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} } @article{BornschleglBregullaFranke2016, author = {Bornschlegl, Martin and Bregulla, Markus and Franke, J{\"o}rg}, title = {Methods-Energy Measurement}, volume = {2016}, journal = {Journal of Cleaner Production}, subtitle = {An approach for sustainable energy planning of manufacturing technologies}, number = {135}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1879-1786}, doi = {https://doi.org/10.1016/j.jclepro.2016.06.059}, pages = {644 -- 656}, year = {2016}, language = {en} } @inproceedings{BilalKancharanaMayeretal.2022, author = {Bilal, M{\"u}henad and Kancharana, Sunil and Mayer, Christian and Bregulla, Markus and Ziębiński, Adam and Cupek, Rafal}, title = {Image-based damage detection on TiN-coated milling tools by using a multi-light scattering illumination technique}, booktitle = {Fourteenth International Conference on Machine Vision (ICMV 2021)}, editor = {Osten, Wolfgang and Nikolaev, Dmitry and Zhou, Jianhong}, publisher = {SPIE}, address = {Bellingham}, isbn = {978-1-5106-5045-9}, doi = {https://doi.org/10.1117/12.2623140}, year = {2022}, language = {en} } @inproceedings{BilalMayerKancharanaetal.2022, author = {Bilal, M{\"u}henad and Mayer, Christian and Kancharana, Sunil and Bregulla, Markus and Cupek, Rafal and Ziębiński, Adam}, title = {Damage Detection of Coated Milling Tools Using Images Captured by Cylindrical Shaped Enclosure Measurement Setup}, booktitle = {Advances in Computational Collective Intelligence. 14th International Conference, ICCCI 2022, Hammamet, Tunisia, September 28-30, 2022, Proceedings}, editor = {Bădică, Costin and Treur, Jan and Benslimane, Djamal and Hnatkowska, Bogumiła and Kr{\´o}tkiewicz, Marek}, publisher = {Springer}, address = {Cham}, isbn = {978-3-031-16209-1}, doi = {https://doi.org/10.1007/978-3-031-16210-7_21}, pages = {264 -- 272}, year = {2022}, language = {en} } @inproceedings{KovalPfallerBilaletal.2021, author = {Koval, Leonid and Pfaller, Daniel and Bilal, M{\"u}henad and Bregulla, Markus and Cupek, Rafal}, title = {An analysis of convolutional neural network models for classifying machine tools}, booktitle = {Advances in Computational Collective Intelligence}, publisher = {Springer}, address = {Cham}, isbn = {978-3-030-88112-2}, issn = {1865-0929}, doi = {https://doi.org/10.1007/978-3-030-88113-9_37}, pages = {461 -- 473}, year = {2021}, language = {en} } @inproceedings{BilalKancharanaMayeretal.2022, author = {Bilal, M{\"u}henad and Kancharana, Sunil and Mayer, Christian and Pfaller, Daniel and Koval, Leonid and Bregulla, Markus and Cupek, Rafal and Ziębiński, Adam}, title = {High Resolution Mask R-CNN-based Damage Detection on Titanium Nitride Coated Milling Tools for Condition Monitoring by using a New Illumination Technique}, volume = {vol. 5: VISAPP}, booktitle = {Proceedings of the 17th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications}, editor = {Farinella, Giovanni Maria and Radeva, Petia and Bouatouch, Kadi}, publisher = {SciTePress}, address = {Set{\´u}bal}, isbn = {978-989-758-555-5}, issn = {2184-4321}, doi = {https://doi.org/10.5220/0010781800003124}, pages = {305 -- 314}, year = {2022}, abstract = {The implementation of intelligent software in the manufacturing industry is a technology of growing importance and has highlighted the need for improvement in automatization, production, inspection, and quality assurance. An automated inspection system based on deep learning methods can help to enhance inspection and provide a consistent overview of the production line. Camera-based imaging systems are among the most widely used tools, replacing manual industrial quality control tasks. Moreover, an automatized damage detection system on milling tools can be employed in quality control during the coating process and to simplify measuring tool life. Deep Convolutional Neural Networks (DCNNs) are state-of-the-art methods used to extract visual features and classify objects. Hence, there is great interest in applying DCNN in damage detection and classification. However, training a DCNN model on Titanium-Nitride coated (TiN) milling tools is extremely challenging. Due to the coating, the optical properties such as reflection and light scattering on the milling tool surface make image capturing for computer vision tasks quite challenging. In addition to the reflection and scattering, the helical-shaped surface of the cutting tools creates shadows, preventing the neural network from efficient training and damage detection. Here, in the context of applying an automatized deep learning-based method to detect damages on coated milling tools for quality control, the light has been shed on a novel illumination technique that allows capturing high-quality images which makes efficient damage detection for condition monitoring and quality control reliable. The method is outlined along with results obtained in training a ResNet 50 and ResNet 101 model reaching an overall accuracy of 83\% from a dataset containing bounding box annotated damages. For instance and semantic segmentation, the state-of-the-art framework Mask R-CNN is employed.}, language = {en} } @inproceedings{GrossmannBregullaBanerjeeetal.2014, author = {Großmann, Daniel and Bregulla, Markus and Banerjee, Suprateek and Schulz, Dirk and Braun, Roland}, title = {OPC UA server aggregation — The foundation for an internet of portals}, booktitle = {ETFA'2014: 19th IEEE International Conference on Emerging Technologies and Factory Automation}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-4799-4846-8}, doi = {https://doi.org/10.1109/ETFA.2014.7005354}, year = {2014}, language = {en} } @article{KovalKnollmeyerMathiasetal.2024, author = {Koval, Leonid and Knollmeyer, Simon and Mathias, Selvine George and Asif, Saara and Uzair Akmal, Muhammad and Grossmann, Daniel and Bregulla, Markus}, title = {Unlocking the Potential of Information Modeling for Root Cause Analysis in a Production Environment: A Comprehensive State-of-the-Art Review Using the Kitchenham Methodology}, volume = {12}, journal = {IEEE Access}, publisher = {IEEE}, address = {New York}, issn = {2169-3536}, doi = {https://doi.org/10.1109/ACCESS.2024.3406020}, pages = {80266 -- 80282}, year = {2024}, abstract = {Data from production environments is now available in unprecedented volumes, making the problem-solving of incidents through root cause analysis straightforward. However, the root cause analysis process remains time-consuming. This study employs the Kitchenham standard systematic literature review methodology to explore how information models and deep learning can streamline this process. By conducting a comprehensive search across four major databases, we evaluate the current technological advancements and their application in root cause analysis. The aim of this study is to assesses the impact of information models for root cause analysis in a production environment. Our findings reveal that integrating knowledge graphs, association rule mining, and deep learning algorithms significantly improves the speed and depth of root cause analysis compared to traditional methods. Specifically, the use of neural networks in recent literature shows substantial advancements in analyzing complex datasets, facilitating large-scale data integration, and enabling automated learning capabilities. Comparing our findings with other recent studies highlights the advantages of using information modeling and deep learning technologies in root cause analysis. This comparison underscores the superior accuracy and efficiency of these advanced methodologies over traditional manual interpretation methods. The effective implementation of these technologies requires a robust foundation of clean, standardized data, giving rise to the concept of "Production IT." Furthermore, it is crucial for this data to be openly available to facilitate academic research, thereby enabling the development of new methods for more efficient and effective root cause analysis.}, language = {en} }
