Composite pattern of enhancement of quality performance and kansei engineering in emotional design with group decision making models approach

There are many ways to improve the quality of designing and manufacturing products that are more in line with the needs of customers. Studies have shown that, in spite of customer needs, customer sense also plays a major role in designing products. One of the effective ways to identify and use in product design is kansei engineering. In this research, we have tried to use quality function deployment (QFD) and kansei engineering to determine the emotions affecting the design of the product and by combining these two, products can be tailored to meet the needs of customers. The statistical population for the determination of technical properties was the stores that were classified according to the sampling method in each case; a simple sampling method was chosen among buyers. Then, during the interview, 10 prominent vendors with a history of selling health products were used. The technical properties of the product are determined in the form of 21 items and a questionnaire distributed among 50 people in which users were asked to determine what characteristics of the product are more important to them. In this research, firstly, with the help of the previous study, the kansei words were collected in relation to the product, and 13 of them were chosen. These factors were classified into three categories of sensory and appearance features, inherent features and controllable factors. According to the results of a new design for a dishwashing liquid container Presented.
