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.
