Summary:

Quality Function Deployment (QFD) technique is a quality improvement tool that

reflects customer needs and requirements to product and production process. The

importance rating of technical characteristics in traditional QFD is determined only by

customer requirements (CR), without taking into account such factors as technical cost,

environmental impact, ease of implementation, worker effect. In this study, unlike the

literature, the importance rating of technical characteristics (TC) were determined based on

the principle not only to meet customer satisfaction levels but also to comply with

company interests and the proposed multidimensional model has been implemented in a

firm operating in the forest industry. Different types of questionnaires were created

according to the customer structure in the House of Quality and the importance ratings of

customer requirements were calculated by Goal Programming (GP). Data Envelopment

Analysis (DEA) is integrated with QFD in terms of whether the TCs are effective for the

firm. The linguistic expressions of experts in the construction of relations in the House of

Quality were transformed into fuzzy numbers. The use of GP, DEA and fuzzy logic in the

proposed model shows that QFD is an interdisciplinary method. Method is also reliable

and realistic because its results come from a numerical basis.
