Evaluation of Conceptual Product Design Solutions using House of Quality-TOPSIS Integrated Methodology

The product design concept selection is an integral part of product development process. It is a team based decision making effort to evaluate the product design concepts generated. In the present competitive market environment, the design team has to identify the design solution which should reflect the customer needs to ensure customer satisfaction. In this paper an attempt has been made to develop a methodology by integrating House of quality (HOQ) and the technique for order preference by similarity to ideal solution (TOPSIS) with a view to identifying the best design solution to meet the customer needs. The Analytic hierarchy process (AHP) is employed to prioritize the customer needs while constructing the HOQ. The proposed integrated methodology has been demonstrated through a numerical illustration in this paper.
