Storage and stocking activities are very strategic for enterprises in terms of time, space and cost. The critical issues such as operation of the production line, flow without hesitation, timely and appropriate conditions of supply, minimization of waste and other losses as well as control of production costs make warehouse management more attractive day by day. One of the most important decisions about storage is how to arrange the materials to be placed on the shelves. Shelves, which are among the main sources of the enterprise, where stock items are stored and which are preferred as the means of displaying products, are also a strategic tool for effective warehouse management. If shelf management and material assignments are made effectively, continuity and efficiency in production will be ensured, and optimization of used and unused areas on shelves will be possible. In this regard, using stock areas efficiently is seen as the primary objective. In this study, it is investigated how the materials can be placed on the shelves in the stock area by assigning the most space to use. It is studied in a company that produces food packaging. It is aimed to increase the capacity of the company's semi-finished warehouse and to optimize shelf placement according to the dimensions of the products produced. For this purpose, the data obtained from the company through one-to-one analysis, firstly using the Knapsack model, one of the operational research techniques, for the most efficient shelf type determination, then the shelf space optimization was performed by using integer programming technique to find out how many of these determined shelf types should be. The aim is to ensure the most efficient use of the space by converting the 2-storey shelf system into a 3-storey shelf system considering the radii of the coils that the enterprise considers as stock material. At the same time, the current and proposed system of the stiuation has been simulated with the ProModel simulation program.
