摘　　要：针对于产品全生命周期各个阶段影响质量因素的多层次、多因素相互联系又相互制约,而且具有明显的不确定性、模糊性,为了提高产品质量,提出了基于模糊层次分析法结合模糊综合评价的质量评价数学模型。此模型引入三角模糊数的一些基本理论,采用三角模糊数表征专家判断信息以充分考虑专家判断的模糊性;采用层次分析法对专家判断结果进行处理以得到这些质量影响因素的权重。最后,再结合模糊综合评价模型使所得产品质量评价结果更加科学、更加符合实际。并通过以重型机械制造企业的产品(磨煤机)为实例进行质量评价分析,验证了该产品质量评价模型的合理性和可靠性。Seeing that the influence quality factors of product life cycle 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） was 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 was used to make the results of product quality evaluation more scientific and effective. The product of some Heavy Machinery Enterprise （coal grinding mill） was introduced as an example to demonstrate the rationality and validity of the method.
