The time categories form the basis for the pre-defined time model. The corresponding time category can be assigned in the status mapping table. Thus, for each machine status, the time category to which the machine status belongs is defined.
In order to calculate the key performance indicators for the overall equipment effectiveness, the following time categories are available:
- Total Scheduled Time
The total number of hours available,
for example, 1 week = 168 hours - Available Production Time
The total number of hours available minus the planned downtimes,
such as breaks => 168 hours - 21 hours = 147 hours - Net Production Time
The number of hours available after subtracting the planned downtimes minus the unplanned downtimes,
such as malfunctions => 147 - (1.5 * 7) = 136.5 hours - Planned Downtime
Planned downtimes, for example, for maintenance - Unplanned Downtime
Unplanned downtimes, for example, due to damage or lack of resources
