XTRACTIS FOR predictive maintenance
Prediction of the Degradation of a Naval Propulsion Unit
Benchmark vs. Random Forests, Boosted Trees & Neural Networks
Design an AI-based decision system that accurately predicts the functional degradation of a naval propulsion unit compressor, given the hyper-complexity of the phenomenon (strongly nonlinear behavior) in order to rationally plan explainable maintenance operations.
Allow business experts and maintenance managers to understand the causal relationships between some turbine parameters and its future state of degradation.
Find the truly influential parameters for assessing the state of degradation and thus reduce measurement and maintenance costs.
Carry out maintenance actions specific to each turbine upstream in order to avoid critical damage, thanks to rapid and systematic diagnostics, while justifying each intervention.
- The top-model is a decision system composed of 27 gradual rules without chaining, aggregated into 2 disjonctive fuzzy rules.
- Each rule uses from 1 to 14 predictors among the 20 variables that XTRACTIS identified as significant (out of the 74 ones characterizing each pipe).
- Only a few rules are triggered at a time to compute the decision.
It has an excellent Real Performance (on unknown data).
It computes real-time predictions up to 70,000 decisions/second, offline or online (API).
