warehouse. Chan and Chan (2010) published a case study dealing with the issue of selecting a storage location for a stored item in a manually operated multi-level pallet rack warehouse. They consider the distance and time needed to remove the order as a key indicator of the efficiency of the chosen storage method. They state that when choosing a suitable warehouse management strategy and material storage method, it is necessary to consider the method of order picking, size and arrangement of the warehouse, the method of material handling, properties of stored items, customer behaviour, inventory turnover and space requirements. Vidal Vieira et al (2017) present a methodology for the design and planning of logistics activities in distribution centres (DC). The aim of this research is to design a framework for designing DC operations based on a joint study of three elements: distribution strategy, internal activities and characteristics of distribution operations. One of the outcomes of their work was the AHP decision tree for the design of logistics activities in the DC, which captures all the decisive criteria and which takes into account logistics trade-offs. The proposed AHP model of the decision problem has a very complex structure. Global criteria are receipt, shipping, picking and purchasing. In his work, Dmytrów (2020) dealt with the selection of a suitable combination of storage method and method of order picking. He used multi-criteria decision-making methods to select suitable methods. He defined the storage locations by three criteria: the distance from the delivery point, the level of satisfaction of the order and the number of products being picked near the location. He also verified the results of his calculations with computer simulations. During the simulations, he used 37 combinations of criteria weights and 18 different formulas to normalize the weights. He tested each combination on 1,000 generated orders. The result of his work was the finding that the best results were achieved when applying the diagonal arrangement of the warehouse using the ABC method, in combination with reverse tracing during picking. 2. Problem Formulation and Methodology The aim of this paper is to present the case study of application of the AHP based model for support of decision-making in process of storing finished products in the expedition warehouse of medium-fine rolling mill in selected metallurgical company. After the current state of production and logistics processes was analysed the model for dynamic management of the organization of the expedition warehouse of a metallurgical company was constructed. This model is presented below. In the next chapter of this paper the application of the proposed model on two selected warehouse events in defined warehouse conditions will be presented. 2.1 Model and Data The process map in Figure 2 shows a model of the proposed decision support system for storing bundles of finished products in the expedition warehouse of a medium section rolling mill. The following is a text description of the individual steps within the system (Malčic, 2019):
