Combining models in a multi-scale simulation can exploit their advantages. The macroscopic flow model excels at modeling the behavior of large quantities of piece goods, however, it cannot provide information about individual piece goods. This led to the approach of the combination with a microscopic physics-based model in a multi-scale material flow simulation. To switch between models, the coordinates of the positions (microscopic) have to be translated in one direction into the material description of the macroscopic flow model (the density distribution). In the other direction, the density distribution has to be translated into the coordinates of the positions, leading to a computationally intensive optimization problem. This paper develops various methods for finding a start solution and compares them to a method of the state of the art. The evaluation is based on their accuracy with reference to various parameters of the data set. The results show the best accuracies for the method which traverses the density distribution and calculates the sum of the densities until it matches a single piece good. Depending on the accuracy required, it may be possible to use the start solution directly without further optimization.", "doi" : "10.1109/ICECCME62383.2024.10797016", "bibtexKey": "10797016" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2ed5ac9680f01a806010b1c8133411ac2/isw-bibliothek", "tags" : [ "myown","simulation","learning","isw" ], "intraHash" : "ed5ac9680f01a806010b1c8133411ac2", "interHash" : "590d7afb375cb3a264d43efe9daf1405", "label" : "Simulationsmodelle der Virtuellen Inbetriebnahme als Lernumgebung für Reinforcement Learning", "user" : "isw-bibliothek", "description" : "", "date" : "2024-02-22 17:00:03", "changeDate" : "2024-02-22 17:00:03", "count" : 2, "pub-type": "inbook", "booktitle": "Echtzeitsimulation in der Produktionsautomatisierung: Beiträge zu Virtueller Inbetriebnahme, Digitalem Engineering und Digitalen Zwillingen","publisher":"Springer Berlin Heidelberg","address":"Berlin, Heidelberg", "year": "2024", "url": "https://doi.org/10.1007/978-3-662-66217-5_13", "author": [ "Florian Jaensch","Alexander Verl" ], "authors": [ {"first" : "Florian", "last" : "Jaensch"}, {"first" : "Alexander", "last" : "Verl"} ], "editor": [ "Alexander Verl","Sascha Röck","Christian Scheifele" ], "editors": [ {"first" : "Alexander", "last" : "Verl"}, {"first" : "Sascha", "last" : "Röck"}, {"first" : "Christian", "last" : "Scheifele"} ], "pages": "213--227","abstract": "Die steigenden Anforderungen der Produktionstechnik nach flexiblen und trotzdem wirtschaftlich effizienten Anlagen stellt die Automatisierungstechnik vor große Herausforderungen.

This paper presents a novel concept that enables structured storage of CPPS production data as part of a digital twin that serves as a virtual replica of the physical production environment. In particular, this approach is based on the Asset Administration Shell (AAS), which provides a comprehensive framework for the management of production data and allows for a seamless integration with simulation models.

The automation of production systems is one of those fields. Normally, programming a control system defines the automation strategy. Previous contributions by the authors have shown that a so-called agent can learn automation strategies for production systems using a Reinforcement Learning setup. However, the development of the reward function for the agent can be challenging and needs Reinforcement Learning domain knowledge. This paper introduces a novel approach in combining Test-Driven Development with Reinforcement Learning in order to solve the problem of a suitable reward function. In the presented approach predefined test cases are used to derive rewards for the agent. The use of an automated test framework allows for continuous learning sequences until all test cases are passed. An application example of a robot cell is used to demonstrate the novel approach and verify its suitability and usability.

In these cases the hybrid commissioning (HCOM) method, a hardware-in-the-loop (HIL) simulation setup including both real and simulated components, is desirable.

