Abstract

The invention relates to a design decision guidance method based on product feature correlation. The method comprises the steps of collecting and processing market data; establishing a product featureassociation degree matrix; establishing a product feature and part relationship model; establishing a product part correlation degree matrix; performing clustering analysis according to customer requirements or designer requirements; and providing guidance for product design decisions according to clustering results. According to the method, the correlation degree of the product characteristics and the parts is calculated according to the market data by applying a mathematical statistics method, different combinations of the product parts are obtained under the condition of avoiding the influence of subjective factors of designers, and guidance is provided for product design decisions.

Description

technical field [0001] The invention relates to a product design decision-making guidance method based on product big data, in particular to a design decision-making guidance method based on product feature correlation. Background technique [0002] The engineering practice of the past few decades has proved that the global competitiveness of manufacturers is closely related to the rapid response of customers to product specification requirements. Changes to product specifications and their combinations are made through adaptations of physical components. Various types of products, including customized products, reconfigurable products, scalable products, adaptable products and open architecture products, are adaptable to meet changing needs. In order to better facilitate the development of different types of products to meet the changing needs of product specifications, it is necessary to analyze the dependencies between product specifications by considering the relationsh...
