Decision-based design-driven material selection: A normative-prescriptive approach for simultaneous selection of material and geometric variables in gear design

Abstract

The performance of the material is changed when it takes a human created shape and shape is given on the basis of performance of materials. In this paper we explore the selection of material and geometric variables simultaneously in Hazelrigg's decision-based design (DBD) framework by introducing Suh's design axioms (SDA), Multiple Attribute Utility Theory (MAUT), and Analytical Hierarchy Process (AHP) where the design space is discrete and two stages spur gear reduction unit is considered as a case study. SDA is not a conventional abbreviation. For the sake of diagram and to harmonize with other abbreviations it is shortened as SDA. In SDA customer requirements are translated into functional requirements to generate the alternatives within geometric constraints.
