System Engineering Method Based on Axiomatic Design and MBSE Modeling Framework

A fundamental challenge for engineers when applying the MBSE (Model-based Systems Engineering) is to analyze complex design problems in an effective way and to represent a complex system with complete models. Aiming at providing an efficient design problem analyzing process and general modeling framework, this paper proposed an Axiomatic Design Theory (ADT) based System Engineering approach by mapping design domains, design axioms and a “Z” mapping process of ADT to complex system’s design processes, modeling and control processes and information loops respectively. Then a MBSE modeling framework that includes the Requirement Model, Functional Architecture and Physical Implementation Architecture was constructed. The presented method and modeling framework is able to guide system engineers to capture design problems effectively. After that, a case study was illustrated to demonstrate how the presented approach was applied. Last, the paper gave conclusions and future works that show lights on improving the MBSE modeling framework to function in a consistent way.
