    • 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 ...

    • Refinery optimization platform : a user’s manual : version 1.0 

      Bredström, David; Flisberg, Patrik; Rud, Linda; Rönnqvist, Mikael (Report, Research report, 2008-11)
      This is a manual for the Refinery Optimization Platform ROP which is a flexible platform for studying refinery production planning. The user can model the overall refining process in a multiperiodic setting, with linear ...

    • Refinery production planning : model and solution method 

      Bredström, David; Flisberg, Patrik; Rönnqvist, Mikael (Report, Research report, 2008-11)
      In this paper we present a general model and solution approach for refinery process planning. The model is nonlinear and has a flexible description to account for different configurations at a refinery. The solution approach ...

    • Simulation of production and sales planning in refinery operations 

      Bredström, David; Flisberg, Patrik; Rönnqvist, Mikael (Report, Research report, 2008-11)
      In this paper we discuss some computational experiments on simulating refinery operations. We compare an integrated approach with recursively solving a production planning and sales planning problem. We test two different ...
