Modeling e-service orchestration through petri nets

Abstract

B2B interaction requires new forms of coordination between participating organizations. Indeed, the main requirement is that the autonomy of each participating partner is preserved during the interaction, guaranteeing at the same time that the overall goals of the common process are reached. Mechanisms for regulating distributed workflow evolution when the workflow is composed of the invocation of E-services of different organizations are needed. The E-service orchestration model proposed in this paper provides a mechanism for supporting control of process evolution in terms both of control and data flows, and for distributing and assigning process responsibilities.
