Research on Evaluation and Decision-Making Model of Product Design Scheme Based on TFN-AHP-GRA
In view of (Considering)the fuzziness of attribute information in process of scheme design for electromechanical product emphasizing both form and function, the construction methods of evaluation index during evaluation and decision-making on the scheme is studied, the construction methods of evaluation index system based on technology, aesthetics, economy and society is proposed, and the comprehensive evaluation and decision-making model of product design scheme that integrates Analytical Hierarchy Process(AHP), Triangular Fuzzy Numbers(TFN),and Gray Relating Analyze (GRA) is established. With evaluating and decision-making on three electric hair dryer cases, the effectiveness of the model and method is demonstrated indirectly by the contrast between the result and the share of sales of three electric hair dryers on the market.
