Software Features

The current version 1.2.2 of FLO provides the following features:

  • Solving of planar single objective location problems (median- and center problems) from the literature of location theory (e.g. the Fermat-Weber problem) with regard to different distance concepts (norms and polyhedral gauges) and some types of restrictions.
  • Solving planar multiobjective location problems with respect to different solution concepts of the theory of multiobjective optimization (e.g. concept of Edgeworth-Pareto efficiency).
  • Solving special classes of non-convex single- and multiobjective location problems with attraction and repulsion points.
  • Overview of the solutions of different location problems on the map, where the solutions can be identified through colors and a classification scheme for location problems proposed in the literature by Hamacher and Nickel.
  • Detailed information about the output of all algorithms.
  • Algorithm settings can easily be changed by the user along with detailed information about the algorithm directly from within FLO.
  • Modern concepts of measuring distances between location points (for approximating real word distances) can be used through the definition of polyhedral gauges.
  • Loading of actual map images in the background of the coordinate system.
  • Location list can be exported to a spreadsheet, and a spreadsheet location list can be imported into FLO.
  • Customization of the interface and the ability to save settings between sessions.
  • Available in both German and English.
