Abstract

A maintenance system for maintaining a hardware system is described. The maintenance system includes an acquisition circuit and an analysis circuit. The acquisition circuit can be configured to acquire a plurality of operational parameters of the hardware system, the plurality of operational parameters being relevant to a health state of the hardware system. The acquisition circuit can be configured to forward the plurality of operational parameters to the analysis circuit. The analysis circuit can be configured to determine a device health score for the hardware system, a remaining useful life of the hardware system, and/or a user recommendation for operating the hardware system, each based on the plurality of operational parameters. Further, a method of analyzing and/or creating health information for a hardware system is described.
