DEA‐based centralized resource allocation with network flows

International Transactions in Operational Research, 2020
AbstractThis study investigates the centralized resource allocation problem among individual units using network flow theory in a data envelopment analysis (DEA) framework. Existing research on DEA‐based resource allocation is primarily concerned with the amount of allocated resources to individual units, and only a few studies have considered resource

DEA models for extended two-stage network structures

Omega, 2012
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.

DEA network computing in multi‐stage parallel processes

International Transactions in Operational Research, 2003
DEA (Data Envelopment Analysis) is a managerial method that has been widely used for performance analysis in various public and private sectors. To deal with large‐scale DEA problems, this research proposes the architecture of DEA network computing (LAN: Local Area Network) that is designed to coordinate a simultaneous use of multiple personal ...

PARALLEL NETWORK COMPUTING APPROACH FOR DEA-RAM MEASUREMENT

Asia-Pacific Journal of Operational Research, 2004
An efficiency measure, referred to as "Range-Adjusted Measure (RAM)," has been recently proposed as a new type of DEA (Data Envelopment Analysis) performance evaluator. To deal with large RAM problems, this study documents how the algorithm of RAM is designed in a parallel process. The parallel process is implemented on a Local Area Network (LAN) that

Alternative SBM Model for Network DEA

Computers & Industrial Engineering, 2015
Network DEA considers subprocesses and intermediate flows among them.Network DEA can identify more sources of inefficiency.Proposed approach provides more ambitious input and output targets and lower efficiency scores.Proposed approach adopts a system-wide perspective focusing on improving external inputs and outputs.

Scale efficiency in two-stage network DEA

Journal of the Operational Research Society, 2018
Network data envelopment analysis (DEA) considers internal structures of decision-making units. Unlike the standard DEA, network DEA imposes hurdles for measuring scale efficiency due to the fact t...

Additive Efficiency Decomposition in Network DEA

2014
In conventional data envelopment analysis (DEA), decision making units (DMUs) are generally treated as a black-box in the sense that internal structures are ignored, and the performance of a DMU is assumed to be a function of a set of chosen inputs and outputs.

Research on Multi-Index Network DEA Model

Advanced Materials Research, 2010
In view of the defect that network DEA (data envelopment analysis) can not establish the model of multi-index synchronously, we proposed multi-index network DEA evaluation method. Cost-type, fixed-type and income-type indices were managed suitably to form inputs and outputs.

Portion reduction procedure in the two-stage network DEA

2023
Summary: Data Envelopment Analysis (DEA) can be applied to a network structure systems. Considering two-stage network, this paper improves a leader-follower structure. Likewise, it is not possible to reduce the production of undesirable outputs without any cost.
