    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Mattias Holmgren; Luleå tekniska universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : The satisfaction of stakeholders depends upon the fulfilment of their requirements. Two important stakeholder requirements related to technical systems are dependability and safety. However, system operation will gradually impair its performance leading to potentially hazardous states of the system. LÄS MER
