A knowledge mining method for product performance transmission

Abstract

The invention discloses a product performance conductive knowledge mining method. Product performance relevant parameter data changing conditions before or after the conversion of an extension configuration design element are mined, conductive knowledge of performance and special parameters are obtained, and direct conductive relationships among product performances are produced. The method comprises the following steps: extracting the performance information before or after the conversion, obtaining conductive performance features through threshold value judgment, quantificationally describing performance conductive influence degree by conductivity, obtaining extension classification knowledge caused by conductive conversion through performance correlation functions after the conductive conversion, and guiding product design process of performance drive. According to the product performance conductive knowledge mining method, the conductive knowledge of the performance and the special parameters are obtained, and the direct conductive relationships among the product performances are produced, so that the method can help a designer to make a favorable decision in the product design process of demand drive.

Description

technical field [0001] The invention proposes a product performance conduction knowledge mining method, in order to obtain the conduction knowledge between product properties, and generate the conduction relationship between the product properties. Background technique [0002] Products are constantly updated during the development process, and the number of product instances also increases rapidly. The effective construction of the example library can manage product instance information well and improve product development efficiency. However, in the absence of powerful tools, the massive product-related data stored in various data media has far exceeded the ability of human understanding and generalization. Therefore, in the process of product design, how to extract useful knowledge and information from these data through effective methods has always been a concern of enterprises. [0003] The customer's demand description is relatively vague, and generally it is only a ...
