• Coordination of refinery production and sales planning 

      Bredström, David; Rönnqvist, Mikael (Report, Research report, 2008-11)
      Coordination of activities in the supply chain is important in order improve the overall performance. The best approach is to use integrated planning of such activities. However, in many cases it is not possible to use ...
    • A new method for robustness in rolling horizon planning 

      Bredström, David; Rönnqvist, Mikael (Report, Research report, 2008-11)
      In this paper we describe a new method to solve Linear Programming (LP) problems with uncertain parameters. We apply this to planning problems where a rolling planning horizon is used. The method is based on a decomposition ...
    • Patterns in the relative price for different sizes of fish : biological price generating processes in fish farming 

      Asche, Frank; Guttormsen, Atle G. (Working paper, Working paper; Working paper, 2000-09)
      Fish farming is a biological production process dependent upon biological and environmental conditions. These constraints imply that fish farmers are likely to have a quite similar distribution of different sizes of fish ...
