Reason tree
The reason tree is a structured representation of the different states in which a machine or plant can be. OEE is a tool for continuous improvement, and a crucial step towards improvement is the analysis of the reasons for downtimes of machines and plants. You can improve the performance of a plant by identifying the root causes of downtimes, such as late delivery to stations. To enable this analysis, you need a detailed catalog of fault reasons, the reason tree.
The reason tree is based on the specified time categories:
-
Production time (Net Production Time)
-
Planned downtime (Planned Downtime)
e.g. maintenance
-
Unplanned downtime (Unplanned Downtime)
e.g. machine fault, material shortage
A fault reason (reason) corresponds to a time category.
In the reason tree you define detailed fault reasons according to your requirements and experience. Five levels of detail are available.
The reasons you have created are available when creating an OEE dashboard, when editing a status assignment, and for the formula for calculating a KPI type.
The reason tree and the created fault reasons (Reasons) apply to the entire tenant.
