Delta Rhapsody

Abstract

Model Based System Engineering (MBSE) has become the pre-eminent paradigm used to improve the development of complex systems. Additionally, Delta Modelling provides an incremental approach to the design and maintenance of models when there is variability in the system. In this context, the market leading IBM Rhapsody® provides a professional and wide range of functionalities. Nevertheless, there is not support for Delta Modelling in IBM Rhapsody®. To meet this need, the Delta Rhapsody solution has been developed. With the tool a new variant model can be automatically generated applying deltas to a core model. The application of the solution in an industrial case study has been undertaken. From this, it was concluded that the Delta Rhapsody solution notably reduces the required time to develop a variant model. To further improve the Delta Rhapsody solution, some future works have also been identified.
