A methodology of concurrent design of machine products based on simultaneous processing of design and manufacturing information is proposed for obtaining better product designs from a global viewpoint, according to the concept of concurrent engineering. In this method, an integrated higher-rank decision-making utility function is formulated using the satisfactory level functions of product design and manufacturing divisions by utility analysis. Then, on the Pareto optimum solution curves of multiobjective optimization problems of the maximization of the product performance and the minimization of the product manufacturing cost, the values of the integrated satisfactory levels are obtained for alternative product designs and the most preferable design solution is selected. An applied example of the concurrent design procedures is given for demonstrating the effectiveness of the proposed method in comparison to conventional design method procedures.
