Additionally, for each target a visibility time window is given. The task is to find routes for several salespersons so that each target is reached exactly once within its visibility time window and the sum of all traveled distances of all salespersons is minimal. We present different modeling formulations for this TSP variant. The time requirements are modeled differently in each approach. Our goal is to examine what formulation is most suitable in terms of runtime to solve the multiple traveling salespersons problem with moving targets with exact methods. Computational experiments are carried out on randomly generated test instances to compare the different modeling approaches. The results for large-scale instances show, that the best way to model time requirements is to directly insert them into a formulation with discrete time steps.}, language = {en} } @misc{DeeFuegenschuhKaimakamis, author = {Dee, Robin and F{\"u}genschuh, Armin and Kaimakamis, George}, title = {The Unit Re-Balancing Problem}, series = {Mathematics}, volume = {9}, journal = {Mathematics}, number = {24}, issn = {2227-7390}, doi = {10.3390/math9243205}, language = {en} } @incollection{FuegenschuhMarahrensJohannsmannetal., author = {F{\"u}genschuh, Armin and Marahrens, S{\"o}nke and Johannsmann, Leonie M. and Matuszewski, Sandra and M{\"u}llenstedt, Daniel and Schmidt, Johannes}, title = {Using Computer-Generated Virtual Realities, Operations Research, and Board Games for Conflict Simulations}, series = {Simulation and Wargaming}, booktitle = {Simulation and Wargaming}, editor = {Turnitsa, Charles and Blais, Curtis Blais and Tolk, Andreas}, publisher = {John Wiley \& Sons, Inc.}, address = {Hoboken, NJ}, isbn = {978-1-119-60478-5}, doi = {10.1002/9781119604815}, pages = {273 -- 287}, language = {en} } @techreport{BeisegelBuhlIzaretal., author = {Beisegel, Jesse and Buhl, Johannes and Izar, Rameez and Schmidt, Johannes and Bambach, Markus and F{\"u}genschuh, Armin}, title = {Mixed-integer programming for additive manufacturing}, editor = {F{\"u}genschuh, Armin}, address = {Cottbus}, doi = {10.26127/BTUOpen-5731}, pages = {28}, language = {en} } @misc{SchmidtFuegenschuh, author = {Schmidt, Johannes and F{\"u}genschuh, Armin}, title = {Trajectory optimization for arbitrary layered geometries in wire-arc additive manufacturing}, series = {Optimization and Engineering}, volume = {25}, journal = {Optimization and Engineering}, issn = {1573-2924}, doi = {10.1007/s11081-023-09813-z}, pages = {529 -- 553}, language = {en} } @misc{GnegelFuegenschuh, author = {Gnegel, Fabian and F{\"u}genschuh, Armin}, title = {Branch-and-refine for solving time-expanded MILP formulations}, series = {Computers \& Operations Research}, volume = {Vol. 149}, journal = {Computers \& Operations Research}, issn = {1873-765X}, doi = {10.1016/j.cor.2022.106043}, pages = {1 -- 15}, language = {en} } @misc{SchmidtFuegenschuh, author = {Schmidt, Johannes and F{\"u}genschuh, Armin}, title = {A two-time-level model for mission and flight planning of an inhomogeneous fleet of unmanned aerial vehicles}, series = {Computational Optimization and Applications}, volume = {85}, journal = {Computational Optimization and Applications}, number = {1}, issn = {1573-2894}, doi = {10.1007/s10589-023-00450-x}, pages = {293 -- 335}, language = {en} } @misc{SchmidtFuegenschuh, author = {Schmidt, Johannes and F{\"u}genschuh, Armin}, title = {Temperature-Based Trajectory Planning for Surfaces in Wire- Arc Additive Manufacturing}, series = {Operations Research Proceedings 2022 : Selected Papers of the Annual International Conference of the German Operations Research Society (GOR), Karlsruhe, Germany, September 6-9, 2022}, journal = {Operations Research Proceedings 2022 : Selected Papers of the Annual International Conference of the German Operations Research Society (GOR), Karlsruhe, Germany, September 6-9, 2022}, editor = {Grothe, Oliver and Nickel, Stefan and Rebennack, Steffen and Stein, Oliver}, publisher = {Springer}, address = {Heidelberg}, isbn = {978-3-031-24906-8}, pages = {539 -- 545}, language = {en} } @incollection{BeisegelBuhlIsraretal., author = {Beisegel, Jesse and Buhl, Johannes and Israr, Rameez and Schmidt, Johannes and Bambach, Martin and F{\"u}genschuh, Armin}, title = {Mixed-Integer Programming Models for Two Metal Additive Manufacturing Methods}, series = {Mathematical Methods for Objects Reconstruction}, booktitle = {Mathematical Methods for Objects Reconstruction}, editor = {Cristiani, Emiliano and Falcone, Maurizio and Tozza, Silvia}, publisher = {Springer}, address = {Heidelberg}, isbn = {978-981-9907-75-5}, pages = {121 -- 155}, language = {en} } @techreport{SchmidtFuegenschuh, author = {Schmidt, Johannes and F{\"u}genschuh, Armin}, title = {Trajectory optimization for arbitrary layered geometries in wire-arc additive manufacturing}, address = {Cottbus ;
