基于中智犹豫模糊语言优先QUALIFLEX方法的绿色供应商选择

针对绿色供应商选择过程中,评价指标数量明显超过可供选择的供应商数量且指标之间存在优序关系等特点,提出了基于中智犹豫模糊语言优先QUALIFLEX方法的绿色供应商选择方法.首先,利用中智犹豫模糊语言表征评价信息和评价权重;其次,构造优先矩阵对指标权重做精确化处理,考虑到决策者对指标的要求和指标之间的优序关系,对指标权重进行修订;然后,提出改进的中智犹豫模糊语言余弦距离测度,在此基础上借助QUALIFLEX方法确定备选供应商的最终排序;最后,利用化学制药企业选择原料供应商的案例验证了所提方法的有效性.

Green Supplier Selection Based on Neutrosophic Hesitant Fuzzy Linguistic Prioritized QUALIFLEX Method

In the process of green supplier selection,the numbers of evaluation attributes obviously exceeds the number of available suppliers,and there is a priority order relationship among attributes,the neutrosophic hesitant fuzzy linguistic prioritized QUALIFLEX method is proposed to solve the problem of green supplier selection.Firstly,the neutrosophic hesitant fuzzy linguistic set was used to represent the evaluation information and evaluation weights.Secondly,a priority matric is constructed to precisely the attribute weights.Considering the requirements of decision makers on the evaluation attributes and the ordering relationship between the attributes,the weights are revised.Then,an improved neutrosophic hesitant fuzzy language cosine distance measure is proposed,and the QUALIFLEX method was used to determine the ranking of alternative suppliers.Finally,a case of chemical and pharmaceutical companies to select raw material suppliers is used to verify the effectiveness of the proposed method.
