The work aims to establish a comprehensive aesthetic evaluation model of product form integrating the subjective and objective evaluation methods by the combination weighting method of game theory, so as to overcome the limitations of the single subjective and objective evaluation method in aesthetic evaluation. Firstly, based on the existing aesthetic index system and formula of product form, the aesthetic index values were calculated. Then, the semantic difference method was used to conduct a questionnaire survey to obtain the aesthetic evaluation value. Next, the subjective and objective weights of each aesthetic index were calculated by the grey relational analysis method and entropy weight method. Finally, the combination weighting method of game theory was applied to solve the comprehensive weights of the aesthetic indexes and construct a comprehensive aesthetic evaluation model of product form. With the frontal form of the translator as the object, the two-level progressive ranking method was used for the experimental verification of aesthetic evaluation. According to the results, the method had good reasonableness and reliability. The aesthetic evaluation method of product form based on the combination weighting method of game theory can quantify the beauty of product form layout characteristics well and provide quantitative theoretical guidance for the optimal design of product form layout.
