Abstract

Abstract: After introducing the 3-layer Web services organization model and the finite state machine of Web services，this paper proposes a new method for automatic Web services composition，obtains a theorem about the combinability of Web services，and proves the validity of the theorem.This method predigests the automatic Web services composition based on finite state machine in BPEL and reduces the process of Web services composition thanks to using the 3-layer Web services organization model.And further more，this paper also discusses the advantage and disadvantage of this method.

Key words: Web services composition, finite state machine, 3-layer Web services organization model, BPEL

摘要： 在研究Web服务三层组织模型和有限状态自动机的基础上，提出了一种新的Web服务组合策略，给出了一个服务的可组合性定理，并证明了定理的正确性。该策略以Web服务三层组织模型为基础，简化了BPEL中基于有限状态自动机的Web服务自动组合，精简了服务组合流程。最后对这种新的组合策略的优缺点作了分析。
