  1. 1. Property Maintenance : Concepts and determinants

    Författare :Henry Muyingo; Hans Lind; Göran Lindahl; KTH; []
    Nyckelord :Housing maintenance; property management; real estate; housing companies;

    Sammanfattning : Introduction Strategic property management aims at balancing the question of how the needed space is to be secured, maintained, increased or disposed of in a cost effective manner under a mixture of decisions and actions. In recent years, the interest in building maintenance has increased as more and more of the housing stock built after the Second World War is in need of major renovation. LÄS MER

  3. 2. On the Transformation of Maintenance Organisations in Digitalised Manufacturing

    Författare :Jon Bokrantz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scenario planning; digitalisation; production disturbances; manufacturing; OEE; maintenance; production;

    Sammanfattning : The key to ensuring competitiveness in the future of manufacturing is digitalisation. This has been unanimously recognised by all the world’s largest economies, which is spurring global efforts that will lead to the realisation of digitalised manufacturing: the next manufacturing era that will see a seamless convergence of the virtual and physical world.

  4. 3. Integrated Bridge Maintenance : Evaluation of a pilot project and future perspectives

    Författare :Hans-Åke Mattsson; Håkan Sundquist; Jan Bröchner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge management; bridge maintenance; real service life; partnering; Building engineering; Byggnadsteknik;

    Sammanfattning : The trend in many countries is to outsource maintenance with competitive tendering. The design of the tender is then a crucial issue. A new type of tendering contract, called "Integrated Bridge Maintenance", was introduced in one experimental area in Sweden. LÄS MER

  5. 4. Cost optimization of maintenance scheduling for wind turbines with aging components

    Författare :Quanjiang Yu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer linear optimization; Age-based preventive maintenance scheduling; Renewal-reward theorem; Weibull distribution; Combinatorial optimization; Wind turbine maintenance; Virtual replacement; Condition monitoring data; Cox proportional hazards method; Linear programming;

    Sammanfattning : A major part of the wind turbine operation cost is resulted from the maintenance of its components. This thesis deals with the theory, algorithms, and applications concerning minimization of the maintenance cost of wind power turbines, using mathematical modelling to find the optimal schedules of preventive maintenance activities for multi-component systems.

  7. 5. Cost-effective maintenance of railway track geometry : a shift from safety limits to maintenance limits

    Författare :Iman Arasteh Khouy; Peter Veit; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : Railway infrastructure is a complex system which comprises different subsystems. Long life span is one of the important aspects of this prime mode of transport. However, the useful life of its assets is highly dependent on the maintenance and renewal strategy used during the assets’ life cycle. LÄS MER
