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

Supplier selection problem revisited from the perspective of product configuration
Duck Young Kim,Stephan M. Wagner +1 more
TL;DR: The supplier selection problem from the perspective of product configuration is addressed and the need to consider interrelationships between suppliers, namely, supplier–supplier relationships during the selection process of the combination of suppliers is highlighted.

Objective measurement of efficiency: applying single price model to rank hospital activities
TL;DR: The previous version of the model is reformed in critical aspects, extended and applied to a case of 27 hospital units with real world information on two inputs and four outputs and the axiomatic basis is reduced to a single assumption.

The environmental efficiency of Wanjiang demonstration area: A Bayesian estimation approach
Malin Song,Youyi Guan +1 more
TL;DR: In this article, the authors measured the environmental efficiency of the demonstration area, and then analyzed the total factor productivity of the area by Malmquist productivity index through data envelopment analysis (DEA) approach.

Developing a two-stage approach of super efficiency slack-based measure in the presence of non-discretionary factors and mixed integer-valued data envelopment analysis
TL;DR: A two-stage approach of super efficiency slack-based measure in non-discretionary factors and mixed integer requirements in which new factors and requirements were first integrated into the existing approach and the optimal solution was obtained.

How to Assess Sustainability of Suppliers in the Presence of Dual-Role Factor and Volume Discounts? A Data Envelopment Analysis Approach
TL;DR: A new super-efficiency method for evaluating sustainability of suppliers in the presence of dual-role factors and volume discounts is proposed and it is shown that enhanced Russell model (ERM) fails to present a complete ranking of suppliers.

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.
