How to Calculate Overall Equipment Effectiveness (OEE) for Facilities Management

Overall Equipment Effectiveness (OEE) is a measure of performance that identifies how well facilities management is utilizing their resources. It’s an important metric that helps to monitor the effectiveness of the maintenance process and the performance of the equipment used in the facility. Calculating OEE can be a complex process, but it is essential to understanding the effectiveness of the facilities management process.

What is OEE?

OEE is a measure of how well a facility is utilizing its resources. It’s calculated by taking into account three main factors: Availability, Performance, and Quality. Availability measures the amount of time the equipment is available for use; Performance measures how fast the equipment is running; and Quality measures the quality of the product being produced by the equipment.

Why is OEE Important for Facilities Management?

OEE is important for facilities management because it provides a clear, measurable way to track the effectiveness of the maintenance process and the performance of the equipment. By understanding the OEE of the facility, facilities managers can make informed decisions about improving the maintenance process and the performance of the equipment. This can lead to increased efficiency and cost savings for the facility.

How to Calculate OEE

Calculating OEE can be a complex process, but it is essential to understanding the effectiveness of the facilities management process. The OEE formula is: OEE = Availability x Performance x Quality. Here is a step-by-step guide on how to calculate OEE:

  1. Calculate the Availability: Calculate the total time available for production and subtract any planned downtime.
  2. Calculate the Performance: Calculate the total time available for production and subtract any unplanned downtime.
  3. Calculate the Quality: Calculate the total number of units produced and subtract any defective units.
  4. Calculate the OEE: Multiply the Availability, Performance, and Quality to get the OEE.

Conclusion

Overall Equipment Effectiveness (OEE) is an important metric for facilities management to track the effectiveness of their maintenance process and the performance of the equipment used in the facility. By understanding the OEE of the facility, facilities managers can make informed decisions about improving the maintenance process and the performance of the equipment, leading to increased efficiency and cost savings for the facility. Calculating OEE can be a complex process, but it is essential to understanding the effectiveness of the facilities management process.
