1. Combinatorial Optimization : Three Applications
Sammanfattning : Combinatorial optimization is a diverse area of mathematics. It concerns optimization on feasible regions defined by discrete sets, graphs, hypergraphs, matroids, etc. . . LÄS MER
2. Energy and Route Optimization of Moving Devices
Sammanfattning : This thesis highlights our efforts in energy and route optimization of moving devices. We have focused on three categories of such devices; industrial robots in a multi-robot environment, generic vehicles in a vehicle routing problem (VRP) context, automated guided vehicles (AGVs) in a large-scale flexible manufacturing system (FMS).

3. Production scheduling and shipment planning at oil refineries : optimization based methods
Sammanfattning : In the oil refinery industry, companies need to have a high utilization of production, storage, and transportation resources to be competitive. This can only be achieved by proper planning The purpose of this thesis is to contribute to the development of optimization models and solution methods that support the scheduling and planning at refinery companies.

4. Modeling and optimization of least-cost corridors
Sammanfattning : Given a grid of cells, each having a value indicating its cost per unit area, a variant of the least-cost path problem is to find a corridor of a specified width connecting two termini such that its cost-weighted area is minimized. A computationally efficient method exists for finding such corridors, but as is the case with conventional raster-based least-cost paths, their incremental orientations are limited to a fixed number of (typically eight orthogonal and diagonal) directions, and therefore, regardless of the grid resolution, they tend to deviate from those conceivable on the Euclidean plane.

5. Optimal weather routing using ensemble weather forecasts
Sammanfattning : Ships small and large all battle the elements when crossing the worlds oceans. As such, ships are designed to operate in situations with high speed winds and heavy waves. There are however limits to what any ship can handle safely and it is thus important to avoid the worst weather systems as much as possible. LÄS MER
