New model-based systems engineering methodology based on transdisciplinary quality system development lifecycle model

Abstract

The development of complex systems with multiple constraints is the research hotspot in recent decades. The models-based systems engineering (MBSE) methodologies are often adopted to develop such systems, but they cannot cover all system development dimensions (SDDs). Therefore, this paper attempts to propose a new methodology for developing the said systems, aiming to minimize development time and cost and maximize system quality, orgaizational efficiency and user satisfaction. The transdisciplinary quality system development lifecycle (TQSDL) model was modified to serve as a generic MBSE methodology. Both Quality Function Deployment (QFD) and the dependency structure matrix (DSM) were integrated into the TQSDL process. The proposed MBSE methodology fully cover all SDDs, the roles of the Systems Engineering Manager (SEM) and the systems engineering (SE) processes. In addition, the methodology enables developers to estimate the changes of development cost induced by changing user demands.
