A system-theoretic approach to case management

The Object Management Group (OMG) defined Case Management Model and Notation (CMMN), a modeling specification for case management in early 2013. However, supporting software tools do not exist for this novel concept; and simulation is not taken into account. In this paper, we present a DEVS-based case management system, with which case workers are able to interact with their knowledge work in terms of (1) model representation, (2) model manipulation, (3) model verification and validation, and (4) model implementation. Feature (1) is enabled by CMMN; (2), (3) and (4) are achieved by using a high level simulation modeling language for discrete event system, i.e., DDML (DEVS-Driven Modeling Language).
