基于用户偏好的HTN规划在网格服务组合中的研究

分析了用户对组合网格服务的偏好,对这些偏好的表达进行了研究,提出了一种提供用户偏好选择的网格服务组合方法.该方法利用模糊约束来表达用户的偏好,并将用户偏好满意程度转化为模糊约束满足问题,进而使用分支定界法对层次化任务网络(HTN)进行分解.实验结果表明,用户的满意度有显著的提高.

The research of HTN planning in grid services composition based on user preferences

This paper studied how to compose grid services based on the needs of the customers and how to support the users' preferences and ensure their satisfaction.In the study,the users' preferences and satisfaction are modeled as a fuzzy constraint satisfaction problem(FCSP).Based on this modeling,the hierarchical task network(HTN)is used to compose grid services with the Branch and Bound Method.The experiment results show that this approach improves the users' satisfaction with a trivial performance.
