摘要： 以提高产品质量为出发点,深入分析了产品广义质量的内涵,建立了产品广义质量模糊评价的目标体系,即包含有结构性能、工作性能和工艺性能在内的产品全性能和全功能的综合指标体系,而且较全面地考虑了产品广义质量的层次性和复杂性.采用熵权与主观权重相结合的方法来确定各个评价指标的权重值,使产品质量评价更具客观性和科学性.与模糊综合评价法相比,该方法克服了凭经验确定指标权重的主观性,增强了权重的可信性,评价结果具有较高的可信度.

Abstract: With a view to improving product quality, the concept of generalized product quality is proposed and analyzed in depth to frame a comprehensive fuzzy evaluation system for product quality, which includes all the constructional, operational and technological performance and functions and takes account of the hierarchy and complexity of such an evaluation system. In the system the weighted value for each and every evaluation index is determined by combining the entropy weight with subjective weight so as to make the evaluation more objective and scientific. Compared with the method of comprehensive fuzzy evaluation, the evaluation system thus framed gets rid of the empirical subjectivity in determining index weight, thus enhancing the dependability of the weight and, as a result, such an evaluation will be more reliable.
