Multi-Objective Optimization in Engineering Design

Chapter 2 introduces the reader to multi-objective optimization problems, namely the general approach that is used when complex problems with conflicting objectives are to be faced. This will allow the reader to become confident with the principle of how an optimal solution is to be sought in a scarcity environment where maximum utility decisions are not configurable with the best materials as far as their properties are concerned, and with the best compromises needed, which have to be made so as to compete and succeed on the market. Starting from a general overview of Quality Function Deployment, QFD - a tool historically developed at Mitsubishi's Kobe - we go on to illustrate how this has been developed for the precise purpose of screening and assessing engineering materials to maximize common "utility" as regards "choice in scarcity".
