In view of the difficulty in decision-making for multi-Kansei image design scheme in concept design, a cobweb grey target decision-making method was proposed for multi-Kansei image in product form. Firstly, the cognitive data of the design subjects was obtained by Kansei engineering, and the comprehensive evaluation model based on the cognitive data of the design subjects was constructed using the entropy weight method and game theory. Meanwhile, the weight relationship of each Kansei image was determined based on the comprehensive evaluation data of the design subjects of each image. Secondly, multiple evolution schemes were artificially selected from the product form evolution system, and the spider chart was used to represent the Kansei image relationship of each evolution scheme. A cobweb grey target decision-making model of multi-Kansei image was constructed to calculate the decision-making coefficient, and the relative optimal scheme that conformed to the cognition of the design subjects was obtained by comparing and sorting them. Finally, the feasibility of the decision-making model was verified by applying the grey correlation analysis method. The model can help designers quickly and accurately determine the multi-Kansei image scheme in the design decision-making stage, which provides a new theory and method for the multi-Kansei image decision-making of product scheme.
