Overall equipment effectiveness (OEE) is a performance metric that is commonly used in manufacturing and industrial settings to measure the efficiency of equipment. OEE measures the equipment’s effectiveness in terms of its availability, performance, and quality. The formula for calculating OEE is:

OEE = Availability x Performance x Quality


Availability: The percentage of time that the equipment is available for production. It takes into account factors such as breakdowns, changeovers, and planned maintenance.
Performance: The ratio of the actual production rate to the theoretical production rate. It takes into account factors such as machine speed, operator efficiency, and quality of materials.
Quality: The percentage of good products produced compared to the total number of products produced.
OEE is typically expressed as a percentage, with 100% indicating perfect performance. A high OEE score indicates that the equipment is being used effectively, while a low OEE score indicates that there is room for improvement.

OEE can be used to identify areas of improvement in the production process. By analyzing the factors that contribute to low OEE scores, manufacturers can make changes to improve the efficiency and effectiveness of their equipment. This can lead to reduced downtime, improved product quality, and increased productivity.
