Abstract
As interactions and communication between elements in engineered systems continue to
increase, the need to manage complexity, mitigate risks and improve human understanding of a
system behavior becomes important. Over the years, systems engineering has emerged as a
way to address the design of complex systems. However, traditional systems engineering comes
with its own limitations, and this has led to the emergence of Model-Based Systems Engineering
(MBSE) which aims to provide a better solution of design of complex systems. A lot of MBSE
approaches are still based on heuristics and sometimes there is no clear structure on the process
of design, especially during product and process decomposition. This paper aims to address
that gap through the introduction of a formal structure by integrating concepts from Axiomatic
Design Theory with the Requirement, Functional, Logical and Physical (RFLP) framework
used in MBSE. The axioms from axiomatic design guide the decision-making process and the
zigzagging aspect of the theory aids in the development of a structure during design. This
process also aids in the identification and mitigation of potential coupling in design. A coupled
spring-mass-damper system will serve as a demonstration to verify the proposed approach
