TLDR
This chapter discusses the basic DEA models and some of their extensions, which have been successfully applied to a host of many different types of entities engaged in a wide variety of activities in many contexts worldwide.Abstract:
In about 30 years, Data Envelopment Analysis (DEA) has grown into a powerful quantitative, analytical tool for measuring and evaluating the performance. DEA has been successfully applied to a host of many different types of entities engaged in a wide variety of activities in many contexts worldwide. This chapter discusses the basic DEA models and some of their extensions.read more

Evaluation of clustering algorithms for financial risk analysis using MCDM methods
Gang Kou,Yi Peng,Guoxun Wang +2 more
TL;DR: An MCDM-based approach to rank a selection of popular clustering algorithms in the domain of financial risk analysis and indicates that the repeated-bisection method leads to good 2-way clustering solutions on the selected financial risk data sets.

Network DEA: Additive efficiency decomposition
TL;DR: The overall efficiency of a structure is represented as an additive weighted average of the efficiencies of the individual components or stages that make up that structure, and the model allows one to evaluate not only the overall performance of the network, but as well represent how that performance decomposes into measures for theindividual components of thenetwork.

Social and financial efficiency of Islamic microfinance institutions:a Data Envelopment Analysis application
Indra Widiarto,Ali Emrouznejad +1 more
TL;DR: In this paper, the authors proposed a two-stage analysis to measure Islamic Microfinance institutions (IMFIs) performance by comparing them to conventional MFIs and identified factors that contribute to the efficiency of IMFIs and MFIs.

Measuring eco-efficiency of wheat production in Japan: a combined application of life cycle assessment and data envelopment analysis
TL;DR: In this paper, the authors measured the eco-efficiency of wheat production in Japan at a regional scale using a combined methodology of life cycle assessment and data envelopment analysis, and found that wheat production can occur in both good and poor growing conditions, with a wheat yield obtained by an adequate application of nitrogen fertilizer.

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.

Data Envelopment Analysis: A Comprehensive Text with Models, Applications, References and DEA-Solver Software
TL;DR: In this article, the basic CCR model and DEA models with restricted multipliers are discussed. But they do not consider the effect of non-discretionary and categorical variables.

Theory of cost and production functions
TL;DR: In this article, a unified treatment of cost and production functions underlie the economic theory of production is presented, and the duality between cost function and production function is developed by introducing a cost correspondence, showing that these two functions are given in terms of each other by dual minimum problems.
