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.
