摘要
针对Web服务组合中动态优化选取问题,设计了支持Web服务组合的Web服务评价模型和一个三层结构组织模型。在充分考虑Web服务之间的接口匹配问题的基础上,提出了一个基于赋权多段图最长路径选择策略的Web服务全局优化选取方法,并提出了动态规划、线性规划以及遗传算法进行Web服务动态优化选取。基于赋权多段图的Web服务优化选取方法,有效解决了Web服务组合中Web服务的接口匹配问题,使Web服务的选取更加准确。
Focusing on the dynamic optimization problem in Web service composition, a Web service evaluation module and a three-layer structured module in support of Web service mechanism are designed. The traditional problem of interface matching for Web services is well solved and an optimized algorithm is presented to dynamically select the maximum path based on weighted multistage graph, in which dynamic programming, linear programming and inheriting algorithm are illustrated respectively. The efficiency of interface matching for Web service composition and accuracy in Web service selecting can be significantly and effectively improved.
