MBSE for Performance Analysis and Tracing in Preliminary Design Through SysML Diagrams

Nowadays, the high competitiveness in the global market pushes companies to pursue innovation with the aim of reaching profitable results. Even if the adoption of Model-Based System Engineering (MBSE) as an innovative approach for robust design is rapidly spreading in companies, there is still a lack of collaboration between system engineers involved in the requirements management and architectures modelling, and designers of specific systems. For this reason, the present work aims to better connect the system description process with the solving process through the adoption of specific SysML diagrams during preliminary design steps. A direct connection between requirements and design parameters is proposed by means of a well-defined process that fits into the wider V-Model for system development. The whole process enables (i) the rapid development of new models focusing on the connection between requirements and parameters, (ii) tracking of the designing process as well as (iii) the evaluation of performance requirements. This approach is applied to a case study of the Thermal Management System for a hybrid-electric aircraft, focusing on enabling the connection between system description and system development.
