Change request management in model-driven engineering of industrial automation software

Change request management and Model Driven Engineering (MDE) are two key concepts for industrial automation software in today´s competitive and fast changing environment. However, although there exist frameworks on general change management, they do not exploit the capabilities of MDE. This paper proposes a workflow to combine these two technologies, enabling the engineer responsible for the change to quickly and efficiently create analysis on the impact of the change, as well as the feasibility of a proposed solution. This result of the analysis is presented with concrete SysML model diagrams to better support decision making for a change request. One advantage of performing change management in SysML is the possibility to automate parts of the change analysis process; one step is automated as a proof-of-concept.
