Abstract. As Web services become the dominant technology for integrating distributed information systems, enterprises are more interested by these environments. However, enterprises socio-economic environments are more and more subject to changes which impact directly business processes published as Web services. In parallel, if at change time some instances are running, the business process evolution will impact the equivalence and substitution classes of the actual service. In this paper, we present an equivalence and substitution analysis in dynamic evolution context. We suggest an approach to identify residual services that can substitute a modified one, where ongoing instances are pending. Our analysis is based on protocol schema matching and on real execution traces. The proposed approach has been implemented in a software tool which provides some useful functionalities for protocol managers.
