1. 1. Onboard condition monitoring of vehicle-track dynamic interaction using machine learning : Enabling the railway industry’s digital transformation

   Författare :Rohan Kulkarni; Mats Berg; Ulf Carlsson; Alireza Qazizadeh; Sebastian Stichel; Jordi Viñolas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active preventive maintenance; intelligent fault diagnosis; anomaly detection; vehicle fleet; track irregularities; vehicle hunting; wheel-rail interface.; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The railway sector’s reliability, availability, maintainability, and safety (RAMS) can significantly improve by adopting condition based maintenance (CBM). In the CBM regime, maintenance decisions are driven by condition monitoring (CM) of the asset. LÄS MER

3. 2. Machine Learning Concepts for Service Data Interoperability

   Författare :Jacob Nilsson; Fredrik Sandin; Jerker Delsing; Marcus Liwicki; Tapio Heikkilä; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; system of systems; system of cyber-physical systems; subsymbolic representations; semantic interoperability; dynamic interoperability; Cyber-Physical Systems; Cyberfysiska system;

   Sammanfattning : Industrial automation is transforming by ongoing digitalization efforts to create a flexible industrial internet of things, turning manufacturing facilities into large-scale systems of cyber-physical systems. This development requires addressing the challenging issue of making heterogeneous systems, data models, and standards interoperable, a core problem in designing sustainable service-oriented automation frameworks.
