Comprehensive Quality Evaluation Oriented to Product Lifecycle

Abstract:

Seeing that the influence quality factors of product lifecycle are multi-object, multi-level, interconnection and interaction, which possess uncertainty and fuzziness obviously, in order to product quality, quality evaluation mathematical model based on Fuzzy Analytical Hierarchy Process (FAHP) and Fuzzy Comprehensive Evaluation (FCE) is proposed to evaluate product quality. This method introduced the triangular fuzzy number to represent experts’ judgment information of product quality and used the AHP to rank these influence quality factors. At last, FCE is used to make the results of product quality evaluation more scientific and effective. The product of some Heavy Machinery Enterprise (coal grinding mill) is introduced as an example to demonstrate the rationality and validity of the method.
