Data Envelopment Analysis Applied to Electricity Distribution Districts
用数据包络分析评估希腊公共电力公司45个配送区域的效率，并与简单生产率指标和计量方法比较，发现DEA更可靠，低效率原因包括管理、系统设计或环境因素。
In this paper Data Envelopment Analysis (DEA) is used to evaluate efficiency measures for the 45 distribution districts of the Greek Public Power Corporation (PPC). Results are derived under different sets of assumptions and are compared with simple productivity indices used by PPC and with efficiency measures produced by econometric methods. DEA scores appear to be more reliable than simple productivity indices. Comparison of the different cases explains the reason for the low efficiencies, which can be due to the management of controllable inputs, the design of the supply system or other environmental factors.
