Risk of spare part of machines and equipment inventory control in decommissioning
Jirka, Lukáš ; Řezníčková, Hana (referee) ; Kotek, Luboš (advisor)
This thesis deals with design of a suitable approach for managing the supply of spare parts for machines approaching decommissioning. The appropriate balance between outstanding risks related to equipment downtime and costs of holding spare parts is predicted by proposed systematic algorithm. Determination of key parameters affecting the whole process of spare parts inventory management and their subsequent use as a basis for Event Tree Analysis lead to finding an optimum set-up, which mitigates the overall impact of the planned reduction in spare parts storage levels. The new approach has a number of advantages including versatility of application for many types of machines, as well as a different outlook on a solution for the current issue in spare parts management.

Renovation of expensive spare parts using of special engineering technologies.
DOLEŽEL, Zdeněk
This masters thesis deals with renovations expensive spare parts for the use of special engineering technologies. The aim was to compare and evaluate the technical and economical technological processes used components renovations. In the theoretical part are written information obtained from literature sources dealing with the basic concepts, definitions and describes the most commonly used technology renovation. In their study were selected components for renovation, where it is necessary to use special methods of engineering technologies. The first part was chosen balancer shaft used for four-cylinder diesel engine Volkswagen. For component was suggested special technological process of repair, so as to achieve low prices, but also guarantee a high quality repair and threaten further damage. Price repairs were compared against the cost of a new spare part. Another component was selected renovation speed bump for truck Scania. For component was suggested technological process of repair. Prices renovations by various techniques were compared.
