Disadvantageous geometries provide only subpar datasets, increasing the need for a larger dataset and decreasing the accuracy of the calibration results. Moreover, an unrefined calibration method can lead to worse accuracies even with a good dataset. Here, we introduce a probabilistic method to increase the accuracy of 3D camera calibration.

All scientific approaches have in common that flexible intralogistics production networks require an autonomous and intelligent transportation systems that is not designed for a specific task, but can take on different transport roles due to their versatility. However, a comprehensive analysis of current designs and research projects in the field of AGVs and intralogistics transport robots show that there is neither the necessary interoperability of different systems nor a system architecture that addresses a flexible material flow independent of the physical design of the transportation system. AGVs mainly have a central control system, which manages the generation of transport orders and their disposition on the vehicles. In addition, the routes are specified centrally for the vehicles, even if they have free navigation. The individual transport unit is therefore only an executing machine that processes the assigned transport orders without any influence on order dispatching or route planning. Therefore, these AGV approaches do not have the flexibility and autonomy required for an intralogistics production network. The research project addresses the necessary interoperability of logistics systems and the abandonment of proprietary standalone solutions. For this purpose, methods for digitizing the workspace, route planning and path execution using a service-oriented architecture (SOA) were developed. A central component of this architecture is the approach described in the paper to enable decentralized path planning on the vehicles. Therefore, the path planning must be applicable to different target platforms without implementation effort and the vehicle software must be designed independently of the application. This approach allows intralogistics systems to be flexible and adaptable, resulting in a more sustained use of these systems.}, language = {en} } @article{DonhauserRackowHirschbrunnetal.2016, author = {Donhauser, Toni and Rackow, Tobias and Hirschbrunn, Johannes and Schuderer, Peter and Franke, J{\"o}rg}, title = {Valid Methodology for Using Discrete Event Simulation to Improve the Resource Consumption for the Manufacturing of Masonry Units}, volume = {2016}, journal = {Procedia CIRP}, number = {41}, publisher = {Elsevier}, address = {Amsterdam}, issn = {2212-8271}, doi = {https://doi.org/10.1016/j.procir.2015.12.016}, pages = {57 -- 62}, year = {2016}, abstract = {Owing to a high inflexibility of the factory layout, manufacturers of masonry units are bound to organizational adjustments seizing optimization measures.

Therefore, an IT solution for planning and controlling the operational processes is to be developed. This solution will be implemented through simulation-supported optimization to support dealing with a higher complexity and setting up a more resource-efficient manufacturing process. As a basis, a corresponding factory is mapped sufficiently accurate in every detail in a discrete event analysis (DEA) model. In this paper, a methodology, how to configure an arbitrary calcium silicate masonry unit (CS) plant in a simulation model, is presented for the first time. Relevant data is cataloged and modelling approaches for the controlling methods are pointed out. Special regard is paid to optimization measures at the crucial point of the transition from bulk material to piece goods, which has not been regarded yet in discrete event simulation modelling.

A style guide based on the Business Process Model and Notation 2.0 (BPMN) is introduced, structured around the principles of correctness, completeness, consistency, and clarity to support both communication and simulation. These principles enable reusable, verifiable process models suitable for execution in different DES tools, which serves as a step towards automated experimentation and verification. Through a first-ever evaluation of state of the art approaches against those principles, this work contributes to the ongoing definition of a semi-formal BPMN modelling layer developed in the ASIM SPL working group for formal methods in procedural models.}, language = {en} } @inproceedings{SchrageSchudererBarthetal.2025, author = {Schrage, Tobias and Schuderer, Peter and Barth, Martin and Franke, J{\"o}rg}, title = {Konzeptionierung und Integration eines KI-basierten Autoklavenmodells in ein simulationsbasiertes Entscheidungsunterst{\"u}tzungssystem in der Kalksandsteinproduktion}, booktitle = {Simulation in Produktion und Logistik 2025}, editor = {Rank, Sebastian and K{\"u}hn, Mathias and Schmidt, Thorsten}, publisher = {Technische Universit{\"a}t Dresden}, address = {Dresden}, isbn = {978-3-86780-809-5}, doi = {https://doi.org/10.25368/2025.288}, pages = {55-1 -- 55-10}, year = {2025}, abstract = {The calcium silicate brick (CSB) industry faces increasing pressure to improve the efficiency and sustainability of its production processes, especially due to the high energy consumption and CO₂ emissions associated with autoclaving. To support operational and strategic decision-making, a simulation-based decision support system (DSS) has been developed, utilizing a modular material flow simulation framework. However, the energy-intensive steam curing process in autoclaves remains insufficiently represented in existing simulation models. This paper presents a methodological approach for integrating an AI-based optimization agent for autoclave systems into the existing DSS used in CSB production. A review of current techniques for coupling AI assistance systems with discrete event simulation in production and logistics, within the building materials sector, provides the foundation. Building on this, the autoclaving process is modeled using a hybrid approach, combining thermodynamic domain knowledge with machine learning methods. This contribution highlights how the combination of simulation-based production planning and intelligent process modelling can drive digital transformation in energy-intensive industries.}, language = {de} } @inproceedings{BarthHerkelGutwaldetal.2026, author = {Barth, Martin and Herkel, Philipp and Gutwald, Benjamin and Kr{\"u}ger, Jan Hinrich and Schrage, Tobias and Reichenstein, Tobias and Franke, J{\"o}rg}, title = {Utilization of Virtual Commissioning for Simulation-Based Energy Modeling and Dimensioning of DC-Based Production Systems}, booktitle = {2025 Winter Simulation Conference (WSC)}, publisher = {IEEE}, address = {Piscataway}, isbn = {979-8-3315-8726-0}, doi = {https://doi.org/10.1109/WSC68292.2025.11339100}, pages = {700 -- 710}, year = {2026}, language = {en} } @article{BornschleglKreitleinBregullaetal.2015, author = {Bornschlegl, Martin and Kreitlein, Sven and Bregulla, Markus and Franke, J{\"o}rg}, title = {A method for forecasting the running costs of manufacturing technologies in automotive production during the early planning phase}, volume = {2015}, journal = {Procedia CIRP}, number = {26}, publisher = {Elsevier}, address = {Amsterdam}, issn = {2212-8271}, doi = {https://doi.org/10.1016/j.procir.2014.07.103}, pages = {412 -- 417}, year = {2015}, abstract = {The running costs of production sites are a decisive factor in the overheads of automotive production. Because of this, it is important for many operators to decrease those costs in a sustainable way. Therefore, they try to reduce both the energy consumption costs of production systems, as well as their maintenance costs. However, most parts of the running costs are already determined during the very early phases of the product creation process. The approach in this paper shows how the decision for a specific manufacturing technology influences the factory costs. It is necessary to determine the life-cycle costs with regard to the manufacturing technology. Therefore, deep knowledge about the process itself and the support processes is required. This paper shows how cost relevant parameters can be identified and introduces a method to determine the prospective costs for maintenance and energy consumption in advance.}, language = {en} } @inproceedings{BornschleglDrechselKreitleinetal.2013, author = {Bornschlegl, Martin and Drechsel, Michael and Kreitlein, Sven and Bregulla, Markus and Franke, J{\"o}rg}, title = {A new Approach to increasing Energy Efficiency by utilizing Cyber-Physical Energy Systems}, booktitle = {Proceedings of the Eleventh International Workshop on Intelligent Solutions in Embedded Systems}, editor = {Kucera, Markus and Waas, Thomas}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-3-00-042899-9}, url = {https://ieeexplore.ieee.org/document/6664947}, year = {2013}, language = {en} }
