The Overall Equipment Effectiveness (OEE) is a measure of productivity and efficiency that is used to evaluate the performance of a manufacturing process. It is a metric that combines the availability, performance, and quality of a production system to determine how effectively the system is being utilized. OEE is calculated by taking the product of availability, performance, and quality. Availability is a measure of how often the system is available for use, performance is a measure of how fast the system is running, and quality is a measure of how many good parts are produced compared to the total number of parts produced. OEE is an important metric for manufacturers to track, as it can help them identify areas of improvement and increase their overall efficiency. By tracking OEE, manufacturers can make adjustments to their processes to ensure that they are operating at peak efficiency and producing high-quality products.
