在回顾和分析供应商选择若干方法的基础上,针对该问题所具有的多目标评价的性质,提出了熵值法与TOPSIS法结合对战略供应商评价和排序的新方法。首先依据信息论中熵权原理计算各候选供应商的熵权值,然后用改进的TOPSIS法构造决策矩阵,最后给出了熵值法与TOPSIS法联合模型。通过建立战略供应商选择的指标体系进行决策,给出的实例计算表明了该方法的有效性和可行性,对核心企业选择战略供应商具有重要参考价值。
Based on the review and analysis of several methods of supplier selection, aiming at the nature of multi-objective evaluation of the problem, a new method combining entropy method and TOPSIS method to evaluate and sort the strategic suppliers is proposed. Firstly, the entropy weight of each candidate supplier is calculated according to the information entropy principle, and then the decision matrix is constructed by the improved TOPSIS method. Finally, the joint model of entropy method and TOPSIS method is given. Through establishing the index system of strategic supplier selection, the example calculation shows the effectiveness and feasibility of the method, which is of great value to the core enterprises in choosing strategic suppliers.
