Software and Methodological Toolkit for the Design and Development of Technical Devices in the Model-Based Systems Engineering Paradigm

Model-based systems engineering (MBSE) and its' tool the Systems Modelling Language (SysML) are recognized to serve as the fundament for design and development (D&D) of system models and digital twins. But the existing MBSE software (SW) tools based on SysML are complex and expensive. The paper raises the question: “Is it possible to make usage of MBSE software and methodological tools during space instruments design and development (SIDD) available to a wide audience of potential users?” To answer this question, for SIDD lifecycle phases (LPs) were developed methodological tools (MTs) based on improvements of such MBSE tools as Quality Function Deployment (QFD), House of Quality (HoQ); SysML, and their synthesis with systems engineering (SE) tools. MTs were implemented in the widely available SW tools. Proposed MTs allow to reduce time required for SysML requirements diagram development and update from several days to minutes; for LPs realization from 5 to 10%.
