An Asset Health Index (AHI) is a tool that processes data about asset’s condition. That index is intended to explore if alterations can be generated in the health of the asset along its life cycle. These data can be obtained during the asset’s operation, but they can also come from other information sources such as geographical information systems, supplier’s reliability records, relevant external agent´s records, etc. The tool (AHI) provides an objective point of view in order to justify, for instance, the extension of an asset useful life, or in order to identify which assets from a fleet are candidates for an early replacement as a consequence of a premature aging.
An Asset Health Index (AHI) is an asset score, which is designed, in some way, to reflect or characterize the asset’s condition and thus, its performance in terms of fulfilling the role established by the organization.
AHI represent a practical method to quantify the general health of a complex asset. Most of these as-sets are composed of multiple subsystems, and each subsystem can be characterized by multiple modes of degradation and failure. In some cases, it may be considered that an asset has reached the end of its useful life, when several subsystems have reached a state of deterioration that prevents the continuity of service required by the business.
