Assessing the performance of distribution lines based on data envelopment analysis

This paper proposes a quantificational assessment method to explore the performance of distribution lines based on data envelopment analysis (DEA). In this method the input and output factors are set from the viewpoint of input-output and the utilization efficiency of these distribution lines is calculated and evaluated by DEA, and empirical results are: the utilization efficiency of these distribution lines, the gaps between realism and optimal conditions of inefficient lines, the population distribution of technical efficiency and redundant statistics of input factors. Based on these results, the decision-makers can adopt pertinent measures to improve distribution line situation, meanwhile these results can be used for reference of policy-making in distribution investments and tariff structure.
