摘　　要：结合数据包络分析(DEA)方法和相对势模型,提出了一种评价多个电能计量装置改造项目综合效益的方法。该方法在建立好评价指标体系的基础上,利用DEA模型对待评项目的有效性进行初步评价,并对无效率的改造项目作投影分析;运用相对势模型对各电力部门未实施计量装置改造项目时的状态进行二次评价,分别计算出综合相对势并排序比较;通过对两次评价结果的评判和分析找出真正效率低下的改造项目,提出相应的改进方向和途径。实例的评价过程及结果证明了该方法的可行性和有效性。A new method for post-evaluation of a project of rebuilding electric energy measuring devices is proposed using data envelopment analysis （DEA） and relative potential model. Based on setting up an index system, EDA is employed to evaluate the effectiveness of projects and to analyze projection for ineffective projects. The relative potential model is used to evaluate the state of all electric power departments before the project is implemented. The comprehensive relative potential for each is calculated respectively and compared. It is demonstrated that the method is feasible and useful.
