Network DEA smallest improvement approach

Omega, 2021
Abstract 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.

Proportional trade-offs in network DEA

Computers & Industrial Engineering, 2021
Abstract This paper proposes a network Data Envelopment Analysis (DEA) framework for incorporating value-judgments in the form of production trade-offs, in order to, in detail, analyze the synchronized variations in the flows of production (input/output) factors among different divisions or sub-divisions.

Network DEA II

2014
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.

Supply Chain Evaluation by Network DEA

2023
In today’s competitive arena, performance evaluation is essential in all organizations, including the supply chain, to control, lead and plan organizations. As stated in Chap. 8, DEA is a widely used technique to evaluate the performance of DMUs, including the supply chain.

Slacks-Based Network DEA

2014
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 ...

Range Adjusted Measure Network DEA Model

AIP Conference Proceedings, 2009
In this paper, we propose a range adjusted measure network data envelopment analysis (DEA) model that can deal with the overall efficiencies as well as divisional ones in a unified framework. We show some properties of this model.

DEA for non-homogenous parallel networks

Omega, 2015
Abstract In practice, systems are often composed of a group of sub-units. Each sub-unit has a set of performance metrics that are classified as inputs and outputs in data envelopment analysis (DEA). Conventional DEA views such a system as a “black-box”, other DEA-based models are developed to investigate the inner structure, either with a serial ...

Pareto–Koopmans efficiency and network DEA

Omega, 2016
Standard 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 ...
