DETERMINING DESIGN ATTRIBUTES OF A SMALL HOUSEHOLD APPLIANCE USING FUZZY VIKOR-BASED QFD METHOD

Abstract

Abstract

Due to globalization, competition for firms is growing with the growth of markets. Quality Function Deployment (QFD) is a systematic approach which is developed in order to pre-plan the product specifications, process specifications and production stages in the design phase in order to reflect the customer's requests and expectations to the product. This study is concerned with the design of a pomegranate extractor that can be easily used in homes and workplaces according to the desired customer demands. The fuzzy VIKOR method was used to increase the reliability of subjective judgments in the QFD, for determining the relative importance weights of customer needs “WHATs” and ranking design attributes “HOWs”. The solution obtained by fuzzy logic is compared with the solutions obtained by the classical QFD and the small home appliance is designed visually by presenting the evaluations.
