Abstract

This research evaluates the resilience and stability of the supply chain with the theory of constraints in the offshore sector of the oil industry. The indicators were extracted by meta-combination method and screened and localized by fuzzy Delphi technique and confirmed by experts in the form of 7 dimensions and 39 indicators. The initial calculated model was checked and validated using the Partial Least Squares technique. With the SWARA technique, the dimension of "risk management" and the index of "considering the risk factor in decision-making" were given first priority. After defining the three levels of supply chain processes based on the existing process map and in accordance with the SCOR model, by implementing the WASPAS technique, the "sourcing and supply" process as the most important bottleneck process of level one, the "goods supply" process and logistics" as the most important bottleneck process of level two and the sub-process of "Purchase Planning" as the most important sub-process of bottleneck level three. Using the tools of the thinking process of the theory of limitations, the most important limitations of the bottleneck process, namely "Purchase planning", were determined and the limitation and improvement were presented. Due to the high weight of the "risk management" dimension and the "consideration of the risk factor in decision-making" index, offshore industry managers should pay special attention to the identifiction and control of risks.
