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

Predicting Japanese bank stock performance with a composite relative efficiency metric: A new investment tool
Necmi K. Avkiran,Hiroshi Morita +1 more
TL;DR: In this paper, a composite efficiency metric from relative contextual financial analysis is used to predict bank stock performance one year ahead with a composite metric from a composite of financial ratios, generalized data envelopment analysis and simulated annealing.

DEA advanced models for geometric evaluation of used lathes
João Carlos Correia Baptista Soares de Mello,Eliane Gonçalves Gomes,Lidia Angulo Meza,Fabiana Rodrigues Leta +3 more
TL;DR: In this paper, a preliminary study of the quality of lathes using Data Envelopment Analysis (DEA) as a multicriteria tool is presented, which aggregate several measurements that show geometrical errors to obtain one single measurement that will be free of subjective opinions.

Benchmarking urban energy efficiency in the UK
TL;DR: In this article, the authors compared three methods: ratio measures, regression residuals, and data envelopment analysis, and found that each method has its own strengths and weaknesses regarding the ease of interpretation, ability to identify outliers and provide consistent rankings.
Hospital performance evaluation in Uganda: a super efficiency data envelope analysis model
TL;DR: In this article, the authors measured the technical efficiency of 25 district referral hospitals from three regions of Uganda over the 1999-2003 period and applied a super-efficiency Data Envelopment Analysis model.

Integrated bank performance assessment and management planning using hybrid minimax reference point - DEA approach
Jian-Bo Yang,Jian-Bo Yang,Brandon Yu Han Wong,Dong-Ling Xu,Dong-Ling Xu,Xin-Bao Liu,Ralph E. Steuer +6 more
TL;DR: The HMRP-DEA approach is investigated to incorporate the value judgements of both branch managers and head-office directors and to search for the most preferred solution along the efficient frontier for each bank branch, which provides the unprecedented insight into integrated efficiency and trade-off analyses.

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.
