Single Piles in Liquefiable Groundamming as column generation usually produces at the root node tight lower bounds (when minimizing) that are further improved when branching. Branching also helps to generate integer solutions, however branch-and-price can be quite weak at producing good integer solutions rapidly because the solution

https://doi.org/10.1007/978-3-662-49663-3basic models proposed for cutting stock and the corresponding solution approaches. Extended Dantzig-Wolfe decomposition is surveyed and applied to these models in order to show the links to Gilmore-Gomory model. Branching schemes discussion is based on the subproblem formulation corresponding to eac

Single Piles in Liquefiable Groundnsumption plants. The transporter has the responsibility for keeping the inventory level within its limits at all actual plants, and there should be no need to stop the production at any plants caused by missing transportation possibilities..Due to uncertainties in sailing time, we introduce soft in

Single Piles in Liquefiable Ground who depend on sea-transport between Norway and Central Europe. They want to achieve faster and more frequent transport by combining tonnage. This requires the possible construction of up to 15 new ships with potential investments of approximately 150 mill US dollars. The problem is a variant of the

Pawel Hawrylak,Marek Korkusińskid in algorithms. In this paper, we discuss ways of combining these techniques. We focus on solving the LP relaxation of the Dantzig-Wolfe master problem. In a first approach we apply Lagrangian relaxation directly to this extended formulation, i.e. no simplex method is used. In a second one, we use

Single Semiconductor Quantum Dotsis a sequencing problem on a single machine with time windows. The formulation is used within an exact algorithm capable of solving problems with objectives .., .., as well as an objective consistent with the Just-In-Time principle. This objective involves an irregular cost function of operation com

Quantum Dot Single-Photon Sources,ially when the main problem is to divide the jobs over the machines, column generation turns out to be very successful. Next to a number of these ‘partitioning’ problems, we shall discuss a number of other problems that have successfully been tackled by a column generation approach.
