改进选择绿色供应商的灰色关联方法

以灰色理论为基础,提出改进灰色关联方法,以加权灰色关联度和均衡度合成的均衡接近度作为评价准则,使得评价结果符合客观实际。建立机电产品的绿色供应商指标体系,明确按改进灰色关联方法选择绿色供应商的计算方法和步骤,为推广应用改进灰色关联方法奠定了基础。

Improved Grey Correlative Method for Green Supplier Selection

The improved grey correlative method was put forward on the basis of grey theory. Because balanced adjacent degree, which is derived from weighted grey correlative degree and balanced degree, was adopted as evaluation criteria in this method, the evaluation result is more adjacent to reality. The system of evaluation indices for green supplier selection was put forward based on mechanical and electrical products. The calculation method and procedure of the improved grey correlative method to select green suppliers were ascertained. This can provide a better basis to popularize this method.
