An axiomatic design methodology for manufacturing process selection based on multi-user requirements mapping

Abstract

The fundamental principles of Axiomatic Design involve the systematic analysis, evaluation and transformation of customer needs into product functions with the scope of deriving a set of design parameters and process variables. This paper presents a novel methodology based on the application of axiomatic design theory, with the aim of supporting manufacturing process selection by considering the technological capabilities during manufacturing and the functional requirements of the artefact in hand. The proposed model integrates both functional and non-functional requirements by mapping various stakeholder needs. A case study for a release-buckle mechanism used in a rehabilitation device is presented. Results of an initial qualitative evaluation with medical device designers provide a degree of evidence that the proposed methodology is useful during process selection activities.
