FLO: Project Facility Location Optimizer (Project FLO) is a research project created at the Institute for Mathematics of the Martin Luther University Halle-Wittenberg. The main purpose of the project is the development of a MATLAB-based software tool (aka FLO) for solving location problems.The current version 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). 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. 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.
