TLDR
The current paper develops an additive efficiency decomposition approach wherein the overall efficiency is expressed as a (weighted) sum of the efficiencies of the individual stages and can be applied under both CRS and variable returns to scale (VRS) assumptions.About:

Fair efficiency decomposition in network DEA: A compromise programming approach
Gregory Koronakos,Gregory Koronakos,Dimitris Sotiros,Dimitris K. Despotis,Manolis N. Kritikos +4 more
TL;DR: The proposed approach is novel in the sense that the obtained efficiency decomposition represents a fair compromise between the stages, as it is as close as possible to the maximum efficiency score and as far away as possible from the minimum efficiency score attained by each stage.

On network two stages variable returns to scale Dea models
TL;DR: In this paper, multiplicative decomposition of stages indices is shown to be consistent with V rs network technologies and the primal dual correspondence breaks for serial network V rs models within the network.

Measuring the efficiency of network structures: Link control approach
Amir Hassanzadeh,Amin Mostafaee +1 more
TL;DR: The way intermediate products affect overall and stage efficiency scores of units in different scenarios is examined and a supply chain of soft drink producer has been used to show the reasonableness and applicability of the proposed method.

Subsampling bootstrap in network DEA
TL;DR: In this paper , the authors examined the applicability of the subsampling bootstrap procedure in the approximation of the asymptotic distribution of the DEA estimator when the production process has a network structure, and in the presence of undesirable factors.
Journal ArticleDOI
Efficiency evaluation of a two-stage production process with feedback: an improved DEA model
TL;DR: Zhang et al. as mentioned in this paper explored the additive decomposition method in which the overall efficiency is a weighted average of the two stage efficiencies in a feedback system and found that the weight of the first stage is never less than that of the second stage.

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.

Efficiency decomposition in two-stage data envelopment analysis: an application to non-life insurance companies in taiwan
Chiang Kao,Shiuh-Nan Hwang +1 more
TL;DR: The relational model developed in this paper is more reliable in measuring the efficiencies and consequently is capable of identifying the causes of inefficiency more accurately.

Profitability and Marketability of the Top 55 U.S. Commercial Banks
Lawrence M. Seiford,Joe Zhu +1 more
TL;DR: In this article, the authors examined the performance of the top 55 U.S. commercial banks via a two-stage production process that separates profitability and marketability and uncovered substantial performance inefficiency in both dimensions.
