Assessment of the SEMCO Model-Based Repository Approach for Software System Engineering

Abstract

We have developed a methodological tool support for software development based on the reuse of dedicated subsystems, that have been pre-engineered to adapt to a specific domain. This paper proposes an empirical evaluation of the proposed approach through its practical application to a use case in the railway domain with strong security and dependability requirements, followed by a description of a survey performed among domain experts to better understand their perceptions regarding our approach. The case study enables us to determine that our approach centered around a model-based repository of patterns leads to a reduction in the number of steps in the engineering process or to their simplification. The survey assists in assessing whether domain experts agree on the benefits of adopting the model-based repository approach in a real industrial context.