However, the available data exchange rates for these communication platforms are limited to a few hundred Hertz. As the data is not available in high frequency resolution, such a network communication is not suitable for monitoring and optimizing highly dynamic machining processes. This paper describes an efficient system architecture, which enables the acquisition of internal machine data as well as the high frequency sampling of external sensors. Based on this data, an Operational Modal Analysis (OMA) approach can be used to determine the tool tip dynamics during the machining process. Identification of tool tip frequency response requires the reconstruction of the excitation of the machine tool structure, i.e. the occurring machining forces. For this purpose, an approach relying on monitoring the commanded motor currents is applied.", "issn" : "2212-8271", "doi" : "https://doi.org/10.1016/j.procir.2021.01.097", "bibtexKey": "SCHMUCKER2021342" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/274eb90af7e47b927d3415f4faae2bf31/isw-bibliothek", "tags" : [ "Messen/Steuern/Regelnsend:unibiblio","Simulation","Industrieroboter" ], "intraHash" : "74eb90af7e47b927d3415f4faae2bf31", "interHash" : "5819722740e0c959092aaca5d1526e4f", "label" : "Dynamisches Verhalten von Industrierobotern - Über das Potenzial von Secondary Encodern zur Vermessung", "user" : "isw-bibliothek", "description" : "", "date" : "2021-01-11 13:53:23", "changeDate" : "2021-01-11 12:53:23", "count" : 1, "pub-type": "article", "journal": "wt Werkstatttechnik online", "year": "2020", "url": "", "author": [ "Michael Neubauer","Patrick Mesmer","Armin Lechler","Alexander Verl" ], "authors": [ {"first" : "Michael", "last" : "Neubauer"}, {"first" : "Patrick", "last" : "Mesmer"}, {"first" : "Armin", "last" : "Lechler"}, {"first" : "Alexander", "last" : "Verl"} ], "volume": "110","number": "3","pages": "130-134", "bibtexKey": "neubauer2020dynamisches" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/20caf0d4c1fa0a22e9cb09d879747d915/isw-bibliothek", "tags" : [ "myown","SimTech","simulation","grk2198","control","EXC2075" ], "intraHash" : "0caf0d4c1fa0a22e9cb09d879747d915", "interHash" : "7ea6f821bac9b5e24f166f5f0e7cb3b9", "label" : "Nonlinear Trajectory Control for Deformable Linear Objects based on Physics Simulation", "user" : "isw-bibliothek", "description" : "", "date" : "2020-11-20 11:08:22", "changeDate" : "2021-12-09 15:00:06", "count" : 2, "pub-type": "inproceedings", "booktitle": "IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society", "year": "2020", "url": "https://ieeexplore.ieee.org/document/9254923/", "author": [ "Christoph Hinze","Manuel Zürn","Markus Wnuk","Armin Lechler","Alexander Verl" ], "authors": [ {"first" : "Christoph", "last" : "Hinze"}, {"first" : "Manuel", "last" : "Zürn"}, {"first" : "Markus", "last" : "Wnuk"}, {"first" : "Armin", "last" : "Lechler"}, {"first" : "Alexander", "last" : "Verl"} ], "pages": "310-316","abstract": "The handling of deformable linear objects (DLOs), such as cables or hoses, with industrial robots is hardly industrially automated due to the underactuated material behavior. Increasing computing power and decreasing cost of processors over the last decades are now allowing the online computation of more complex handling processes. Within this paper, DLOs are approximated as a multibody chain with a finite number of degrees of freedom. Based on that model, a nonlinear, partially IO-linearizing controller is derived to control an underactuated end point on a trajectory when grasped by a robot arm at the other end. The controller is verified in simulation for high dynamics and shown to significantly reduce the tracking error. A practical evaluation finally shows the qualitative suitability of the multibody approximation and is used to validate the functionality of the controller in an open-loop experiment.", "issn" : "2577-1647", "doi" : "10.1109/IECON43393.2020.9254923", "bibtexKey": "9254923" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2c3f6c769d0824fd62f567ad016d2cd61/isw-bibliothek", "tags" : [ "simulation","materialfluss","isw" ], "intraHash" : "c3f6c769d0824fd62f567ad016d2cd61", "interHash" : "2b6504b497e898e9d79e1fdd1aa04919", "label" : "Simulative Optimierung der Steuerungsparameter eines Materialflusslayouts mit Bandförderern", "user" : "isw-bibliothek", "description" : "", "date" : "2020-10-27 15:44:33", "changeDate" : "2020-10-27 14:44:33", "count" : 1, "pub-type": "article", "journal": "Forschung im Ingenieurwesen", "year": "2020", "url": "https://doi.org/10.1007/s10010-020-00420-3", "author": [ "Annika Kienzlen","Jennifer Weißen","Alexander Verl","Simone Göttlich" ], "authors": [ {"first" : "Annika", "last" : "Kienzlen"}, {"first" : "Jennifer", "last" : "Weißen"}, {"first" : "Alexander", "last" : "Verl"}, {"first" : "Simone", "last" : "Göttlich"} ], "abstract": "Moderne Fertigungssysteme sind komplexe, umfangreiche Systeme.
