Two-Stage DEA: An Application to Major League Baseball
TLDR
In this article, the authors use DEA to model DMUs that produce in two stages, with output from the first stage becoming input to the second stage, and apply the model to Major League Baseball, demonstrating its advantages over a standard DEA model.Abstract:
We show how to use DEA to model DMUs that produce in two stages, with output from the first stage becoming input to the second stage. Our model allows for any orientation or scale assumption. We apply the model to Major League Baseball, demonstrating its advantages over a standard DEA model. Our model detects inefficiencies that standard DEA models miss, and it can allow for resource consumption that the standard DEA model counts towards inefficiency. Additionally, our model distinguishes inefficiency in the first stage from that in the second stage, allowing managers to target inefficient stages of the production process.read more

A two-stage DEA model with partial impacts between inputs and outputs: application in refinery industries
TL;DR: A couple of new mathematical programming models in the DEA framework are formulated with the aim of considering partial impact between inputs and outputs for calculating aggregate, overall, and subunit efficiencies along with resource usage by production lines for a two-stage production system.

Application of Network DEA Model to Vertically Integrated Electric Utilities
Miki Tsutsui,Kaoru Tone +1 more
TL;DR: In this article, the management efficiency of vertically integrated electric companies, which consist of several divisions, such as generation, transmission, distribution, and so forth, was examined, and a constrained network DEA model was proposed to obtain more practical efficiency index.

Network Data Envelopment Analysis with Fuzzy Data
TL;DR: Two approaches, the membership grade and the α-cut, are proposed for measuring the system and process efficiencies via two-level mathematical programming, and the property of the system efficiency slack being the sum of the process efficiency slacks was found to hold for the fuzzy case.

Productivity and Intermediate Products: A Frontier Approach
Rolf Färe,Shawna Grosskopf +1 more
TL;DR: In this article, the authors introduce a frontier model for productivity measurement that explicitly recognizes that some inputs are produced and consumed within the production technology, where intermediate inputs may also be final output.

TL;DR: It is found that the decomposition of production into subproduction processes reduces the dimensions of problem specification, with the effect that a larger number of variables may be usefully included in the model.
