  1. 16. 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

  2. 17. On the identification and utilisation of relevant data for applying cost-effective maintenance

    Författare :Mirka Kans; Växjö universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maintenance information systyems; Maintenance decisions; Cost-effective maintenance; Information systems integration; Decision support systems; Industrial engineering and economy; Industriell teknik och ekonomi; Terotechnology; Systemekonomi;

    Sammanfattning : With the global and continuously changing environment of today's companies, competitive strategies of cost minimisation and differentiation, and the ability to use the available resources in a cost-effective way have become important. The major focus should be set on the areas of business where the possibilities for strategic advantages and savings are high, whereas maintenance is one area of business that recently has been considered as an activity contributing efficiently to the companies' strategic objectives of profitability and competitiveness.

  3. 18. 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.

  4. 19. Model driven process planning for machining : Theory, application and improved information standards for efficient product realization

    Författare :Mikael Hedlind; Torsten Kjellberg; Fumihiko Kimura; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; modeling; ISO 10303; CADCAM; kinematics; Beredning; modellering; ISO 10303; CADCAM; kinematik; SRA - Production; SRA - Produktion;

    Sammanfattning : Model driven process planning is a methodology that emphasizes the application of models to create, represent and use information of products, processes and resources. Industry today stores information in a fragmented manner, mainly document centered with the consequence of data duplication requiring comprehensive data management and maintenance. LÄS MER

  5. 20. Enablement of digital twins for railway overhead catenary system

    Författare :Amit Patwardhan; Ramin Karim; Rikard Granström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway catenary; Maintenance; eMaintenance; LiDAR; Point Cloud; Digital Twin; Software Architecture; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Railway has the potential to become one of the most sustainable mediums for passenger and freight transport. This is possible by continuous updates to the asset management regime supporting Prognostics and Health Management (PHM). Railway tracks and catenaries are linear assets, and their length plays a vital role in maintenance. LÄS MER
