TLDR
In this paper, the authors discuss recent work in developing scalar measures of inefficiency which comprehend all inefficiencies, including non-zero slacks, and are readily interpretable and easily used in a wide variety of contexts.About:

A Slacks Based Measure of Efficiency in Data Envelopment Analysis
TL;DR: A Slacks-Based measure of efficiency of efficiency in DEA that deals directly with the input surplus and the output shortage of the decision making unit (DMU) concerned and is unit invariant and monotone decreasing with respect toinput surplus and output shortage.

A slacks-based measure of super-efficiency in data envelopment analysis
TL;DR: This paper addresses the "super-efficiency" issue of Data Envelopment Analysis by using the slacks-based measure (SBM) of efficiency, which the author proposed in his previous paper [European Journal of Operational Research 130 (2001) 498].
A Slacks-based Measure of Super-Efficiency in Data Envelopment Analysis
TL;DR: In this paper, the slacks-based measure (SBM) of efficiency was proposed to discriminate the efficient decision making units (DMUs) based on the existence of slacks.

Evaluation of research in efficiency and productivity:a survey and analysis of the first 30 years of scholarly literature in DEA
TL;DR: An extensive, if not nearly complete, listing of DEA research covering theoretical developments as well as "real-world" applications from inception to the year 2007 is presented.
Journal ArticleDOI
Review of ranking methods in the data envelopment analysis context
TL;DR: No one methodology can be prescribed here as the complete solution to the question of ranking, as each technique is useful in a specialist area.

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.
