A modular state exploration and compatibility checking of UML dynamic diagrams

Although UML is a suited language for modeling complex systems, the consistency and compatibility checking of designed UML artifacts remains a difficult task because of both the imprecise semantics of UML diagrams and the expressiveness gaps between them. In this setting, this paper uses a modular approach of state exploration to achieve the compatibility checking of the various components depicted by StateCharts and to check that their behavioral models fulfill the scenario-based specifications depicted by interaction diagrams. The main advantages of this approach is to avoid the state explosion problem by achieving the consistency checking in a modular and parallelizable way and by alleviating the handling of component substitutivity without a complete exploration of the whole system.
