Abstract

The present study seeks to identify and analyze the risks in the supply chain management of gas transmission lines with a combined approach of uncertain group decision making. The case study was selected by the National Iranian Gas Company. To achieve the research goal, all the mentioned risks in different supply chains were extracted using library studies. Then, duplicate factors were eliminated and an integrated total was obtained, which included 43 risks. Then, using Delphi technique, 43 variables studied were refined and variables unrelated to the gas supply chain were excluded. There were 37 factors that were used to determine the relationships between them using the fuzzy dimtel method. Using this method, 5 levels were determined, the first level as the most effective level and the fifth level as the most effective level. There were 16 factors in the first level and 2 factors in the 5th level; Other levels also assigned different amounts of risk. Finally, using the Mick Mac technique, the degree of penetration and dependence of each risk was determined.
