Businesses could greatly benefit from globally exchanging such existing knowledge across organizations to optimize their processes. Unfortunately, confidentiality concerns and the lack of appropriate designs in existing data space frameworks—both in academia and industry—greatly impair respective actions in practice. To address this research gap, we propose MapXchange, our homomorphic encryption-based approach to combine technology parameters from different organizations into technology parameter maps while accounting for the confidentiality needs of involved businesses. Central to our design is that it allows for local modifications (updates) of these maps directly at the exchange platform. Moreover, data consumers can query them, without involving data providers, to eventually improve their setups. By evaluating a real-world use case in the domain of milling, we further underline MapXchange's performance, security, and utility for businesses.}, keywords = {secure industrial collaboration; homomorphic encryption; data sharing; exchange platform; process planning; Internet of Production}, tags = {internet-of-production}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2025/2025-pennekamp-mapxchange.pdf}, publisher = {ACM}, booktitle = {Proceedings of the 40th ACM/SIGAPP Symposium on Applied Computing (SAC '25), March 31-April 4, 2025, Catania, Italy}, event_place = {Catania, Italy}, event_name = {ACM/SIGAPP Symposium on Applied Computing}, event_date = {March 31-April 4, 2025}, state = {accepted}, ISBN = {979-8-4007-0629-5/25/03}, DOI = {10.1145/3672608.3707734}, reviewed = {1}, author = {Pennekamp, Jan and Leisten, Joseph and Weiler, Paul and Dahlmanns, Markus and Fey, Marcel and Brecher, Chrstian and Geisler, Sandra and Wehrle, Klaus} } @Inproceedings { 2025_berninger_ratings, title = {Privacy-Aware Supply Chain Ratings: Interdisciplinary Research On Collaborative Supply Chain Management}, year = {2025}, month = {3}, abstract = {The establishment, expansion, and operation of reliable value-creation networks present an increasing challenge for manufacturing companies, given the growing volatility of the market environment in which they operate. For example, the development of new business areas, mass customization, or the disruption of supply chains frequently necessitates the establishment of partnerships with new suppliers, both short- and long-term. The utilization of supplier key performance indicators (KPIs) can facilitate the selection of new business partners, as they provide a quick and objective indication of their reliability. Nevertheless, access to potentially sensitive KPIs, such as a supplier's on-time delivery performance, is currently mainly limited to existing supplier relationships and not made available to other companies. This paper presents a coordinated approach for supplier rating systems, thereby enabling the privacy-aware exchange of supplier KPIs across organizations and exemplifies it using an application in the ''Internet of Production''. Specifically, we conduct interdisciplinary research by formulating the requirements from a business perspective (supply chain design, trust in data sharing, and business models) and evaluating promising solutions from a technical perspective (information security, data quality, data sovereignty, and collaboration). This approach enables the combination of state-of-the-art technology with the evolving requirements of stakeholders, thus creating new paths for exploiting inter-organizational supply chain rating.}, keywords = {supply chain management; privacy awareness; data sharing; collaboration; Internet of Production}, tags = {internet-of-production}, publisher = {publish-Ing.}, booktitle = {Proceedings of the 7h Conference on Production Systems and Logistics (CPSL '25), March 18-21, 2025, Lima, Peru}, event_place = {Lima, Peru}, event_name = {Conference on Production Systems and Logistics}, event_date = {March 18-21, 2025}, state = {accepted}, ISSN = {2701-6277}, reviewed = {1}, author = {Berninger, Stefanie and Kim, Soo-Yon and Piel, Joana and Perau, Martin and Geisler, Sandra and Piller, Frank and Wehrle, Klaus and Pennekamp, Jan} }
