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

The Synthetic Efficiency Measures of the Chinese Commercial Bank System with Bad Loans and Reserve Using Two-Stage DEA Model
TL;DR: In this paper, a two-stage centralized and non-cooperative DEA approach was used to disaggregate, evaluate and test the 16 major Chinese commercial banks in 2012 with the consideration of undesirable/bad output and reserve, and the main findings of this study are as follows: i) the noncooperative model may overestimate the efficiency of ignore the relationship between the traditional stage and financial innovation stage or disagree with the real bank operation.

TL;DR: Attempts have been made to present the goals of the managers in the models of a three-stage network with optimal desirable and undesirable inputs and outputs, and a heuristic approach is suggested to convert the nonlinear models into linear ones.
