The most important motive for conducting research on this topic is the feeling of need in the field of foreign trade of our country despite restrictions such as international sanctions and economic pressures. The need to deal with this issue is the conditions of the cruel Western sanctions against Iran and the thirty percent decrease in our country's income, which is detailed and documented in the first chapter. In this situation, Bartering is an intermediate solution to reduce the effects of sanctions In the second chapter, we reviewed the literature of this field in detail and explained various concepts and definitions and mathematical models. The research method presented in the third chapter is the combination of a mixed integer linear programming modeling research method along with a real case study. The method adopted to explain the issue is to design a mathematical model with the aim of eva‎luating the value of the bartering supply chain by defining a new bartering platform called the barter pool. By solving the model with random and real data and calculating the value of the bartering chain, we showed that the model has the correct structure and pattern. This mathematical model was solved in the fourth chapter through random data using Gams software, and through real data in this chapter, a case of bartering trade between Iran and Venezuela was investigated and the value of the supply chain was studied again with Gams software in an approximate form. will be measured. At the end of the fourth chapter, the model is examined from another angle by analyzing the sensitivity of oil price fluctuations and timber price fluctuations in different seasons. In the fifth chapter, the summary and management recommendations as well as the innovations of the thesis are presented and suggestions for future research are presented.
