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

Output complexity, environmental conditions, and the efficiency of municipalities: a robust metafrontier approach
TL;DR: In this article, the authors propose a metafrontier analysis in which the efficiency of municipalities is evaluated after splitting them into clusters according to various criteria (output mix, environmental conditions, size).

Cross-ranking of Decision Making Units in Data Envelopment Analysis
TL;DR: In this article, the cross-efficiency matrix is converted to a cross-ranking matrix, which is then used to rank the decision-making units based on the ranking order of the matrix.

Beyond Travel & Tourism competitiveness ranking using DEA, GST, ANN and Borda count
TL;DR: A solution that involves applying a variety of objective weighting methods, including data envelopment analysis (DEA), grey system theory (GST), and artificial neural network (ANN), to produce sensible rankings is proposed, as well as employing Borda count methodology to merge these rankings.

A note on DEA efficiency assessment using ideal point: An improvement of Wang and Luo’s model
TL;DR: This paper slightly revised the models so that a DEA analysis using TOPSIS idea can be performed and finds that their approach is problematic in employing the negative ideal point (NIP) for DEA computation.

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.
