  6. 9. Multi-Echelon Inventory Control with General Backorder Cost Structures and Emissions

    Author : Lina Johansson; Produktionsekonomi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures. Backorder costs are traditionally assumed to be linear, whereas we consider structures that are more general functions of the customers’ time in backorder. READ MORE

  7. 10. Enhancing aftermarket demand planning with product-in-use data
