摘 要: | 随着计算机软件发展到开放的软件世界,服务质量(quality of service, QoS),尤其是基于用户偏爱的服务质量,在Web服务选择和组合中变得越来越重要。着眼于面向服务质量(QoS-oriented) 的服务组合问题,讨论当有多个用户同时提出不同偏爱需求时,如何选择一个或一组Web服务使其尽可能满足所有用户的偏爱需求。提出一种基于aCP-net(analogic conditional preferences network)的投票语义机制来解决这个问题。实验结果表明:使用该方法总是可以选择一个较优解,其能够最大限度地满足所有用户偏爱需求。最后给出一个例子来说明该方法的性能。 |
关 键 词: | 计算机应用;Web服务; 服务质量; 服务组合;CP-net;多智能体 |

Abstract: | With computer software being developed in the open world, quality of service (QoS) has become more and more important in Web service selection and composition, especially based on user’s preference. This paper focuses on QoS-oriented service composition and discusses how to select one or a set of Web services which satisfy as many users’ preferences as possible. The solution proposed in this paper is a voting semantic mechanism based on aCP-net (analogic conditional preferences network) on the concept of mCP-nets. Experiment results indicate that using this method can always select an optimal outcome which closely satisfies all users’ preferences. Practical applications are also demonstrated in this paper to show the performance of the approach. |
