Development of optimal logistics model and cooling model in front of the digestion line at the Cold Rolling Plant ArcelorMittal Poland S.A.

Storage logistics in the area of storing hot rolled coils in front of the cold mill digestion line is usually a major challenge due to the need to solve the algorithmic problem, which is referred to in literature as NP-hard. This includes solving the problem of the logistical movement of many overhead cranes simultaneously, delivering and identifying material in the form of vertebrae, mixing and moving vertebrae within the warehouse, and eventually delivering the vertebrae to the digestion line. The optimal solution to such a complex problem is additionally burdened with a numerical solution to the problem that allows for estimating the cooling time of the vertebrae, assuming different configurations of storage of vertebrae in several layers. The aim of the project is to develop a hybrid computer system that will offer a holistic approach to solving these problems by designing and implementing an integrated model of material tracking, logistics and numerical simulations. The system will be created within the first three stages of the project. In stage 1, a numerical model of coil cooling in various configurations will be developed, including measurements of vertebrate temperatures at the warehouse entrance and control measurements. Stage 2 assumes the development of a comprehensive logistics model using mixed linear integer programming methods. In stage 3, previously developed models will be integrated into the built computer system. As part of the validation of the developed system, a pilot line will be built in the warehouse of hot rolled circles in ArcelorMittal Poland in Krakow (stage 4). The installation will include an automatic control system for the transport of vertebrae, a system for automatic identification of vertebrae, autom system
