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

Network DEA pitfalls: Divisional efficiency and frontier projection under general network structures
TL;DR: It is demonstrated that under general network structures, the multiplier and envelopment network DEA models are two different approaches and the envelopment model’s divisional efficiency may actually be the overall efficiency.

Two-stage network processes with shared resources and resources recovered from undesirable outputs
TL;DR: An approach for analyzing the reuse of undesirable intermediate outputs in a two-stage production process with a shared resource is provided and a heuristic algorithm is suggested to transform the nonlinear model into a parametric linear one.

Decomposition weights and overall efficiency in two-stage additive network DEA
TL;DR: It is shown that weights may not affect the calculation of stage efficiency scores and that variation in the overall efficiency resulting from using different weights can be associated with constant stage efficiencies.

Efficiency decomposition for general multi-stage systems in data envelopment analysis
TL;DR: This paper discusses the efficiency measurement and decomposition of general multi-stage systems, where each stage consumes exogenous inputs and intermediate products to produce exogenous outputs and intermediate Products for the succeeding stage to use.

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: 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.

Network DEA: A slacks-based measure approach

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).
