OEE

How is OEE calculated?

Overview

Measuring the Availability, Performance and Quality (APQ's) of a Line, Asset or Equipment is a key pillar of Industry 4.0. TilliT achieves this through simple measurements of your equipment statuses, production counts and downtime classification. All of these can be ingested into TilliT via manual Activities, our TilliT Edge solution or Integration via API/MQTT. Completing this setup in TilliT unlocks the full reporting potential of your operations to drive and measure continuous improvement programs.

Where to find OEE in TilliT?

When you select an asset, you can find a breakdown of your APQ's on the asset card by clicking the Metrics button and next to the date selection. This will only show you the past 3 hours of production. For a full history, you need to utilise the Production Report or Dashboarding

Two Steps to Availability

Configure shifts for your assets. This way TilliT knows when you should and shouldn't be in production. Any downtime outside of production hours will not penalize your availability. This defines what 100% availbility will be. See Shift Patterns.

Ingest machine statuses into TilliT. For best results, you need to read local datasources with a TilliT Edge device or Integrate via API/MQTT. See the Equipment Status Templates for ingesting via edge or Publish Order Progress for using MQTT. When you do experience a stoppage event, attach a reason code to understand what caused the downtime via a machine tag or activity submission. Classify your reason codes as planned or unplanned to only measure the downtime you want to effect Availability. See Option List and Edge Downtime.Downtime during your order changeover will automatically be measured as planned until scheduled changeover duration is exceeded. At this point, unplanned downtime will start to negatively effect your availability. See Order Changeover

Two Steps to Performance

Define your asset or equipment to have a default run rate. This will be your target to achieve 100% performance. Alternatively, each order can have a different default run rate and order performance will be measured using this instead of the asset or equipment default run rate.

Ingest production counts into TilliT. For best results, you need to read local datasources with a TilliT Edge device or Integrate via API/MQTT. See the Equipment Status Templates for ingesting via edge or Publish Order Progress for using MQTT.If the equipment does not contain any knowledge aboout it's production count, then use our wireless gateway and sensors offerings to start measuring performance in a matter of hours. Learn more at Setting up your Site for TilliT Edge. As a last resort, you can ingest production counts for an Activity created inside TilliT for your operators to fill out.

Two Steps to Quality

You will need to complete the performance steps prior to start measuring quality, as this is the measure of good products minus rejected products

Ingest reject counts into TilliT. For best results, you need to read local datasources with a TilliT Edge device or Integrate via API/MQTT. This can also be added via an operator completing an Activity.
