From BPMN2 to Event B: A Specification and Verification Approach of Workflow Applications
2019
The BPMN2 language suffers from the absence of a precise formal semantics of the various notations used, which often leads to ambiguities. In addition, this language does not have a proof system that validates a BPMN2 specification. Consequently, the use of a formal method, such as Event B, is a solution for dealing with the shortcomings found in the BPMN2 language. We propose in this paper a model-driven approach based on meta-model and meta-model transformation implemented in KerMeta to specify and formally verify workflows.
