    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : This Licentiate thesis addresses the topics of Joint Replenishment and Multi-Echelon Inventory Systems. Both are important parts in the concepts and current trends in Supply Chain Management and Logistics. LÄS MER

  3. 2. Polyhedral and complexity studies in integer optimization, with applications to maintenance planning and location–routing problems

    Författare :Adam Wojciechowski; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integer linear programming; complexity theory; polyhedral analysis; stochastic programming; maintenance optimization; Hamiltonian p-median problem; maintenance optimization;

    Sammanfattning : This thesis develops integer linear programming models for and studies the complexity of problems in the areas of maintenance optimization and location–routing. We study how well the polyhedra defined by the linear programming relaxation of themodels approximate the convex hull of the integer feasible solutions. LÄS MER
