Pricing decision is one of the most important factors in the supply chain management. If demand is sensitive to the price, pricing decision becomes more important. In this case, with a slight change in the price of products or services, the customer changes his demand that impact on chain profit. In this study, a supply chain consists of two exclusive transport companies and a retail company is also taken into consideration. Each member of the system will affect price and then the profit of chain. Transport companies have a unique feature that makes them exclusive. Companies that transport hazardous chemical material, cargo liner companies in Iran and very large cargo transport company can be examples of this situation in the problem. The transport company can be a trucking company, a third-party logistics provider, or a freight forwarder. The retailer sets the retail price; this specifies the demand, which in turn, is the carrying amount for the transporters. Transporters decide the freight rate and their profit depend on both the freight rate and the carrying amount. Finally, the transporter's freight rate is an input of the retailer's cost that influences the retail price eventually. In this study, the transportation cost is divided into two categories: costs per unit of goods such as load, unload, and handling; the fixed cost per vehicle. The fixed cost includes the driver's salary, fuel charges, etc. We entered the cost per truck separately in transporters profit function that eventually led to integer linear model. We
use centralized game approach to finding the optimal price of different levels. In the centralized channel, decision makers set the retail price that maximizes the total channel profit. Coordination of three parts of supply chain and centralized decision-making can improve the system-wide profit. A new method is developed to solve the problem. After that, different sensitive analyses are illustrated for profit function graph. The results show that in the lower level of vehicle capacity, much less profit exists, and in lower fixed cost of vehicle, even less than before.After that, different sensitive analysis is illustrated for profit function graph.
