Where different losses end up in the OEE model
This page provide an understanding of what opportunities exist to control where in the OEE-model different losses end up depending on settings and reason codes.
The OEE-model is well visualized in the Loss model report
The illustration can either be followed
from the top (OEE loss) and down towards registration
or, from down registration and up towards OEE loss.
Quality losses come from scrap registrations.
The amount of OEE loss is calculated as
= scrapped amount x optimal cycle time
Activating Calculate rework as quality loss means that rework is also included in Quality loss.
Performance loss (Speed losses)
Speed losses come from cycles that are too long, but do not exceed Longest cycle time. See more about Uptime, downtime and cycle times in RS Production.
As long as Calculate rework as quality loss is not activated, rework is included in Performance losses (speed loss).
Performance loss (Microstops)
If Calculate microstops as speed loss is activated, microstops are included in performance losses (microstops).
Availability losses (other)
All stops that are not given a specific configuration end up here.
As long as Calculate microstops as speed loss is not activated, microstops are included in Availability losses (other).
Technical availability losses
All stops with Loss reason codes of the Machine related category end up here.
Excluded from OEE
All stops with Loss reason codes with the setting Exclude from OEE selected end up here.
All stops with Loss reason codes with the setting Exclude from schedule selected end up here.
