A Model Driven Engineering Approach for Modelling Versions of Business Processes using BPMN

This paper presents a solution to model and specify flexible business processes using the version concept. This solution advocates a driven engineering approach considering at the CIM level, a specific meta-model, the Version Business Process (VBP) meta-model for modelling versions of Business Processes (BP), and at the PIM level, an extension of the BPMN meta-model for visualizing and user validating the modelled BP versions. This paper introduces the VBP meta-model, presents the extension of BPMN we propose to specify versions of BPs, and illustrates how we automatically map, using QVT rules, BP versions modelled using the VBP meta-model onto corresponding extended BPMN ones. This solution is intended to business process designers: it supports them for modelling and specifying flexible business processes using the version concept.
