  2. 11. Towards Model-Based Condition Monitoring of Railway Switches and Crossings

    Author : Marko Milosevic; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sleeper void; Switches crossings; condition indicators; embedded sleeper accelerometer; multi-body simulations; dynamic vehicle–track interaction; MBS; S C; wheel–rail contact forces; condition monitoring; crossing rail geometry; displacement reconstruction.; model calibration;

    Abstract : Railway switches and crossings (S&C, turnouts) connect different track sections and create a railway network by allowing for trains to change between tracks. This functionality comes at a cost as the load-inducing rail discontinuities in the switch and crossing panels cause much higher degradation rates for S&C compared to regular plain line track.

  4. 12. Environmental management systems : policy implementation and environmental effects

    Author : Thomas Zobel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Abstract : Corporate environmental management is becoming less driven by regulatory compliance and more driven by corporate strategy. In order to gain competitive advantage, systematically assure regulatory compliance and develop more efficient operations an increasing number of organisation adopt the environmental management system (EMS) tool.

  5. 13. On efficient use of censored data and covariate factors in survival analysis and maintenance scheduling

    Author : Ulf Westberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

    Abstract : This thesis deals with survival analysis and maintenance scheduling, two important issues to achieve efficient use of different production systems. In survival analysis of failure time data, the survival function and the cumulative hazard function are important reliability characteristics. READ MORE

  6. 14. Strategic Maintenance Development focusing on use of Condition Based Maintenance in Manufacturing Industry

    Author : Ali Rastegari; Mats Jackson; Aditya Parida; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Innovation and Design; innovation och design;

    Abstract : The growth of global competition caused remarkable changes in the way manufacturing companies operate. These changes have affected maintenance and made its role even more crucial in business success. In order to stay competitive, manufacturing companies need to continuously increase the effectiveness and efficiency of their production processes. READ MORE
