Factory conditions change across machines, materials, shifts, and sites. A model must be evaluated for safety, quality, downtime, and the real operating environment.

主なポイント

• Separate alerts, recommendations, and controls.
• Evaluate across lines and conditions.
• Preserve interlocks, overrides, and data contracts.

Define whether the system detects a condition, recommends a maintenance action, or controls equipment. A visual defect alert can be reviewed; an automatic stop or setpoint change requires stronger controls and a safe failure state. Collect representative data across products, cameras, operators, and environmental conditions. Check label consistency, rare defects, sensor calibration, and the effect of a process change. Randomly splitting correlated readings can make a model look more reliable than it is on a new line. Measure false alarms, missed defects, downtime, scrap, and worker burden. A detector that catches more defects but creates an unmanageable inspection queue may not improve quality. Preserve the original signal and model version for investigation. Keep deterministic interlocks and authorized maintenance procedures around learned recommendations. Monitor drift, verify updates in a controlled setting, and provide an operator override and recovery plan.

1. Imagine a vibration sensor begins reporting values in a different unit after maintenance.
2. The model flags every machine as abnormal, creating a large alert queue.
3. Detect the input-contract change, repair the pipeline, and replay affected data rather than retraining on corrupted readings.
