How is the System Structured and What Are Its Key Components?
In the OEE system, different configurations are used to structure and monitor production efficiency at various levels.
Here's a breakdown of how these elements relate to each other and their distinct roles:
- Plant – The highest level in the hierarchy, typically representing the country where the chips production facility operates. It provides a broad organizational structure to group all business locations under one entity.
- Business Unit – Represents a specific business location, such as a city or neighborhood address. A chips company may have multiple business units within the same country or city, each operating independently at different addresses. For smaller organizations, a single business unit may be used across multiple work centers.
- Facility – Refers to the physical building where production activities take place. A chips factory may have different facilities for various operations, such as a Production Facility for frying and cutting potatoes and a separate Packaging Facility for bagging the chips. Facilities can be named based on their function or location, such as Production Building, Packaging Building, or Building A.
-
Area – A designated physical location within a facility that houses one or more work centers. For example, within a chips factory:
- The Cutting Area is where potatoes are sliced into chips.
- The Frying Area is where the sliced potatoes are cooked.
- The Seasoning Area is where flavors are added.
- The Packaging Area is where finished chips are placed into bags.
-
Work Centre – The smallest unit where OEE is measured. It can be an individual machine, a production line, or a production cell. In a chips factory, a work center might refer to:
-
- A Potato Slicer that cuts potatoes into thin slices.
- A Frying Machine that cooks the chips.
- A Packaging Line that fills bags with chips and seals them.

How OEE Tracking Can Be Configured.
OEE tracking can be performed at different levels, depending on the production structure and the desired level of detail:
- Full Line Performance: Monitoring overall production by placing a counter at the bottleneck (the slowest process) to measure how many bags of chips are produced per minute.
- Individual Equipment Performance: Tracking downtime or inefficiencies at a specific machine, such as measuring how often the Potato Slicer gets jammed.
- Final Product Output: Measuring how many finished packs of chips are produced.
- Intermediate Product Tracking: Monitoring key production stages, such as counting how many sliced potatoes reach the Frying Machine.
- Rejects & Waste Monitoring: Measuring raw material waste or defective chips, ensuring better quality control.
