  2. 16. Integrated Bridge Maintenance : Evaluation of a pilot project and future perspectives

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

    Abstract : 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. READ MORE

  4. 17. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers

    Author : Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Vägprojektering för minskade drift- och underhållskostnader;

    Abstract : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. READ MORE

  5. 18. Leveraging Data-Driven and Alignment Techniques for Optimal Railway Track Maintenance Scheduling

  6. 19. Cost optimization of maintenance scheduling for wind turbines with aging components

    Author : Quanjiang Yu; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. 20. Property management and maintenance in the multifamily housing sector in Sweden

    Author : Henry Muyingo; Hans Lind; Stefan Olander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Property management; housing maintenance; tenant-owner; cooperative housing; maintenance planning; incentives; bostadsrätt; fastighetsförvaltning; fastighetsunderhåll; underhållsplanering; incitament; bostadsrättsförening; Fastigheter och byggande; Real Estate and Construction Management;

    Abstract : Several studies and government reports have indicated that a large number of apartments in Sweden built during the 1960s and 1970s require extensive refurbishment and that there is concern that some companies in the rental housing sector and in the tenant-owner cooperative (TOC) sector may have difficulties carrying out the needed activities. The overall purpose of the thesis is to increase the understanding of the factors that influence the decisions made within the multi­ faceted property management of multifamily housing in Sweden which would mitigate some of the shortcomings.
