Model Decomposition of Robustness Diagram with Loop and Time Controls to Sequence Diagrams Using Activity Groups

Abstract

The Robustness Diagram with Loop and Time Controls is a workflow model for representing systems that can capture all three aspects of a workflow-resource, process, and case. It can be mapped to Class Diagrams -to extract the resource dimension of the system it represents, to Petri Nets -to extract both process and case dimensions thereof, and Sequence Diagrams -to extract both resource and case dimensions thereof. This paper proposes a mapping of RDLT into Sequence Diagrams that uses the concept of the input model's minimal activity and its activity group to ensure generating outputs that can capture a case management profile. The RDLT components and their mapped Sequence Diagram components are used in the proposed mapping. Such mapping can produce a set of Sequence Diagrams based on the number of objects, for checking arcs and referencing vertices. Furthermore, the mapping was used to demonstrate the partial mapping of the RDLT representation of the Chiller System to a set of Sequence Diagrams. Lastly, we validate the correctness of the decomposition by comparing the consistency of the activity profiles of the RDLT with the case management profiles of their corresponding set of Sequence Diagrams.
