A refresher on Scheduled vs. Unscheduled
Almost all production occurs in “Scheduled Time” – the time during a shift.
OEE and its components (Availability, Performance, Quality) are all based on scheduled time, whereas OEE Capacity (OEEc) treats unscheduled time as a relevant factor to OEE. In your circumstance this may yield useful insights.
Further discussion of OEE can be found in PowerPoint below and other Shoplogix documentation.
...
How to calculate OEEc
To use capacity fields in Shoplogix Analytics find the “C” suffixed fields.
There is of course “OeeC”…
...
…but you’ll also find other fields with the “C” suffix
...
Any time you come across a “C-suffix” field in the analytics portal, these all relate to this same concept of unscheduled time (capacity).
How to better understand your formulas
These OEE and OEEc formulas are filtered formulas (.
This means you can right click → Use Flattened Form for to show more details) so the Is Scheduled field doesn't impact them if used as a filter.{STEVEn: include screenshot of the formula editor and Flattened Form before / after}.
...
It’s important to understand that “Is Scheduled” is toggled ON (“true”) in this formula for OEE.

This means we highly do not recommend you manually use the “Is Scheduled” field yourself. We’ve done the heavy lifting for you, and if you use any additional “Is Scheduled” filters in your dashboards, you will likely yield incorrect data. |
Filtering can strongly impact OEE and should be carefully applied. Filters like Machine and Plant can be useful.
Carefully apply filters, like State Type, because OEE will remove those components from the calculation and provide non-standard OEE results.

So what is Unscheduled Time, and why is it sometimes useful to analyze?
Production during unscheduled time is usually unexpected or unwanted when determining efficiency. Some reasons production can occur in unscheduled time include:
