摘要
服务选择算法是影响组合服务的QoS和服务组合性能高低的关键因素。针对近几年来基于QoS的Web服务选择算法的发展状况进行了综述,介绍和总结了当前基于QoS的Web服务选择问题模型,对服务选择策略进行了分类,并对当前的一些典型的基于QoS的Web服务选择算法进行了系统的分析和评论。最后指出了现有算法中的不足之处,展望了该领域的进一步研究方向。
The algorithm of services selection is a key factor which can affect the QoS of composite service and the performance of services composition. This paper reviewed Web services selection algorithms based on QoS in this field in the recent years. Firstly,introduced and summarized the problem and model of Web services selection,and assorted the strategies of services selection. Then systematically analyzed and discussed a number of classic and popular algorithms of Web services selection based on QoS. Lastly,pointed out several drawbacks of existing algorithms and proposed some research directions of this field for the future.
