Sampling size and efficiency bias in data envelopment analysis
In Data Envelopment Analysis when the number of decision making units is small the number of units of the dominant or e cient set is relatively large and the average e ciency is generally high The high average e ciency is the result of assuming that the units in the e cient set are e cient If this assumption is not valid this results in an overestimation of the e ciencies which will be larger f...
متن کاملTotal and Partial efficiency indexes in data envelopment analysis
Introduction: Data envelopment analysis (DEA) is a data-oriented method for measuring and benchmarking the relative efficiency of peer decision making units (DMUs) with multiple inputs and multiple outputs. DEA was initiated in 1978 when Charnes, Cooper and Rhodes (CCR) demonstrated how to change a fractional linear measure of efficiency into a linear programming format. This non-parametric app...
متن کاملRobust efficiency in data envelopment analysis with VRS technology
One of the fundamental problems in the classic DEA is lack of ability to distinguish unit's performance scores that is considered as a disadvantage. Recently, Parkan et al. [9] tried to address this problem. They proposed to assess each unit both optimistic and pessimistic views are taken into account. In contrast to traditional evaluation, one index is considered for each unit based on the l...
متن کاملCost Efficiency Measures In Data Envelopment Analysis With Nonhomogeneous DMUs
In the conventional data envelopment analysis (DEA), it is assumed that all decision making units (DMUs) using the same input and output measures, means that DMUs are homogeneous. In some settings, however, this usual assumption of DEA might be violated. A related problem is the problem of textit{missing} textit{data} where a DMU produces a certain output or consumes a certain input but the val...
متن کاملEfficiency of Centralized Structures in Data Envelopment Analysis Ratio Models
This paper investigates the centralized resource allocation with centralized structures by using the data envelopment analysis-ratio (DEA-R) models. To this end, it proposes a method to determine the resource allocation of centralized structures such that the ratio of inputs to outputs are minimized.
