The Appearance Of The Product Design Quality And Aesthetic Evaluation Of Theories And Research

In Computer Aided Industrial Design (CAID), evaluation to the quality of product's appearance and form is a matter about esthetics principle. It determines the nature but is difficult to measurable about art's domain. A good method to evaluate the quality of product's appearance impersonally and exactly is very needed.Based on the above, the following main problems are discussed in the dissertation.l.This paper puts forward a comprehensive evaluation method, which is based on analytic hierarchy process and fuzzy evaluation.2.Detailed analysis of the relation between the appearance and form of products and aesthetics' principle, and the research on the principles of the comprehensive evaluation establishment. Finally to present the very appropriate evaluation indexes of every class.3. Establishment of the hierarchy model of the comprehensive aesthetic evaluation system. This paper used the Analytical Hierarchy Process (AHP) to confirm the main factors and weight numbers, which influence the evaluation to the quality of product's appearance. Constructing the judging matrix, and to calculate every index's weight. This method solves the problem of combination between qualitative and quantitative evaluation existing in the original method to transfer the qualitative evaluation to the quantitative one, thus makes the evaluation method more comprehensive, rational, and scientific. The structure of evaluation indexes oriented to products on designing stage is established. Finally to get the result of the comprehensive evaluation using the linearity-weighted-sum method.4. An example that used the above method to evaluate the electromotive bicycle was presented. This approach was easy to operate, short cut and practical. Papers discussed the means and technology of a prototype system of the aesthetic evaluation of the products. The system will be a part of Computer Aided Industrial Design System.
