[MR08a] Radu Mateescu, Sylvain Rampacek. In Lecture Notes in Business Information Processing, EOMAS 2008, SIGMAS Best Paper Award, Springer, Montpellier, France, Vol. 10, pp. 179-193, June 2008.


Web services are increasingly used for building enterprise information systems according to the Service Oriented Architecture (SOA) paradigm. We propose in this paper a tool-equipped methodology allowing the formal modeling and analysis of Web services described in the BPEL language. The discrete-time transition systems modeling the behavior of Bpel descriptions are obtained by an exhaustive simulation based on a formalization of Bpel semantics using the Algebra of Timed Processes (ATP). These models are then analyzed by model checking value-based temporal logic properties using the CADP toolbox. The approach is illustrated with the design of a Web service for GPS navigation.
