基于QoS关联的Web服务组合算法

摘要

In order to represent the relation between different Web service classes, service requester's preference as well as internal relation between different Quality of Service(QoS) factors in Web service composition, this paper proposes a determination algorithm of Web service composition based on QoS relation. And in evaluating the quality of service composition, it can consider relations on QoS properties between different service classes to some extend. Result shows algorithm holds good executive efficiency, stability as well as outstanding selecting result.%为反映Web服务组合过程中服务类之间的关联性和客户对服务非功能属性的偏好,以及服务调用过程中不同服务质量(QoS)属性之间的内在关系,提出基于QoS关联的Web服务组合决策算法.在评价服务组合优劣程度的过程中,考虑服务类在QoS属性士的关联关系,对QoS数据进行统一规格化和综合评估.实验征明,该算法拥有较好的执行效率和稳定性,并且选择结果较优.
