As a large steel-producing country, China has become the world's largest consumption market of imported iron ore, driving the continuous growth of cargo throughput of China's ports. How can the Port-Steel enterprises in the supply chain optimize the allocation of land resources of the port and material resources of the Port-Steel enterprise to reduce the increased supply-chain costs due to the import of iron ore and achieve win–win of Port-Steel? Considering the batch distribution of iron ore demand, this paper constructs the just-in-time batch model under cooperation and noncooperation. The economic order quantity and single optimal unloading quantity under the two situations are obtained. Then the paper compares the changes of respective cost of Port-Steel and the total supply chain. The results show that under the condition of cooperation, the total supply-chain cost is lower. Through the redistribution of benefit compensation, the two sides can achieve win–win and the operation cost of the port is reduced while the inventory cost of the steel enterprise is also optimized.
