This guide is designed to assist you in utilizing the OEE reports to maximize your production efficiency.
What is OEE (Overall Equipment Effectiveness)?
OEE is a key performance indicator used in manufacturing to measure the efficiency and effectiveness of production processes. It provides a comprehensive view of how well a manufacturing operation is performing relative to its full potential during the periods when it is scheduled to run. OEE is expressed as a percentage, with 100% representing perfect production, meaning manufacturing only good parts, as fast as possible, with no downtime.
How is OEE Calculated?
OEE is calculated by multiplying three key factors: Availability, Performance, and Quality. Each of these factors addresses a different aspect of the manufacturing process:
Availability: This measures the percentage of scheduled time that the equipment is available for production. It is calculated as:
Availability = Run Time / Planned Production Time
where Run Time is the actual time the equipment is running and Planned Production Time is the total time the equipment is scheduled for production.
Performance: This measures the speed at which the equipment operates as a percentage of its designed speed. It is calculated as:
Performance = ( Ideal Cycle Time × Total Count ) / Run Time
where Ideal Cycle Time is the fastest cycle time that the equipment can achieve, and Total Count is the number of units produced.
Quality: This measures the percentage of good parts produced out of the total parts produced. It is calculated as:
Quality = Good Count / Total Count
where Good Count is the number of units that meet quality standards.
The overall OEE score is then calculated by multiplying these three factors:
OEE = Availability × Performance × Quality
By monitoring and improving OEE, manufacturers can identify and eliminate inefficiencies, leading to higher productivity and better utilization of their equipment.
OEE Report
Access the OEE report from the menu Reports > Efficiency > OEE
By default it shows a graph day view off OEE, by production area.
You can can to a table view by changing the View to Table
This shows more detailed OEE, availability, performance and quality data by day.
