Study on Quality Evaluation of Automobile Surfaces Based on Fuzzy Comprehensive Evaluation

Abstract

Abstract:

To evaluate the quality of automobile surfaces precisely, on the basis of considering both of precision and smoothness，a factor set of evaluation was determined.Using analytic hierarchy process(AHP) to determine weights of the evaluation factors, combining with fuzzy analysis and artificial neural network, the quality evaluation model of automobile surfaces was established. After training and testing, the results prove that the model is accurate.

Key words: body surface, smoothness, fuzzy comprehensive evaluation, artificial neural network
