Optimum selection of a composite product system using MADM approach

The paper describes a methodology for evaluation, coding, ranking, and optimum selection of subsystems for composite product used directly by its manufacturers. This method is important from the point view of development of a reliable database, virtual design, customization, developing cutting-edge technology, and meeting the challenges of global competition in composite industry. The 77-attribute electronic coding scheme and the evaluation techniques presented in this paper are useful to the designer during all the phases of design process, and manufacturer for the selection of optimum subsystems, which meet global market requirements. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is a Multiple-Attribute Decision Making (MADM) approach, used for selection of subsystems for a composite product development in order of preference for given application. Two graphical methods of MADM approach for evaluation and comparison are also introduced. The proposed 3-stage selection methodology is explained with an illustrative example.
