In particular, we address the selection of several grinding wheels to produce a milling cutter, which is a multiple-criteria decision, using multi-label classification.

Throughout the life cycle of the SLCs, they will be collected, manually checked for defects (wear, cracks, and residue on the surface), and cleaned by specialized logistic companies. Human operators in small to medium-sized companies manually evaluate the defects due to the variety and degree of possible defects and varying customer needs. This manual evaluation is not scalable and prone to errors. This work aims to fill this gap by proposing a computer vision system that can recognize the SLC type for inventory management and perform defect detection automatically. First, we develop a camera portal, consisting of standard components, that capture the relevant surfaces of the SLC. A labeled dataset of 17,530 images of 34 different SLCs with their defect status was recorded using this camera portal. We trained a classification model (ConvNeXt) using our dataset to predict the different types of SLCs achieving 100\% class prediction accuracy. For defect detection, we explore eight state-of-the-art (SOTA) anomaly detection models that achieved high rankings in the MVTec industrial anomaly detection benchmark. These models are trained using default hyperparameters and the two highest-scoring models were chosen and fine-tuned. The best-fine-tuned models based on "Area under the Receiver Operating Characteristic Curve (AUROC)" are PatchCore (0.811) and DRAEM (0.748). These results indicate that there is still potential for improvement in the automation of defect detection of SLCs.}, language = {en} } @inproceedings{MuellerEberhardtWahyudietal., author = {M{\"u}ller, Jonas and Eberhardt, Lars and Wahyudi, Vincent and Storath, Martin and Dobhan, Alexander}, title = {Towards an Approach on Location Data Analysis for Reusable Small-load Carriers}, series = {Proceedings of the Annual Hawaii International Conference on System Sciences}, booktitle = {Proceedings of the Annual Hawaii International Conference on System Sciences}, publisher = {Hawaii International Conference on System Sciences}, issn = {2572-6862}, doi = {10.24251/HICSS.2025.640}, language = {en} } @inproceedings{MuellerEberhardtWahyudietal., author = {M{\"u}ller, Jonas and Eberhardt, Lars and Wahyudi, Vincent and Storath, Martin and Dobhan, Alexander}, title = {Towards an Approach on Location Data Analysis for Reusable Small-load Carriers}, series = {Proceedings of the 58th Hawaii International Conference on System Sciences}, booktitle = {Proceedings of the 58th Hawaii International Conference on System Sciences}, pages = {5330 - 5339}, language = {en} } @inproceedings{CorsHothTschoekeetal., author = {Cors, Tobias and Hoth, Kai and Tsch{\"o}ke, Martin and Fliedner, Malte and Dobhan, Alexander and Haase, Knut and Honekamp, Wilfried and Damm, Lars and Fokuhl, Torsten and Reimers, Jonathan and Werner, Jan and Lucas, Christian and Fleischhauer Correa da Costa, Mariana and Honekamp, Ivonne and Fichtner, Liesa and Kempf, Florian and Sucky, Eric and Schneider, Larissa and Felch, Vanessa and Motschenbacher, Stefan and Straubert, Christian and Metz, Julia and Ott, Andreas and Willner, Thomas and Sievers, Anika and Kolke, Reinhard and Koch, G{\"u}nter}, title = {Mobility in a Globalised World 2019}, series = {Logistik und Supply Chain Management, Band 23}, booktitle = {Logistik und Supply Chain Management, Band 23}, editor = {Werner, Jan and Biethahn, Niels and Kolke, Andreas and Sucky, Eric and Honekamp, Wilfried}, publisher = {University of Bamberg Press}, address = {Bamberg}, isbn = {978-3-86309-731-8}, doi = {10.20378/irb-47670}, pages = {304}, abstract = {The term mobility has different meanings in the following science disciplines. In economics, mobility is the ability of an individual or a group to improve their economic status in relation to income and wealth within their lifetime or between generations. In information systems and computer science, mobility is used for the concept of mobile computing, in which a computer is transported by a person during normal use. Logistics creates by the design of logistics networks the infrastructure for the mobility of people and goods. Electric mobility is one of today's solutions from an engineering perspective to reduce the need of energy resources and environmental impact. Moreover, for urban planning, mobility is the crunch question about how to optimize the different needs for mobility and how to link different transportation systems.

Therefore, we examine usability dimensions in the Mobile ERP context in a first, preliminary study.

Therefore, after a detailed literature analysis, a usability model for the mobile application of ERP systems (Mobile ERP) is developed.

Recent studies show that the mobile use of ERP software is both, crucial for user satisfaction and still improvable for many ERP systems. Therefore, ERP-specific usability models are necessary to meet the requirements of ERP systems in comparison to e.g., apps for private use. The research objective is therefore to develop a model that enables software providers to measure and benchmark the usability of their software products. Therefore, we introduce after a literature research a usability model for the mobile application of ERP systems (mobile ERP). Our usability model is based on the widely used PACMAD model. We modify the PACMAD model for the context of ERP systems. This results in a new end-user-based model, that differs from existing models, because of its focus on end-users and the ERP context. Subsequently, the model will be tested in an initial study with 19 test persons. The results of the study indicate two main findings. Firstly, the model allows the measurement of the usability of mobile ERP systems.

Reusable container management is furthermore a solution to improve the environmental impact of the logistic industry. The sorting and stock management of small load carriers are today primarily manual work and have consequently a low level of automation. In order to increase the automation of returnable containers, it is crucial to establish a computer vision system that (i) classifies the containers and (ii) detects potential defects or stains. This paper provides an overview and a discussion of the applications that are already in use. Object detection is necessary for many actions in the container management business processes, such as inventory and stock management. Detection of defects on the small load carrier is required for scrapping the carriers to ensure a smooth process in any business process involving the carrier and to decide whether additional process steps, e.g., cleaning, are required. The literature review in this paper establishes the demand for computer vision detection and shows the project setup necessary to conduct research in this area. The comparison with other applications of defect and anomaly detection supports the applicability and shows the need for further research in this specific academic field. This leads to a project outline and the research provides the technical implementation of the detections in container management. Accordingly, the research provides a work- flow guide from data acquisition to a high-quality dataset of labeled anomalies of small load carriers.}, language = {en} } @article{EberhardtMarkertDobhan, author = {Eberhardt, Lars and Markert, Robert and Dobhan, Alexander}, title = {Towards an approach for strategic IoT architecture decision processes in SMEs}, series = {Information Systems and e-Business Management}, journal = {Information Systems and e-Business Management}, publisher = {Springer Science and Business Media LLC}, issn = {1617-9846}, doi = {10.1007/s10257-025-00712-7}, abstract = {Research in this article refers to the influencing factors during Strategic IoT architecture decisions in small and medium-sized enterprises.
