Output–input ratio analysis and DEA frontier
Yao Chen,Agha Iqbal Ali +1 more
TLDR
It is shown that top-ranked performance by ratio analysis is a DEA frontier point, which allows identification of membership of frontier DMUs without solving a DEA program.About:

Performance evaluation of participating nations at the 2012 London Summer Olympics by a two-stage data envelopment analysis
TL;DR: The efficiency of each participating nation in the entire two-stage Olympic process is calculated as a product of the efficiencies of both stages, and a heuristic search is applied to the extended relational model.

A robust nonparametric approach to the analysis of scientific productivity
Andrea Bonaccorsi,Cinzia Daraio +1 more
TL;DR: Nonparametric envelopment techniques were used, and robust nonparametric techniques were applied in this work for the first time for evaluating scientific productivity, and they are shown to be useful tools to compute scientific productivity indicators and make institutional comparative analyses.

An effective total ranking model for a ranked voting system
A. A. Foroughi,Mehrdad Tamiz +1 more
TL;DR: An effective model to rank candidates in a preferential election is proposed that is an extension and simplified form of a recently proposed model for ranking efficient candidates and can be used for ranking inefficient as well as efficient candidates.

Using the DEA-R model in the hospital industry to study the pseudo-inefficiency problem
TL;DR: This study puts forward the DEA-R-I as a capable substitutive model for CCR-I in order to avoid pseudo-inefficiency and proved that it is a valid model.
Journal ArticleDOI
Cost and revenue efficiency in DEA-R models
TL;DR: This paper aims to create models for the estimation of cost and revenue efficiency, with particular attention being paid to ratio DEA (DEA-R) models, which eliminates some of the disadvantages associated with standard DEA models.

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.

Components of efficiency evaluation in data envelopment analysis
TL;DR: In this paper, the authors examine three essential components which comprise efficiency evaluation in data envelopment analysis and determine the implicit evaluation scheme associated with the model and provide a framework for classifying the various DEA models with respect to (i) the form of envelopment surface, (ii) the orientation, and (iii) the pricing mechanism implicit in the multiplier lower bounds.

Streamlined computation for data envelopment analysis
TL;DR: Computational testing with real-world data sets with up to 533 decision making units indicates that employing constructs that facilitate efficiency of computation in solving a sequence of as many linear programs as there are decisionMaking units reduces computation time significantly.
