Learning outcomes
|
The maintenance, spare parts and their logistic support are the means to control the reliability and the availability of the items, its function and functions of the systems. The maintenance can affect lifetime of systems and the life cycle costs. The maintenance optimization considering costs and safety is integral part of manufacturing as well as nonproductive companies. This course contains complex information about maintenance and spare parts from their historical origins to the current trends and it shows exact mathematical tools and practical simplifications for industrial practice.
Students will gain knowledge of the principles and tools of maintenance and spare parts management with relation to economics and reliability.
