[0020] The present invention will be further introduced below in conjunction with the drawings.

[0021] (1) Analysis of the degree of correlation between design parameters and performance indicators

[0022] 1) Determine the reference sequence and comparison sequence

[0023] According to the normalized data of m performance indicators and n design parameters, each performance indicator is used as a reference sequence, and n design parameters are used to compare sequences. Let the reference sequence be

[0024] Y t =[y t (1),y t (2),…,y t (p),…,y t (q))(1)

[0025] Where Y t Is the reference sequence of the tth (1≤t≤m) performance index, [y t (1),y t (2),…,y t (p),…,y t (q)) is Y t Reference sequence data in.

[0026] Let the comparison sequence be

[0027] X s =[x s (1),x s (2),…,x s (p),…,x s (q))(2)

[0028] Where X s Is the comparison sequence of the sth (1≤s≤n) design parameter,

[0029] [x s (1),x s (2),…,x s (p),…,x s (q)) is X s Compare sequence data in.

Abstract

The present invention provides a product concept performance evaluation method based on performance prediction, which can evaluate new product concept proposals in a quantitative manner, and utilize existing historical product design information to the greatest extent to support proposal evaluation. It includes the following steps: the first step: determine the performance index as the evaluation standard, and determine the weight of each performance index; the second step: analyze the historical product design information, and determine the key design parameters of each performance index; the third step: use the support vector The regression method analyzes the historical product design information, and uses the key design parameters to establish the prediction model of the corresponding performance indicators; the fourth step: take the key design parameter values ​​​​of the new product concept plan as the input of the SVM prediction model, and calculate the various performance values ​​of the plan. Prediction; the fifth step: according to the performance index prediction value of each conceptual scheme, the ideal scheme and the negative ideal scheme are defined first by using the VIKOR method, and then the optimal conceptual scheme is finally determined with the compromise planning method as the core.

Description

technical field [0001] The invention belongs to the field of product concept design, and relates to a product concept performance evaluation method based on performance prediction. Background technique [0002] In the fierce market competition environment, new product research and development capabilities are an important source for enterprises to maintain competitiveness. In the process of product development, conceptual design is the most important and critical link that can best reflect product innovation. Its main task is to complete the generation and evaluation of product concept proposals. The evaluation of concept proposals is the process of scoring a series of generated concept proposals under different evaluation indicators, and then selecting the optimal concept proposal. Since the conceptual design is in the early stage of product development, the quality of the conceptual scheme will have a great impact on the subsequent stages of product development. Studies...
