Abstract: (127 Views)
Estimating the efficiency of interdependent parts in a company or evaluating related processes in a production system provides insights to improve production performance. In many real-world scenarios, there are situations where all DMUs fall under a centralized decision maker that oversees them. This type of situation occurs when all the units belong to an organization (public or private) that provides the necessary resources to achieve the outputs. Network data envelopment analysis (NDEA) is able to consider the operation and interdependence of the processes in the components of a system to measure performance. Recent advances in network data envelopment analysis models enable decision-making units to learn about inefficient processes in the system. In this research, by using centralized DEA models and NDEA models and according to different approaches regarding the use of intermediate products, standardization for the three-stage supply chain has been discussed. The model presented in this article has been used to evaluate the efficiency of the supply chain of 10 producers of Zamzam Company, and the obtained results have been compared with the decentralized three-stage network model.
Keywords: Network Data Envelopment Analysis, Centralized Resource Allocation, Efficiency, Supply Chain
