A holistic approach to Overall Equipment Effectiveness (OEE)

摘要

The effective operation of individual pieces of production equipment, assembly lines, or whole factories is dependent on three dimensions of performance, 1. The amount of time that it is available to run (Availability) 2. The speed of the equipment (Performance Rate) 3. The quality of the product that it produces (Quality Rate) Equipment that is operating effectively scores highly on each of the above dimensions. If these metrics are viewed in isolation, they provide a valuable insight into the performance of the equipment, but the compound effect of all three of the dimensions provides surprising results. The compound effect (fig 1) is called the Overall Equipment Effectiveness (OEE) and is obtained by simply multiplying the Availability by the Performance Rate and the Quality Rate.
