Including non-functional requirements in the Axiomatic Design process

Axiomatic Design Theory is a general framework for system design process based on mapping between several domains. In the Axiomatic Design theory, only the functional requirements (systems´ functions) are considered in the design process, since the mapping between requirements and design parameters in Axiomatic Design does not include non-functional requirements (systems´ attributes). This paper introduce an extended view of system design process based on Axiomatic Design Theory framework to incorporate the non-functional requirements into the mapping between the problem domain and the solution domain. A systematic way of including the non-functional requirements in the design process is presented and an extended design matrix is introduced, which includes the mapping between a complete set of requirements (functional and non-functional) and a corresponding design parameters (physical domain).
