Model Checking Business Processes for Web Service Compositions in mCRL2

BPEL has emerged as the de facto industry standard for composing web services. In this paper, we focus on a core subset of BPEL, called BPEL*, and provide a set of rules for translating BPEL* into the process algebra language mCRL2, which can be used to verify properties of BPEL processes. An employee travel arrangement example is provided to show our approach.
