绿色供应链中基于改进的TOPSIS方法的供应商评价与选择

摘要

On the basis of green supply chain, the combing method of entropy weight method and improved TOPSIS method to choose green supplier is put forward. First builds green supplier evaluation index system, then adopts the entropy weight method to get the weight of each index, finally through an example, uses the traditional TOPSIS method and the improved TOPSIS method to choose the supplier respectively and compares the two methods. Results show that the improved TOPSIS method to choose the supplier is reasonable and feasible, and more scientific.%在绿色供应链基础上提出了一种基于熵权法与改进的TOPSIS法相结合的方法选择绿色供应商。首先构建绿色供应商的评价指标体系，然后采用熵权法得到各指标的权重。最后通过算例分别采用传统的TOPSIS方法和改进的TOPSIS方法选择供应商，并对2种方法及所得结果进行比较。结果表明，用改进的TOPSIS方法选择供应商是可行的、合理的，且更加科学。
