Abstract
Purpose: To reduce the subjective prejudice and uncertainty in evaluating product quality. Design/methodology/approach: AHP method is used to analyze the structure of product quality evaluation problem and determine weights for evaluation criteria. After structure judge matrix, sequencing calculation and concordance examination, evaluation methods such as fuzzy synthesis evaluation are used to calculate the integrated quality evaluation result of each product. Findings: A new model is proposed by comprehensively using AHP method, weighted comprehensive evaluation and fuzzy comprehensive evaluation. A practical example of a product has been used to illustrate the theoretical qualitative proposed evaluation model. Practical implications: The result of this research offers a new method for the enterprises production quality management. Originality/value: Using AHP fuzzy comprehensive evaluation method in building product quality evaluation system.
Highlights
As the gradually improving of specialization level, more and more manufacturing enterprises start to purchase basic products parts manufactured by suppliers instead of producing all parts of the product by themselves
This study is to develop a scientific quality evaluation system which comprehensively applies Analytic Hierarchy Process (AHP) method, weighted comprehensive evaluation and fuzzy comprehensive evaluation, to convert subjective judgment into scientific decision-making result
The second contribution was a development of a multi-criteria decision model for evaluation and selection which is used for supplier selection
Summary
As the gradually improving of specialization level, more and more manufacturing enterprises start to purchase basic products parts manufactured by suppliers instead of producing all parts of the product by themselves. Bidding method and Delphi method are the most popular methods to select suppliers in Chinese enterprises at present (Shenghai, Hua & Ningsheng, 2005) These methods are qualitative, and, lack quantitative factors and are influenced by subjective factors greatly. This research is aimed at the characteristics of manufacturing products It applies AHP evaluation, weighted comprehensive evaluation and fuzzy comprehensive evaluation to the process of product quality comprehensive evaluation to design a product quality evaluation model which converts the subjective judgment into scientific decision-making result. It offers a new method for the enterprises production quality management
