OEE: Production Metrics
See Production Unit Properties – Production Metrics for details on navigating to Production Metrics, and an overall description of production metrics configuration.
Production metrics are configured for units in the Plant Model. Right-click a unit, choose Edit [Unit] Properties, and then in the Production Unit Properties dialog box click the Production Metrics tab. In this tab, there are four more tabs:
-
Downtime
-
Efficiency
-
Production
-
Waste
The calculation of OEE requires the configuration of at least the Downtime, Efficiency and Production tabs. Prior to configuring Production Metrics for OEE, ensure that you have set up:
-
Products and production rate specifications
You can also configure alarms to fire based on specification limits in any or all of the Production Metrics areas. For further information, see Production Unit Properties: Production Metrics.
Downtime Tab
The OEE downtime categories—Unavailable Time and Outside Area—are attached in the Downtime tab.
-
In Unavailable Downtime Category, choose Unavailable Time.
-
In External Downtime Category, choose Outside Area.
-
In Availability Downtime Percent, choose the variable you configured with a target the downtime specification.
Efficiency Tab
-
Ensure that Use Standard Efficiency Calculation is selected. The other option, Use Efficiency Calculation Variable, is used if you derive OEE from a custom calculation stored in a variable. For further information, see Production Unit Properties: Production Metrics.
Production Tab
-
If production events have been configured for this line or unit, select Production is Accumulated From Event Dimensions. If you have configured a variable to collect gross production amount data, select Production is Accumulated from a Variable.
-
If you assigned some reasons to the Performance Downtime category as you set up your reason tree, choose it from the list in Performance Downtime Category.
Performance Downtime factors into OEE by including speed changes in downtime calculations. This is useful in cases where a line does not actually go down, but rather slows by varying degrees from its target performance. For more information, see OEE Time Categorization.
Performance Downtime is optional and is used if you have a method for tracking minor stops or other issues involving speed decreases.
-
In Production Rate Specification, choose the specification variable in which you set up the target for ideal production rate by product. For more information, see Specifications.
-
In Production Rate Time Units, select the unit of time corresponding with the Production Rate Specification in the previous step.
