A distance-based measure of super efficiency in data envelopment analysis: an application to gas companies
نویسندگان
چکیده
Conventional data envelopment analysis (DEA) assists decision makers in distinguishing between efficient and inefficient decision making units (DMUs) in a homogeneous group. However, DEA does not provide more information about efficient units. Super-efficiency DEA models can be used in ranking the performance of efficient DMUs. This research proposes a methodology to determine an Euclidean distance-based measure of super-efficiency. Then, the DMUs are ranked according to their super-efficiency score. The applicability of the proposed model is illustrated in the context of the analysis of gas companies performance.

متن کاملA novel radial super-efficiency DEA model handling negative data
Super-efficiency model in the presence of negative data is a relatively neglected issue in the DEA field. The existing super-efficiency models have some shortcomings in practice. In this paper, a novel VRS radial super-efficiency DEA model based on Directional Distance Function (DDF) is proposed to provide a complete ranking order of units (including efficient and inefficient ones). The propose...
متن کاملThe directional hybrid measure of efficiency in data envelopment analysis
The efficiency measurement is a subject of great interest. The majority of studies on DEA models have been carried out using radial or non-radial approaches regarding the application of DEA for the efficiency measurement. This paper, based on the directional distance function, proposes a new generalized hybrid measure of efficiency under generalized returns to scale with the existence of both r...
