摘要
如今Web服务在网络中被广泛应用,但随着需求变更、系统升级等变化的出现,Web服务如何进行相应的发展演化就成为了一个很重要的问题。为此,文中提出量子免疫进化算法的Web服务演化框架,该策略采用量子编码和量子进化操作优化服务选择,从而为服务演化的自动管理、控制提供了良好的知识基础,提高了整体Web服务的质量。为验证方法的有效性,进行了仿真实验分析,与在组合服务中常用的HTN规划方法进行了比较,实验结果表明文中所提方法在整体服务的可用性上更为优秀。
Today,Web services are widely used in the network,but as many variations appearanced,such as demand changes,system upgrades,how to make Web service correspondingly develop has become a very important issue.Thus,propose a model of Web service evolution framework which is based on quantum immune evolution algorithm（QIEA）,and also introduce the methods of quantum coding and quantum evolution operations to optimize the service choices.Generally speaking,it provides a favorable knowledge foundation for the automatic management and control of service evolution which enhances the quality of Web service.In order to inspect and verify the effectiveness of the method,have executed the simulation experiment and compared with the HTN planning method often used in service composition.The experiment results show that the method proposed plays better in the usability.
