Abstract
Official abstract text for this publication.
A method includes recording a current performance signature for first and second components in a system, recording a calibrated baseline performance signature for the components, and processing the performance signatures through an aging model to determine a future performance signature for each component. The future performance signatures are processed through a system function model to determine the state of function of the system for each possible repair case. A cost-optimal repair case is then determined from among the possible repair cases, and recorded in memory. An apparatus includes first and second components of a system, and a host machine configured for processing the current and baseline performance signatures through the aging and system function models as noted above. The cost-optimal repair case is determined from among all possible repair cases, and then recorded in memory. An example system may be a cranking system with a starter motor and battery.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: receiving, from a plurality of sensors via a host machine in communication with a system having a plurality n of components, a current performance signature for the plurality n of components, wherein the plurality n includes a first and a second component, and wherein the host machine includes a processor and memory on which is recorded an aging model and a system function model; recording, via the host machine, a calibrated base…
