TLDR
In this paper, a modified version of DEA based upon comparison of efficient DMUs relative to a reference technology spanned by all other units is developed, which provides a framework for ranking efficient units and facilitates comparison with rankings based on parametric methods.Abstract:
Data Envelopment Analysis DEA evaluates the relative efficiency of decision-making units DMUs but does not allow for a ranking of the efficient units themselves. A modified version of DEA based upon comparison of efficient DMUs relative to a reference technology spanned by all other units is developed. The procedure provides a framework for ranking efficient units and facilitates comparison with rankings based on parametric methods.read more

Modified MAJ model for ranking decision making units in data envelopment analysis
TL;DR: The technique used for rendering this model unit-invariant causes the ranking to change when some inputs of some inefficient DMUs change, without causing any change in the new PPS.

Technology forecasting using data envelopment analysis
TL;DR: In this article, the authors proposed a new method to address the shortcomings of common forecasting techniques by extending a well-established management science methodology known as data envelopment analysis (DEA).

Ranking of decision making units in data envelopment analysis: A distance-based approach
TL;DR: A new DEA ranking approach that uses L"2-norm is described, where the difficulties of the existing methods have been removed and the methods for ranking efficient units are described.

State road transport undertakings in India: technical efficiency and its determinants
TL;DR: In this article, three popular data envelopment analysis (DEA) models, namely CCR, BCC and Andersen and Petersen's super efficiency models, have been utilized to compute various efficiency scores for individual SRTUs.

TL;DR: Broader DEA application might characterize OR efficiency more informatively than conventional single-ratio rank ordering, suggesting whether patient flow might be efficiently further increased through these sites.

Measuring the efficiency of decision making units
TL;DR: A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs and methods for objectively determining weights by reference to the observational data for the multiple outputs and multiple inputs that characterize such programs.

Some Models for Estimating Technical and Scale Inefficiencies in Data Envelopment Analysis
TL;DR: The CCR ratio form introduced by Charnes, Cooper and Rhodes, as part of their Data Envelopment Analysis approach, comprehends both technical and scale inefficiencies via the optimal value of the ratio form, as obtained directly from the data without requiring a priori specification of weights and/or explicit delineation of assumed functional forms of relations between inputs and outputs as mentioned in this paper.

Measuring the technical efficiency of production
Rolf Färe,C. A. Knox Lovell +1 more
TL;DR: The purpose of this paper is to specify a set of properties such an efficiency measure should satisfy, to show that the widely used measure proposed by Farrell does not satisfy them, and to introduce a new measure that does satisfy these properties.

Polyhedral Cone-Ratio DEA Models with an illustrative application to large commercial banks
TL;DR: Polyhedral Cone-Ratio Data Envelopment Analysis Models generalizing the CCR Ratio Model are developed for situations with a finite number of DMUs and employing polyhedral cones of virtual multipliers as discussed by the authors.
