Today, supply chain management has become critical due to increasing globalization and international competition in recent years. Facility location is one of the most important issues in the global supply chain and making decisions regarding the location of facilities of different companies and organizations is one of the most fundamental decisions of organizations that can play a key role in strategic orientations of the organization and in it can lead in reducing costs and also increasing profitability in the long term.
In this dissertation, a linear, single-objective model for the global supply chain is presented which takes into account exchange rate uncertainties, demand, and harvested output. The objectives of the proposed model include maximizing network profits. The most important decisions taken in the proposed model are: locating distribution centers inside the country and abroad, assigning centers to customers, selecting the best transportation contract to send the product to distribution centers and customers, selecting the right temperature for distribution and production centers, the optimal amount of product purchase From farms and product flows between different levels of the network as well as considering the perishable nature of the product. Due to the model uncertainty nature; scenario-based, random programming is used and in the end, in order to prove the applicability of the model, Sirjan Ghiasi Pistachio Company has been studied as a case study and through computational results, the efficiency and high quality of the proposed model have been shown.
Finally, after implementing the proposed model in the case study, an internal distribution center in Sirjan and a foreign distribution center in Turkey were selected. The results of sensitivity analysis showed that the objectives of the proposed increases by increasing domestic and foreign demand, increasing exchange rates and increasing the capacity of distribution centers and the capacity of transportation vehicles.
