A Verification Method for Collaborative Business Processes

The verification of collaborative processes is a key issue to consider in cross-organizational modeling methodologies. Some of the existing verification approaches provide only partial support, whereas others impose some restrictions to verify models with advanced control flow, compromise (completely or partially) the enterprise autonomy, or are focused on technology-dependent specifications. In order to deal with these issues we introduce Global Interaction Nets, which are based on Hierarchical and Colored Petri Nets, and the Global Interaction Soundness property, which was adapted from the classical definition of soundness, as the main correctness criterion. The method can be used to formalize and verify models defined with different modeling languages. In addition, we apply the method through a case study modeled with UP-ColBPIP, which is a modeling language for collaborative processes, and formalize its constructs by means of Global Interaction Nets.
