Four views over wheel measurement data — how fast wheels wear, how much life is left, and how much reframing work is coming.

Intervalltrend — rolling monthly kilometres between lathe operations, per wheel type

Lifetime averages plus a rolling monthly series, for both kilometres and days between events. The two intervals count differently on purpose:
  • A lathe interval restarts at any of delivery, lathe or reframing.
  • A reframing interval restarts only at delivery or reframing, so it accumulates the full wear cycle since the last full restoration.

RUL-karta — remaining life per wheel position for the selected vehicle

A per-vehicle, per-position snapshot of wear margin:
The reading comes from whichever component is currently mounted, so wear follows the component as it moves between positions rather than staying with the position.

Omstomningsprognos — median wheels due per month, with the 10th-to-90th-percentile band

Answers a workshop capacity question: how many wheels across the fleet will need reframing in each calendar month over the next twelve, with uncertainty bands. It is deliberately a fleet count, not a per-wheel prediction of dates.
A Monte Carlo simulation over roughly two thousand draws, reporting the median, mean and a 10th-to-90th-percentile band per month.Wear rate is drawn from the component type’s population rather than the individual wheel’s own history, on the reasoning that wheels of a type are interchangeable and get swapped across trains and positions during their life.Remaining material comes from the last known diameter — the most recent delivery, lathe or reframing event — minus wear already accrued since.Kilometres become calendar time through a usage rate pooled across the vehicle type, so a vehicle with sparse readings inherits its type’s duty cycle.
Wear is not the only thing that brings a wheel in. Where a measurement threshold names a reframing task in a maintenance plan, the scheduled interval acts as a cap: whichever comes first — wear reaching the limit, or the preventive schedule falling due — is what the forecast counts.The page reports how many wheels are in scope and how many carry such a cap.
The forecast is cached and recomputed monthly, and can be run as of a past date for a genuine point-in-time view.
Measurement types, their thresholds and their progression rules are configured on Measurements. The underlying data arrives via the measurements import.
