  5. 4. Visual replenishment methods in the manufacturing industry and suggestion for a decision tool

    Författare :Stefan Eriksson; Lars Bengtsson; Mauro Onori; Peter Gröndahl; Stig-Arne Mattsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materials supply; replenishment methods; visual; selecting methods; decision tool;

    Sammanfattning : In almost all supply chains, materials need to be stored or buffered, implying that manufacturing companies need effective replenishment methods. However, this is challenging, since companies must balance inventory costs and customer service in complex and different situations. Therefore, it is important to choose replenishment methods carefully. LÄS MER

  7. 5. Real konstruktivism : Ett försök till syntes av två dominerande perspektiv på undervisning och lärande

    Författare :Stefan Sellbjer; Jan Bengtsson; Växjö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pedagogic theory of knowledge; intuitive theories; teachers thinking; folk pedagogy; folk psychology; teaching; learning; scientific knowledge; tools; paradigm; traditional perspective; social constructionism perspective; interpretative realistic perspective; Education; Pedagogik; Pedagogik; Pedagogics;

    Sammanfattning : The starting-point of the thesis was that teachers to a large extent teach on the basis of intuitive theories. This creates a tendency that a number of frequent conceptions, pedagogical and didactic theories, experiences of one's own school days etc. become parts of a more fragmentary structure of ideas, rather than a coherent theory of teaching.
