Abstract
During the era of Intelligent Manufacturing 4.0, in order to improve the overall competitiveness of machine tool companies, the work aims to propose a scientific industrial design method to guide design innovation, and construct an evaluation model based on product family theory to evaluate the effectiveness of the design scheme. An integrated design selection methodology incorporating the Structural Equation Model (SEM) and Grey Comprehensive Evaluation (GCE) was adopted in an innovative manner. By leveraging the product DNA theory, a thorough theoretical analysis was carried out to key factors in the design of machine tools. A research logic following the hypothesis-verification-quantitative evaluation framework was proposed and the priority ranking of various indicators was determined through quantitative data. Initially, the Structural Equation Model (SEM) was employed to propose preliminary theoretical hypotheses. Subsequently, the empirical validation of the research model was conducted through the assessment of seven-point scale questionnaires. Finally, the coefficient normalization algorithm and Gray Relation Analysis (GCE) were integrated to rank the importance of key factors. This method can effectively evaluate the key factors of machine tool product design, and accordingly produce an industrial design optimization scheme. Through the fusion design decision method of Structural Equation Model and Grey Comprehensive Evaluation, it can effectively guide enterprises to formulate product design strategies and provide a scientific and feasible path to realize product optimization.
