THE SYNTHESIS OF MODEL-BASED SYSTEMS ENGINEERING APPROACHES AND TOOLS INTO A METHODOLOGICAL TOOLKIT FOR THE DEVELOPMENT OF TECHNICAL SYSTEMS: THEORY, ITS VERIFICATION AND VALIDATION

Abstract

It is required to shift from separate life cycle (LC) stages to a single project implemented in the model-based systems engineering (MBSE) paradigm. However, MBSE software (SW) tools based on Systems Modeling Language (SysML) are complex and expensive. The paper raises the question, "Is it possible to make available MBSE SW and methodological tools (SMT) to a wide audience of users?" To address this question the following MBSE tools were considered: SysML, Quality Function Deployment (QFD) and House of Quality (HoQ). Their drawbacks were identified and solutions were proposed. All solutions were synthesized into a single methodological toolkit that allows in the automated way to create and update SysML requirement diagrams. Its implementation improves the quality of current projects by up to 10%, speeds up the planning process of analog projects by 60% and allows to implement projects in the MBSE paradigm wherever costly SysML SW tools are not available.
