Bao Li, Weishi Zhang, Xiuguo Zhang · 2006
Formal method is an effective way for modeling and verifying concurrent system. An important research field is to describe and verify Web services by formal method. Guaranteeing the validity of Web services composition is necessary for enhancing the value of this composite service. CCS is a kind of process algebra which can be used to model concurrent systems. Web services and their composition are described and modeled based on CCS in this paper. Rules about applying CCS to Web services are explained. Finally, a case study is carried and the validity of composition model is verified. Some important points in verification are discussed
