Debugging of BPMN Processes Using Coloring Techniques
Résumé
A business process is a collection of related tasks organized in
a specific order whose overall execution solves a specific service or product.
BPMN has become the standard workflow-based notation for developing
business processes. Designing business processes using BPMN is however
error-prone. Recent works have proposed verification techniques for analyzing
processes and for detecting possible issues. In particular, model checking is an
established technique for automatically verifying that a model (e.g., a BPMN
process) satisfies a given temporal property. When the model violates the
property, the model checker returns a counterexample, which is a sequence of
actions leading to a state where the property is not satisfied. Understanding
this counterexample for debugging the process is not an easy task, especially
if the counterexample is not expressed using the original notation (BPMN
here). In this paper, we focus on the model checking of BPMN processes.
When properties are violated, we propose to transform counterexamples back
on to the original BPMN process in order to simplify the debugging steps. To
do so, we rely on coloration techniques. The approach proposed in this paper
is fully automated using several tools and was validated on many examples.
