Patent ID: 8903750

Claim:
A method of estimating a remaining useful life (RUL) of a first apparatus, comprising: obtaining, by a computer device, first a priori RUL data describing first a priori RUL values that each identify a different a priori RUL of the first apparatus as a function of time over a first time period; defining a first plurality of buckets within the first a priori RUL data, each of the first plurality of buckets corresponding to a different set of the first a priori RUL values among a first plurality of sets of the first a priori RUL values such that each of the first plurality of sets corresponds to a different one of a first plurality of time segments in the first time period; obtaining a first operational event indicator that indicates a current operational event of the first apparatus; and determining a first plurality of probability values based on the first operational event indicator, wherein each of the first plurality of probability values quantifies a probability that a current RUL value identifying a current RUL of the first apparatus is within a different one of the first plurality of buckets.
