Determining overall equipment effectiveness

Overall equipment effectiveness, or OEE, is a metric that's used in manufacturing to measure how efficiently production resources are being utilized versus their maximum potential. OEE is actually a combination of three other metrics: availability, performance, and quality. Availability is a measure of uptime. 100% availability means that resources are available for all of their scheduled operational time. In other words, there's no unscheduled downtime. Performance is a measure of production speed or capacity. 100% performance means that production is occurring at maximum speed or capacity. Quality is a measure of the production of good parts versus bad parts. 100% quality means that only good parts are being produced. Availability, performance, and quality are measured as percentages, and OEE is simply the product of multiplying...
