为评价低碳背景下发电上市企业运营效率,将低碳化指标引入发电企业运营效率评价指标体系中,构建了兼容发电生产、经营管理、低碳发展三方面的新型指标体系;针对传统数据包络分析(DEA)模型易受数据极值影响、未区分指标正负向等缺点,构建了改进的DEA模型,并提出用鞍点算法求解。实例应用表明,所提方法精度较高、可操作性强,具有一定推广价值。
In order to evaluate the operating efficiency of power generation listed companies under low-carbon environment, the low-carbon indicators are introduced into the evaluation index system of power generation enterprises operational efficiency, and a new index system compatible with power generation production, operation and management and low-carbon development is constructed. According to the traditional data envelopment Analysis (DEA) model is vulnerable to the data extreme value, the distinction between the positive and negative indicators and other shortcomings, to build an improved DEA model, and proposed using saddle point algorithm to solve. The example application shows that the proposed method has higher accuracy and operability, and has some promotion value.
