibility and effectiveness of this method, and compared with the traditional method,its optimal solution has better quality of service and fitness.关键词
