What is Intelligent Maintenance Systems?
Intelligent Maintenance Systems (IMS) apply machine learning and reliability models to monitor and predict failures in transportation vehicles and infrastructure using sensor data like vibration and acceleration signatures.
IMS in transportation focuses on condition-based maintenance for rolling stock, integrating digital twins for inventory optimization. Key methods include semi-Markov models for readiness evaluation (Kozłowski et al., 2023, 42 citations) and neural networks for equipment assessment (Duer, 2020, 28 citations). Over 10 recent papers analyze reliability in rail and highway systems, with citations up to 62.
Why It Matters
IMS reduces downtime and lifecycle costs in rail transport by detecting energy loss early (Fischer and Kocsis Szürke, 2023). Paś and Rosiński (2017) show reliability assessments mitigate electromagnetic interference in electronic systems, enhancing safety. Duer (2021) demonstrates neural network diagnostics improve multivalent state predictions for hybrid power systems, optimizing spare parts and service availability.
Key Research Challenges
Hidden Factor Modeling
Multimodal empirical distributions from hidden factors complicate state modeling in maintenance systems. Kozłowski et al. (2023) use semi-Markov models to address this, outperforming classical distributions. Accurate prediction remains challenging under variable conditions.
Sensor Signal Analysis
Interpreting acceleration and vibration signals under service conditions requires robust feature extraction. Kostrzewski (2018) analyzes supervised measurements but notes limitations in prototype data. Noise and variability hinder precise fault isolation.
Reliability Under Interference
Electromagnetic interference impacts electronic transport systems' operational readiness. Paś and Rosiński (2017) assess reliability but highlight assessment gaps. Integrating with fire alarm systems adds complexity (Paś et al., 2021).
