Journal of Resource Management and Decision Engineering 3 Serial Number 8 2024 08 24 Designing a Lean–World-Class Model in Electric Power Distribution Designing a Lean–World-Class Model in Electric Power Distribution 62 70 EN Journal Article 2024 06 24 <p>The primary objective of this study is to design a lean–world-class model in electric power distribution to evaluate the efficiency of Iran's electricity distribution chain, with the aim of improving the reliability and service quality of the electric power distribution network. Fuzzy logic-based methods enable the mathematical formulation of vague concepts and prediction. A comprehensive literature review was conducted to identify key indicators influencing lean and world-class production in electric power distribution. Face-to-face interviews were conducted, in line with the sample size required for each research method, with managers and experts at the Tehran Electricity Distribution Company. Fourteen indicators were identified, and through the fuzzy Delphi method, the extent to which Iran’s electricity distribution industry aligns with lean principles and world-class standards was assessed. In this qualitative study, the snowball sampling method was applied. The sample consisted of 26 specialists and experts. After interviewing these 26 experts from fields such as consumption management, customer services, Tehran electricity distribution dispatching, operation, and preventive maintenance (PM), 14 indicators were identified under the theme of "Designing a Lean–World-Class Model in Electric Power Distribution." Additionally, 54 concepts were extracted from the interview content and the body of existing literature and academic articles. The gender distribution among the experts interviewed comprised 12 women and 14 men, of whom 18 held master's degrees and 8 held doctorates. Through the fuzzy Delphi method and by identifying 14 key indicators and their associated concepts, this study evaluates the lean and world-class attributes of electricity distribution. It concludes that the designed lean–world-class model, with indicators such as loss reduction, value creation, enhanced reliability, and service quality in the distribution network, can significantly contribute to improving the efficiency of the electricity distribution chain in Iran.</p> https://www.journalrmde.com/index.php/jrmde/article/download/81/78
