Every year, large volumes of oil products flow through the transportation network to meet the demand for these products. Optimal distribution of products in the transportation network can reduce production costs, increase energy efficiency, reduce air pollution, prevent faster depletion of these non-renewableenergy sources and use them in cases that are more urgent. Also, given that the transportation of oil products by heavy or semi-heavy vehicles increases the likelihood of road accidents and usually leads to heavier damage; Therefore, reducing the transportation of oil products is also useful in this regard. On the other hand, Iran is the center of world energy and the link between the two major oil and gas reserves _ the Caspian Sea and the Persian Gulf. For the reasonthat one of the most important characteristics of energy reserves in this area is that access to the high seas for most of these countries is possible only through intermediary countries such as Iran, and this connection is the shortest, fastest, safest and most economical route in the region. Therefore, Iran's participation in the transit of oil products can, in addition, lead to the mentioned domestic benefits, cause the economy dependence of neighboring countries on Iran,attract foreign investment, provide a suitable platform for expanding regional cooperation, achieve political and cultural goals among neighbors and regional peace and stability. In this article, during two scenarios, we examined the impact of swapping oil products through Iran specifically on Diesel Fuel product and found that swapping reduces the volume and costs of transportation. In the first scenario, we calculated the transportation costs in the case of swaps in thecountry and in the second scenario, we calculated these costs in the case of non-swaps and meeting the demand of the northern provinces by increasing the domestic production of refineries. Considering the information related to supply and demand and transportation costs of Diesel Fuel product and providing a linear planning model for this transportation issue, we calculated the costs by Tora software and specified that by performing swap transactions in Iran for Diesel Fuel product, saves 38.5% per year in transportation costs of this product.
