Abstract
The traditional approach to materials selection is to compare the results of direct substitution of alternative materials on an individual part-by-part basis. The engineer then frequently faces so many design constraints that use of a new material is infeasible. This approach also precludes redesign to optimize the characteristics of new materials. A methodology is presented which facilitates the consideration of a large system comprised of many components. The management science technique of “multi-attribute utility analysis” is applied as a tool for use by automotive design engineers. Attributes include capital cost, piece cost, weight, design flexibility and corrosion resistance. The results serve as a decision making tool to determine which design provides the greatest overall value. Also, the results may be used as a design aid to quantify desirable tradeoffs between attributes, thus pointing the way towards optimal redesign.
