Application of aggregate analysis for product design quality using QFD model and TOPSIS

Abstract

The high level of quality is becoming increasingly more important in manufacturing industry due to customer requirements. The selection of proper design quality is vital for the success of new product development. How to select the suitable analysis model to improve the decision accuracy has become a complex problem. This study presents a systematic decision support approach to solve the optimization design problems of product quality based on quality function deployment (QFD) and technique for order preference by similarity to ideal solution (TOPSIS). The experimental results showed that the proposed aggregate analysis model is expected to provide invaluable decision support for the design quality of a gas turbine.
