    Author : Thomas Åhrén; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The Swedish railway authorities have a long tradition of using performance indicators to follow up their performance. Already in 1915 when they decided to electrify the iron ore line between Kiruna and Riksgränsen, they introduced some indicators to measure and follow up expected benefits of upgrading the transportation system, e.g. READ MORE

  7. 25. An assessment of operational consequences of failures to support aircraft scheduled maintenance program development

    Author : Alireza Ahmadi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : A majority of the direct and indirect maintenance costs in the life cycle of aircraft stems from the consequences of decisions taken during the initial maintenance program development. In particular, the preventive and corrective maintenance requirements, which greatly influence both the system availability and life cycle cost, need to be defined in order to perform only those preventive actions that are absolutely necessary and costeffective.
