Abstract :

In this research, a framework for optimizing the oil condensate supply chain is modeled using mathematical programming to design and make strategic and tactical decisions. Based on this framework, investment and operating costs and greenhouse gas emissions for oil and gas transmission lines can be minimized to meet pressure and transmission network needs. We can also minimize the production of pollutants in the related parts of the chain. By applying a real case study, all possible decisions are taken into account to consider the environmental aspects of the supply chain. Therefore, the structure and decisions of the supply chain are generally based on two objective functions, including the reduction of transportation and maintenance costs and pollution in treatment plants and distribution centers. The proposed model is reliable with good accuracy compared to simulation modeling and NSGA-II meta-heuristic algorithm and can estimate the objectives well. Using the proposed model reduces costs by 31% and greenhouse gas emissions by 51%. There will also be an 8% increase in the capacity of fields and refineries and a 65% increase in exports. Using the results obtained from solving the model, it is possible to determine the share of each oil product in the total price and each part of the chain in the production of greenhouse gases.
