Measuring the Efficiency and Performance of the Supply Chain with a Three-Stage Structure using Network Data Envelopment Analysis

The globalization of markets and the multiplicity of choices for customers have led to the formation of a supply chain. In supply chain activities, proper evaluation based on criteria can help companies move toward development. A proper system for measuring performance is an important need for effective supply chain management. Therefore, performance appraisal is critical to improving the efficiency and effectiveness of the supply chain for companies. Using a three-step approach to data envelopment analysis, this paper analyzes the data collected from 16 electricity companies, which includes three sections of production, transmission and distribution, for the years 2016 and 2017. The results show that electricity companies in Tehran, Khuzestan and Semnan provinces have an overall efficiency of one and Yazd, Gilan and Sistan and Baluchestan provinces have the lowest efficiency, which requires more attention to low-efficiency companies.
