Management of the overhaul of the mechanical part of the plant is the topic of this thesis. This thesis describes the mechanical part of the Dilj d.o.o. Vinkovci plant and the way in which management, planning and monitoring of overhaul is carried out. The mechanical part of the plant consists of machines for primary processing and secondary processing and presses for shaping raw tiles, tunnel kilns for drying and firing tiles, automatic machines for removing cassettes and stacking tiles on pallets, and siliconization basins. Due to the large amount of raw material that is processed and the rapid wear of parts in the company, there are daily, weekly, monthly, and annual overhauls that are necessary to maintain the working capacity of the machines. For overhauls to be successful, it is necessary to plan them in time. The process of inventory planning and spare parts ordering via the Microsoft Dynamics NAV software program is described. The Hivergen program is used to monitor the overhaul, which contains all the overhaul activities. Some of the activities performed during the overhaul of primary and secondary processing machines are shown in pictures and described.
