Network DEA smallest improvement approach
Omega, 2021Abstract In this paper the smallest improvement DEA approach to general networks of processes is proposed. The corresponding projection direction is endogenously computed by the model so that the relative distance to the frontier is minimal. Both the cooperative and the non-cooperative scenarios for the intermediate products are considered.

The original DEA model by Charnes et al. (Eur. J. Oper. Res. 2:429–444, 1978) is set to analyze production as a black box, i.e., there is no information about the processes inside. Network DEA was proposed for analysis of the contents of the black box.

DEA‐based centralized resource allocation with network flows
International Transactions in Operational Research, 2020AbstractThis 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

Traditional DEA models deal with measurements of relative efficiency of DMUs regarding multiple-inputs versus multiple-outputs. One of the drawbacks of these models is the neglect of intermediate products or linking activities. After pointing out needs for inclusion of them to DEA models, we propose a slacks-based network DEA model that can deal with ...

Scale efficiency in two-stage network DEA
Journal of the Operational Research Society, 2018Network 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...

PARALLEL NETWORK COMPUTING APPROACH FOR DEA-RAM MEASUREMENT
Asia-Pacific Journal of Operational Research, 2004An 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

Sensitivity analysis of network DEA: NSBM versus NRAM
Applied Mathematics and Computation, 2012Users of data envelopment analysis (DEA) often presume efficiency estimates to be robust. While traditional DEA has been exposed to various sensitivity studies, network DEA has so far escaped similar scrutiny. Thus, there is a need to investigate the sensitivity of efficiency estimates, further compounded by the recent attention network DEA has been ...

Pareto–Koopmans efficiency and network DEA
Omega, 2016Standard or black-box data envelopment analysis (DEA) evaluates the efficiency of the transformation of a DMU׳s exogenous inputs into its final outputs by ignoring what is going on in its divisions (sub-DMUs). To cope with this problem, network DEA (NDEA), which can provide adequate detail to management, has been developed and applied empirically ...

Portion reduction procedure in the two-stage network DEA
2023Summary: 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.
