Using UML Activity Diagrams and Event B for the Specification and the Verification of Workflow Applications

Abstract

This paper presents a specification and formal verification technique for workflow applications using UML Activity Diagrams (AD) and Event B. The workflow application is initially modeled graphically hierarchically with UML AD, then the resulting model is translated into Event B in order to check the correctness of workflow models (such as no deadlock, no livelock, fairness,.) automatically, using the B support tools. In this paper, we discuss the contributions and by an example of workflow application, we illustrate the proposed technique.
