Abstract

Quality-cost modeling is a method for obtaining approximate yet quantitative information regarding the potential of emerging manufacturing processes to produce highquality, cost-competitive advanced materials. The modeling method is based on the concept of an affordability space—a set of reachable combinations of cost and performance (quality) unique to a particular process and material. The analysis relies on the development of relatively simple (first order) models intended to capture the essential interactions between the material and its processing environment and their use in calculating the final microstructure (on which a quality index is based) and the associated cost. Both cost and quality are functions of the starting state of the material, process conditions used, and the design of the process. The tool allows numerical experiments to be conducted in which the influence of these variables on cost and quality can be explored.
