Application of SysMLv1 vs SysMLv2 in the Scope of the MagicGrid Framework

Abstract

This paper aims to assess the impact of the next generation Systems Modeling Language, SysMLv2, on MagicGrid, an established framework for the model-based systems engineering (MBSE). The research involves the parallel application of SysMLv1 and SysMLv2 to build two models of the problem domain definition by following the steps defined by the framework. The paper compares the modeling concepts of both languages used to create the model, discloses differences, and assesses advantages and disadvantages over each other. While SysMLv2 offers both textual and graphical notations, this study primarily focuses on the graphical representation. The paper concludes with a comprehensive summary of distinctions observed in the application of SysMLv2 versus SysMLv1. As anticipated, SysMLv2 was found a completely fresh modeling language. Significant alterations has been observed in the use case specification and functional analysis. Additionally, the absence of explicit guidelines on the utilization of definitions and usages was identified.
