Weight evaluation of comprehensive evaluation of difficulty in mechanical structure design of toy products based on ANP

Abstract Human society is currently in the era of the knowledge economy, and quantitative measurement of the difficulty of product design provides a basis for enterprises to further implement rational resource allocation, which has important practical significance for enterprises. Based on the actual situation of the enterprise, this study aims to gain a deep understanding of the development process of toy products and establish a comprehensive evaluation index system suitable for evaluating the difficulty coefficient of the mechanical structure design of toy products. The study determined the evaluation indicators that affect the difficulty of mechanical structure design in the product development process through investigation and analysis methods and used the network analysis method to determine the weights of relevant evaluation indicators. Finally, the design difficulty coefficient of toy products was obtained by weighting. ANP comprehensively considered various factors while considering the mutual influence between them, describing and calculating the relationship between each factor, and conducting a comprehensive ranking. Several examples were conveniently calculated by using Super Decisions software, and the results showed that the application of ANP to evaluate the difficulty of mechanical structure design for toy products is reasonable.
