Tiivistelmä
The majority of failures and maintenance operations of passenger information systems are caused by the so called consumable components ‒ electrical components or modules which have significantly lower expected lifetimes compared to surrounding electronics in a device. This thesis identifies the consumable components and investigates their useful lifetimes within Teleste Corporation’s on-board systems portfolio. A better understanding of the required maintenance operations within a passenger information systems’ lifetime can be achieved through these approximations. Maintenance and maintainability are becoming more important within the public transport market. Analysis and improvement of maintenance processes are critical in providing efficient support throughout passenger information systems’ long lifetime.
