摘要: 通过分析和总结供应链环境下战略供应商评价选择的准则、指标和方法,以供应链核心企业选择战略性供应商为目标,提出了战略性供应商评价的指标体系。研究了一种新的DEA模型,首先利用熵权法为各指标确定一个权重,然后利用线性加权方法将其与C2R模型的自由权重合成生成综合权重,并使用DEA/TOPSIS联合方法解决供应商选择问题,克服了DEA法与TOPSIS法单独应用时各自存在的不足。实证分析证明了该模型及方法的有效性,并为重视熵权的DEA/TOPSIS联合法在多目标规划中的运用提供了依据与参考。

Abstract: It is important for a manufacture to select appropriate suppliers and the supplier selection problem is a multi-objective optimization problem. A method called technique for order preference by similarity to idea solution (TOPSIS) is often used to solve this problem. However, by using TOPSIS, it is difficult to find the weights to obtain a good solution. In this paper, a system of evaluation indices for supplier selection is put forward. Then, a model called DEA/TOPSIS that combines TOPSIS with DEA is presented. By determining the entropy weight of each index, a combined entropy-DEA weight method is proposed. In this way, subjectivity can be avoided to some extent. The proposed method is applied to a ultra-white glass manufacturing enterprise for supplier selection and a satisfied result is obtained.
