Estimating remaining usage of a component or device

A computer-implemented method of remaining usage estimation, the computer-implemented method comprising:

• receiving measurement data indicative of a level of usage of an asset;
• accessing first and second model data of the asset, the first model data including discrete probabilities of a first set of respective remaining usage (RU) values, the second model data including measurement levels matched to a second set of respective RU values;
• processing, by one or more processors, the first model data by neglecting a selected portion of the discrete probabilities of the first set of RU values, the selected portion corresponding to RU values less than the level of usage indicated by the measurement data;
• and
• determining an RU estimate of the asset based at least on the processed first model data and the second model data.

A machine-readable storage medium embodying instructions that, when executed by a machine, cause the machine to perform operations comprising:

• receiving measurement data indicative of a level of usage of an apparatus;
• accessing first and second model data of the apparatus, the first model data including discrete probabilities of a first set of respective remaining usage (RU) values, the second model data including measurement levels matched to a second set of respective RU values;
• updating the first model data by neglecting a selected portion of the discrete probabilities of the first set of RU values, the selected portion corresponding to negative RU values;
• and
• generating an RU estimate of the apparatus based at least on the updated first model data and the second model data.
