  1. 26. Reliability Assessment and Probabilistic Optimization in Structural Design

    Författare :Rami Mansour; Mårten Olsson; Xioping Du; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design optimization RBDO ; First- and Second-Order Reliability Method FORM and SORM ; Response Surface Single Loop RSSL ; Probability of failure; Reliability Assessment; Probability of fatigue failure; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Research in the field of reliability based design is mainly focused on two sub-areas: The computation of the probability of failure and its integration in the reliability based design optimization (RBDO) loop. Four papers are presented in this work, representing a contribution to both sub-areas. LÄS MER

  3. 27. On reliability and maintenance modelling of ageing equipment in electric power systems

    Författare :Tommie Lindquist; Roland Eriksson; Lina Bertling; George Anders; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability; maintenance; electric power systems; circuit breaker; disconnector; thermography; Electric power engineering; Elkraftteknik;

    Sammanfattning : Maintenance optimisation is essential to achieve cost-efficiency, availability and reliability of supply in electric power systems. The process of maintenance optimisation requires information about the costs of preventive and corrective maintenance, as well as the costs of failures borne by both electricity suppliers and customers.
