OEE Calculator and Loss Analyzer

Turn time, count, and loss data into a practical OEE view with Availability, Performance, Quality, a Six Big Losses Pareto, projected-gain simulation, and saved-run history.

Analyzer

Enter the current production run

Core formula: OEE = Availability x Performance x Quality

Use one line per loss category as `Category, value`. The standard Six Big Losses labels work best. Enter minutes for downtime and speed losses. Enter rejected units for the two reject categories; the app converts them to ideal-time minutes for Pareto ranking.

Instructions

How to use this app

  1. Enter planned production time, ideal cycle time, total count, and good count.
  2. List the Six Big Losses on separate lines. Use minutes for downtime and speed losses, and rejected units for the two quality-loss rows.
  3. Click `Analyze OEE` to calculate OEE plus the Availability, Performance, and Quality components.
  4. Use the simulator to reduce one loss category and see the projected OEE gain immediately.
  5. Click `Save Run` to add the current result to a local trend history on this device and browser.

The simulator is directional. It assumes the chosen loss reduction converts directly into productive time or recovered quality output without changing the other factors.

If your reduced-speed losses are not tracked in minutes today, estimate them as the gap between ideal output and actual output converted into time at ideal cycle.
