Production processes are increasingly fragmented geographically, and the performance of production tasks is spread across countries and firms. As multinational production progresses, an intriguing phenomenon arises which is referred to as countries and firms upgrading in global value chains.In this research, we have tried to design a framework for Iranian companies in the global value chain of the automotive industry considering the time value of money, the period of payments and the costs of exchange rate fluctuations,to promote their position in the global value chain in the form of an optimization model. with Considering the actual circumstances of the selected case study (Sibamotor company), a single-objective, multi-period, nonlinear mathematical model is presented for role-playing in the global value chain. The optimal location for the construction of a possible plant, the amount of inventory in each period, the flow of CKDs and CBUs, the amount of tax and customs duty paid, the contribution of each type of payment, and etc, including the outputs of the designed model.
