质量损失成本主要影响因素分析及其自然权重模型的建立

文章主要讨论了质量损失成本各主要影响因素,并根据自然权重理论建立了各因素的自然权重计算模型.首先分析了影响质量损失成本的主要影响因素分为人为因素和机械设备因素两部分,人为因素包括质量体系的维护与实施、供应商的评价与维护、产品检验与过程控制、市场调研和员工操作；机械设备因素包括设备突发事故等.然后,利用自然权重理论,根据其具有模糊属性的性质,依据各影响因素的不同特性,讨论各影响因素的函数曲线,并在考虑到不同产品下的影响因素的影响程度也不同,为各影响因素添加了校正系数,从而建立了适用于各产品讨论的质量损失成本各影响因素的隶属函数.最后,根据所建立的隶属函数,依据自然权重定义,建立了各影响因素的自然权重计算模型.

Research on the Key Factors of Failure Quality Cost and its Natural Weight Model

This paper analyzes the main influential factors of the quality failure cost,and according to the natural weight theo ry,the paper establishes the mathematical model.Firstly,the paper analyzes the main influential factors,including the hu man factors and the equipment factors.The human factors are consist of the maintenance and the application of the quality management system,the evaluation and the maintenance of the suppliers,the product test and the process control,the mar ket investigation and the workers’ operation.Equipment factors mean that the problems caused by the equipment.Then by taking use of the natural weight theory and according to the fuzzy property and the different attribute of different factors,the pa per discusses the functional curves of the influential factors,and considering the different influential extent to different prod ucts,the paper adds a correction coefficient,in order to establish a membership function that is suitable to every product.Fi nally,based on the membership function,and according to the definition of the natural weight,the paper establishes the natu ral weight mathematical model of the factors.
