Thread Gauge RUL

Discrete-time survival prediction with GO / NO-GO tolerance check.

Checking Thread gauges
Event MAE--days
Interval AUC--hazard

Gauge input

Picks a multi-cycle held-out gauge at random and auto-populates every pre-failure cycle.

Measurement cycles

Prediction

Awaiting input
Predicted RUL--days
Failure date--predicted
180-day risk--survival
365-day risk--survival
Rule status--GO / NO-GO
Any GO or NO-GO measurement crossing the lower/upper limits forces RUL to zero.

How the model arrived at this prediction

Run a prediction to see a plain-English breakdown.

The margin-trajectory chart below shows this gauge's worst-margin over its calibration history — it's the visual companion to the drift status above. A flat or rising line means the gauge is stable; a falling line means it's degrading toward the limit.

Ask in plain English

Ask anything about this prediction — e.g. "why is this gauge risky?", "what should I tell my boss?", "how does this compare?"

Prediction graphs

Run a prediction to populate the charts.

Survival curve

Probability the gauge is still alive after N days from now.

Margin drift per cycle

Per-cycle rate of change of the worst-min margin (mm / day). Negative = degrading toward the limit. Dashed segments highlight cycles where the gauge actually worsened.

Failure risk by year

Probability the gauge will have failed by the end of each future year. Bars are coloured by severity: green low risk, amber moderate, red elevated.

Margin trajectory

This gauge's worst-min margin over its calibration history. Negative = breach. The vertical dashed line marks the boundary between data the model used and ground truth shown for comparison only — anything to the right of it was hidden from the model.
