Multilevel Modeling for Business Process Automation

Many real-world situations are more easily represented using multilevel models that abandon traditional two level instantiation. In business process management, multilevel modeling allows for the explicit representation of the interdependencies between the processes at the different hierarchy levels within an organization. Furthermore, multilevel modeling allows modelers to capture the variability of processes. The multilevel business artifact (MBA) is a conceptual-modeling primitive for the artifact-centric representation of business processes at multiple levels of abstraction. The (semi-)automated execution of the thus modeled business processes requires a suitable logical representation format for MBAs as well as an execution engine. In this paper, we propose a logical representation for MBAs based on State Chart XML as well as an execution engine based on XQuery.
