House of Quality

Customer requirement is an effective factor in selecting and rating suppliers. In this regard, auto-making companies concern suppliers who consider requirements of customers in designing and presenting product. This paper presents an approach for identifying proper criteria to assess suppliers in which cover all of customer wants, via the fuzzy-QFD and House of Quality approach; such that after identifying requirements of customers and criteria related to evaluation of suppliers, they are placed in house of quality. After required steps, we can yield the intensity of correlation between supplier’s evaluation criteria and customer’s wants. Questionnaires were used for implementing this approach. Verbal variables (very low, low, average, high, very high) were used in the questionnaires and then, triangular fuzzy numbers replace these variables for calculation and resolving ambiguity. In modern world, increasing production volume and diversity of products by companies, especially auto-making companies, has encountered these companies with enhancing supply chain and selecting suitable suppliers
