面向大型煤炭企业的物资供应商评价与选择研究
发布时间：2018-09-06 15:08
【摘要】：由于大型煤炭企业对物资需求和安全生产要求的特殊性,其在物资供应商的选择上更加审慎。文章综合考虑大型煤炭企业在物资供应商评价与选择过程中的模糊性、群体性及多阶段等特点,提出一种基于模糊多属性群决策的多阶段供应商评价与选择模型。该模型利用熵方法确定指标客观权重,运用扩展的TOPSIS方法确定评价人员权重,并引入对数增长模型确定阶段权重,进而利用集结算子和期望值函数得到供应商的综合排序结果,从而实现物资供应商的优化选择。
[Abstract]:Because of the particularity of material demand and safety in production, large coal enterprises are more cautious in the selection of material suppliers. Considering the characteristics of fuzziness, group and multi-stage in the process of material supplier evaluation and selection in large coal enterprises, a multi-stage supplier evaluation and selection model based on fuzzy multi-attribute group decision is proposed in this paper. In this model, the objective weight of the index is determined by entropy method, and the weight of evaluator is determined by the extended TOPSIS method. The logarithmic growth model is introduced to determine the weight of the stage, and then the aggregate operator and the expected value function are used to obtain the comprehensive ranking result of the supplier. In order to achieve the optimal selection of material suppliers.
