基于隶属度转换算法的绿色供应链绩效评价

为了改进绿色供应链中的不足,提高绩效水平,采用隶属度转换算法进行评价。在构建绿色供应链绩效评价指标体系的基础上,利用已知的一级指标、二级指标的重要性权重和隶属度向量,通过信息熵对各指标隶属度进行数据挖掘,并引入有效值和可比值实现不同指标的可比性,完成二级指标到一级指标、一级指标到绿色供应链绩效评价总目标的绩效评价。对广州市某电子产品企业的绿色供应链进行评价,结果表明其绩效水平达到第二等级＂良＂,另外通过置信度识别准别发现其供应链管理水平和信息技术水平对整体绩效的贡献率较低,还有待提高。

Performance evaluation of the green supply chain based on membership conversion algorithm

The performance of the green supply chain was evaluated with the conversion algorithm of membership to improve the shortage of green supply chain and improve performance leve.The author firstly founded a set of green supply chain performance evaluation index system,and mined the data hidden in the membership degree of each index with entropy according to the membership and weight of indicators already known,then introduced the effective value and the comparable value to achieve comparability,and finally finished the evaluation of the green supply chain from the second-grade indexes to the first-grade indexes,and the first-grade indexes to the overall goal.The performance of the green supply chain of an electronic company in Guangzhou was evaluated,and the results showed that the green supply chain performance level of the electronics company achieved the second-grade level ＂good＂,and the contribution of the supply chain management level and the information technology level to the overall performance was low and remained to be improved.
