The application of QFD method in the process of the organization’s QMS for the production of complex household appliances (CHA) is discusses. It is noted that the QFD is virtually supposed to be the only method to date quality management tool that allows you to quickly consider the opinions of consumers in the design process of modern complex household appliances. However, this method is not widely used because of the complexity of the transfer of opinions and expectations of consumers in the technical characteristics of the product, since it is based on a subjective interpretation of technical experts qualitatively consumer demands. It is proposed the use of certain methods of the theory of fuzzy sets to eliminate this disadvantage of the QFD method and provide translation of fuzzy opinion of the consumer to product technical parameters by the calculated method. In addition, it is shown that the use of reQFDanalysis after studying by the focus groups the results of sample tests on the major consumption function significantly reduces the asymmetry of market demand for complex household appliances.
