  1. 21. Learning and Production Improvements

    Författare :Dag Swartling; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The overall purpose of the thesis is to explore the role of learning in production improvement work.The research questions are:How does learning in production relate to investments in new machinery for existing processes and new processes? How is learning in production related to using production improvement methods?The answer to the first question is that regardless if the investment is in machinery for existing processes or new processes, learning plays an important role, both in the specification phase and in the production phase.

  4. 23. Methods for availability improvements of a scaling machine system

    Författare :Andi Rahadiyan Wijaya; Jan-Gunnar Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Scaling is the process of cleaning loose material from the roof, face and wall of the mine room in underground mining. The purpose of scaling is to make the mine room safe for the next operation. Due to the nature of the task, scaling has been identified as an operation with a high number of accident occurrences.
