TLDR
Two models are proposed to evaluate the performance of this type general two-stage network structures where all outputs of the first stage are the only inputs to the second stage, and a non-cooperative model, in which one of the stages is regarded as the leader and the other is the follower.Abstract:
This chapter discusses DEA modeling technique for a two-stage network process where the inputs of the second stage include both the outputs from the first stage and additional inputs to the second stage. Two models are proposed to evaluate the performance of this type two-stage network structures. One is a non-linear centralized model whose global optimal solutions can be estimated using a heuristic search procedure. The other is a non-cooperative model, in which one of the stages is regarded as the leader and the other is the follower. The newly developed models are illustrated with a case of regional R&D of China.read more

Efficiency Bounds for Two-Stage Production Systems
TL;DR: The Salo and Punkka (2011) model is extended to a more common and practical case considering the two-stage production structure as well as efficiency bounds for each subsystem/substage and an application for nonlife insurance companies has been discussed to illustrate the applicability and show the usefulness of this method.

Provincial production and pollution treatment performance in China based on a two-stage eco-inefficiency approach with undesirable intermediate outputs
TL;DR: Li et al. as mentioned in this paper proposed a new data envelopment analysis (DEA) approach for measuring the eco-inefficiency of two-stage structures with undesirable intermediate measures, and then applied the approach to 30 Chinese provincial regions with production and pollution treatment activities.

A compositional approach to two-stage Data Envelopment Analysis in intuitionistic fuzzy environment
TL;DR: In this article, the authors present a model of two-stage network data envelopment analysis based on intuitionistic fuzzy data, which measures the efficiency of the first and second stages of each DMU, and ultimately the overall efficiency measures based on the stage efficiencies.

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.

Efficiency and cross-efficiency in DEA: derivations, meanings and uses
John R. Doyle,Rodney H. Green +1 more
TL;DR: A neglected aspect of Data Envelopment Analysis: cross-efficiency is examined, and an intuitive understanding of cross- efficiency is ground in the concept of peer-appraisal, as opposed to self-appRAisal implied by simple efficiency.

TL;DR: A slacks-based network DEA model is proposed, called Network SBM, that can deal with intermediate products formally and evaluate divisional efficiencies along with the overall efficiency of decision making units (DMUs).
