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

Urban transportation in Chinese cities: An efficiency assessment
TL;DR: In this article, the authors used 2008 data for 34 Chinese cities to compare urban transportation systems and found that cities with more sustainable transportation are also more likely to have lower gross domestic product per capita, be smaller, are less urbanized and have higher bus usage.

Is data envelopment analysis a suitable tool for performance measurement and benchmarking in non-production contexts?
TL;DR: In this paper, the authors systematically investigated strengths and weaknesses of data envelopment analysis (DEA) in the case of welfare evaluation using real data on 27 countries of the European Union and analyzed the differences in the results of various frequently used DEA models for two different but strongly connected sets of welfare indicators.

A hybrid approach using two-level DEA for financial failure prediction and integrated SE-DEA and GCA for indicators selection
Chao Huang,Chong Dai,Miao Guo +2 more
TL;DR: A new data envelopment analysis (DEA) model that is a two-level DEA as a quick and feasible tool for corporate financial failure prediction, which is able to handle quite a large number of inputs and outputs by utilizing hierarchical structures of financial indicators.

Unified Efficiency Measurement of Electric Power Supply Companies in China
TL;DR: In this article, the authors measured the economic and unified efficiency of 24 electric power supply companies in China and combined the unified efficiency data envelopment analysis (DEA) model and the super-efficiency DEA model to create a USDEA model, calculating companies' unified efficiency.

An integrated fuzzy simulation–fuzzy data envelopment analysis approach for optimum maintenance planning
TL;DR: An integrated fuzzy simulation–fuzzy data envelopment analysis (FSFDEA) to cope with a special case of ‘maintenance activity planning’ problem and would help managers to identify the preferred strategy considering and investigating various parameters and scenarios.

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.
