Asset Availability is a measure of the amount of time a piece of equipment or machinery is available for use. It is a key metric in maintenance operations and management, as it helps to determine the effectiveness of maintenance activities and the overall performance of the asset. Asset Availability is calculated by dividing the total time the asset is available for use by the total time it is expected to be available. This metric is used to identify areas of improvement in maintenance operations and to ensure that assets are being used efficiently and effectively. Asset Availability is closely related to other metrics such as asset reliability, asset utilization, and asset performance.
