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.

A Model Repository Description Language - MRDL

“…The following is a list of high level requirements which were established by the Semco Project [28] and the TERESA Project [29] and which also target lacks in existing model repository building processes. The following set of requirements does not represent a complete set of requirements for any arbitrary model-based repository, as such a set depends on the application domain.…”

A Design-Task-Oriented Model Assignment Method in Model-Based System Engineering

“…To reuse existing models, appropriate models should be identified and assigned to each of the design tasks in the development project. While literature on model reuse has described approaches for applying development environments [22], ontologies [23], and model repositories [24,25], no previous studies have discussed model assignments. erefore, this study focuses on the establishment of a design-task-oriented model assignment method to support model reuse in MBSE.…”
