Application of automated revision for UML models: A case study

Abstract

Modern systems often need to address changing environment and/or faults. The economic and practical issues dictate that the existing models and/or programs be reused while providing fault-tolerance in the presence of faults. Our paper proposes a framework of automated revision of existing program design modeled in UML to add fault-tolerance. Our framework starts with program design modeled in UML state diagram, and then automatically transforms design model to the corresponding underlying computational model. Subsequently, automated revision algorithms are applied to the underlying computational model. Finally the revised program model is converted into an UML model that provides the desired fault-tolerance property. We illustrate the whole work-flow with a case study from automotive systems. © 2012 Springer-Verlag.
