When designing a logistics system, it is important to know the goals you want to accomplish and achieve. A logistics system can be understood as a system whose primary goal is to meet the needs of the end user in order to achieve commercial profit. In order for the system to function properly, it is necessary that all parts involved in the flow of goods, from production, storage, to transport and distribution, are informationally connected and physically compatible. Great importance should be attached to the planning and organization of the system because even the slightest mistake can have significant consequences that can be seen in increased costs, reduced profits, ie. loss of interest or confidence of the end consumer. Capacity planning is an important part of the entire logistics system, be it planning in the amount of production, the size of the warehouse, the number of workers or the amount of transport required. The paper is divided into two parts, the first part is theoretical, which deals with defining the basic concepts of logistics processes, and the second part deals with a practical example of logistics capacity. Explaining the roles of the bearers of logistics processes provides a broader picture of the need to synchronize certain parts that directly and /or indirectly affect each other. Then, the methods of planning logistics processes are explained, and special attention is paid to timely response when making plans and selecting appropriate procedures for making the most optimal system. The capacity planning of logistics systems emphasizes the importance of storage space, as well as the importance of transport services, in order to avoid the bottleneck problem caused by poor process planning and non-compliance of this part of the system with other parts. The main part of the paper is focused on the planning and control of capacity and the process of transshipment, storage and transportation of aluminum logs in the Port of Šibenik.
