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 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. |
|
Not scheduled |
|
All stops with Loss reason codes with the setting Exclude from schedule selected end up here. |
