Hybrid Dynamic Network Data Envelopment Analysis [PDF]
Discrete Dynamics in Nature and Society, 2015 Conventional DEA models make no hypothesis concerning the internal operations in a static situation. To open the “black box” and work with dynamic assessment issues synchronously, we put forward a hybrid model for evaluating the relative efficiencies of ...

Classifying flexible and integer data in two-stage network data envelopment analysis [PDF]
Journal of Applied Research on Industrial Engineering, 2021 In conventional DEA models, it is supposed real-valued inputs and outputs while every measure must be determined as an input or output. However, in some cases, there are flexible measures which can only take integer values in two-stage network DEA.

Introduction a method of determining returns to scale in network data envelopment analysis [PDF]
Mathematics and Modeling in Finance, 2022 In the process of evaluating the Decision Making Units, two factors of efficiency and production size can be used. When the production size of a unit is not optimal, its Returns To Scale (RTS) determines that changing the resources in anotherdirection ...

Reconciled multiplicative relational two-stage network data envelopment analysis. [PDF]
MethodsXRelational two-stage network DEA (data envelopment analysis) is an approach for two-stage systems, where all input, output and the intermediate products have same weights regardless of which process they are related. One of the main approaches to relational model is the multiplicative relational approach where main process efficiency is the product of ...

Development of open and non-homogenous network data envelopment analysis model [PDF]
مدیریت بهره وری, 2022 In this paper, data envelopment analysis (DEA) was discussed for non-homogenous mixed network structure where the outputs of each stage can enter the next stage in the same or another layer as inputs or come out from the system as final products. In this

Identification and evaluation of congestion in two-stage network data envelopment analysis [PDF]
International Journal of Research in Industrial Engineering, 2023 Congestion is one of the important concepts in data envelopment analysis that occurs when excessive inputs reduce the maximally possible outputs. Identification and elimination of congestion have a significant impact on reducing inputs along with ...
