Model-based systems and software engineering (MBSSE) reference model and its relationship to systems engineering process standards

Abstract

Model-Based System Engineering (MBSE) is a formalized application for supporting systems engineering throughout the life cycle of systems of interest (SoI). The MBSE approach is formed into a holistic methodology aimed at the aggressive application of methods and tools for definition, analysis and evolution models throughout the entire life cycle of the system, which ensures increased levels of manufacturability in the implementation of the definition stages and the definition system, increasing the efficiency and quality of life system cycle management process, including the operation and maintenance phase. This is due to: the ability to apply analysis through development method analysis, model automation and validation, analytics support and multiple perspectives at every stage of the system life cycle. And most importantly, this approach provides the ability to reuse the model repository of one project in other projects. In recent years, various engineering fields have successfully used the MBSE approach to develop complex systems; for example, in the field of Internet of Things, mission engineering, cyber-physical systems (CPS), system systems (SoS), digital twins, etc. However, despite many years of successful experience in applying MBSE based on fundamental international-level methodological standards for compliance with MBSE similar Systems engineering standards ISO/IEC/IEEE 15288 and ISO/IEC/IEEE 12207 did not exist until recently. New standard ISO/IEC/IEEE 24641:2023 - Systems and software engineering. Methods and tools for model-based system and software technology is one of the first standards that can claim this role. The article is devoted to a description of the main provisions of this standard, as well as consideration of its relationship with other systems engineering standards.
