OEE Analysis report data

This report shows Overall Equipment Effectiveness (OEE) and its components (Availability, Performance, and Quality) by entity, and compares those metrics across similar equipment and over time. The report can also include a Utilization Loss Summary chart.

• Availability is based on the utilization events for the entity and is calculated by summing the runtime events and dividing by the sum of the runtime and downtime events. Events classified as Neither in the MES database are ignored.

• Performance is based on the actual production units on the entity compared to the estimated number of units. It is calculated by summing the good and reject production counts and dividing by the sum of the runtime events multiplied by the production rate and batch size.

• Quality is based on the good and reject production counts for the entity. It is calculated by summing the good counts and dividing by the sum of the good and bad counts.

• OEE is the product of Availability, Performance, and Quality. Note that this value is based on runtime and downtime duration and does not include times classified as Neither.

• The Utilization Loss Summary chart converts the OEE components into minutes of lost production at full capacity for each component. Note the following about the components in this chart:

  • The Availability component is the total downtime duration.

  • The Performance component is the number of minutes of lost capacity from running below the target rate. The Performance component can be negative if the entity is producing above the target rate.

  • The Quality component is the scrap counts converted to minutes of good production at the target rate.

Note the following about the report.

• The report will include rows based on the Show Details By parameter even if there is no data for the selected period. The default value for all the KPIs when no data exists is 0.

• When a shift transitions between an hour, the transition hour will have a record in both shifts. The calculation includes only data for the shift in this scenario and therefore represents less than an hour's data. On the chart, the x-axis time label for this scenario will show the hour twice, once for each shift.

• For all report variations except the Utilization Loss Summary Chart, each entity's data is shown on a separate page.

• When there is no data, the report will be blank with a No Data Available message displayed.
