摘　　要：基于采购企业经常向多家供应商采购的实际需要,本文研究了存在供应能力约束的多源采购决策问题。其决策过程分2步进行:第1步运用群组AHP法、聚类分析法确定属性主观权重,运用熵值模型确定属性客观权重,并将属性主观权重和客观权重线性加权拟合成属性综合权重,通过TOPSIS方法对供应商进行排序;第2步对初步入选的供应商,考虑供应能力约束,建立多目标规划模型,确定采购数量在各个供应商间的最优分配。最后通过具体实例给出该方法的决策过程。Considering the purchasing company＇s needs for multiple suppliers, this paper researchs multi-sourcing procurement decision-making problem. The decision-making process is divided into two steps. First of all, using the group AHP method, cluster analysis method determine subjective weights of attribute, using entropy model determine objective weight of attribute, and they are synthesized comprehensive weight by linear weighting, and the suppliers＇ order is obtained according to the technique for preference by similarity to ideal solution model. Then a multi-objective planning model is constructed to identify the allocation of the procurement number between selected suppliers. Finally, a specific example is given to demonstrate the decision-making process of the method.
