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

The Measurement of Efficiency in Portuguese Hotels Using Data Envelopment Analysis
TL;DR: In this paper, the economic efficiency of a sample of Portuguese hotels for the period 1998-2002 is analyzed with data envelopment analysis, and the efficiency scores of the hotels analyzed are decomposed into technical and allocative efficiency by using outputs, inputs and input prices.

Improving the discrimination power and weights dispersion in the data envelopment analysis
TL;DR: Two new models based on a multi-criteria data envelopment analysis (MCDEA) are developed to moderate the homogeneity of weights distribution by using goal programming (GP).

Malmquist Productivity Index
TL;DR: The Malmquist index (MI) as discussed by the authors evaluates the efficiency change over time, measured as the product of catch-up (or recovery) and frontier shift (or innovation) terms, both coming from the DEA technologies.
Journal ArticleDOI
Cross-efficiency evaluation based on ideal and anti-ideal decision making units
TL;DR: The new DEA models determine input and output weights from the point of view of distance from IDMU or ADMU without the need to be aggressive or benevolent to any DMUs, resulting in cross-efficiencies that are neutral and more logical.

A note on "A methodology for supply base optimization"
Srinivas Talluri,Ram Narasimhan +1 more
TL;DR: In this article, the authors developed a quantitative methodology for supply base optimization, which involves reconfiguring the buying firm's supply base by evaluating and selecting potential suppliers with respect to the strengths of existing suppliers and excluding underperforming suppliers from the firm's supplier base.

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.
