Modelling and verification of interorganizational workflows with security constraints: A Petri nets-based approach

Abstract

Interorganizational worfklows represent workflows which involve several business processes, belonging to different organizations, which need to coordinate thier actions in order to achieve a common goal. This paper proposes a Petri net model which permits the modelling and verification of interorganizational workflows. The model allows the explicit representation of the organizational dimension of each component workflow, the shared use of resources among different organizations as well as the specification of security constraints. A property of soundness, which describes the correct execution of the interorganizational workflow, is defined and proven decidable. © 2012 Springer-Verlag.
