Benchmark | Definition of Benchmark by MerriamWebster. Availability has various meanings and ways of being computed depending upon its use. Availability is defined as "a percentage measure of the degree to which machinery and equipment is in an operable and committable state at the point in time when it is needed."
equipment itself, the process being performed, and the surrounding facilities and operations. It has various meanings and ways of being computed depending upon its use. 3. Availability Classifications The definition of availability is somewhat flexible and is largely based on what types of downtimes one chooses to consider in the analysis.
Overall equipment effectiveness (OEE) is a measure of how well a manufacturing operation is utilized (facilities, time and material) compared to its full potential, during the periods when it is scheduled to run. It identifies the percentage of manufacturing time that is truly productive. ... (Availability)*(Performance)*(Quality) Using the ...
Equipment Availability. Definition: "Equipment Utilization" measures the percentage of time a piece of equipment is actually operationally in a 24 hour day, for a given period of time.The performance measurement is the productive time expressed as a percentage of the total time available. Responsibility: The reporting of Equipment Utilization is the responsibility of the Production Controller.

Availability, reliability, maintainability, and capability are components of the effectiveness equation. The effectiveness equation is a figure of merit which is helpful for deciding which component(s) detract from performance measures. In many continuous process plants the reliability component is the largest detractor from better performance.
Defining World-Class. OEE is the ratio of Fully Productive Time to Planned Production Time (refer to the OEE Factors page for a graphical representation). It is calculated as the product of its three constituent factors:. OEE = Availability × Performance × Quality. The nature of this calculation makes achieving a high OEE score quite challenging. For example, if all three factors are 90% ...
