Abstract
Distress models can be generated to model current or future deterioration of components. By correlating distress models with maintenance costs and material consumption, cumulative cost models and cumulative material models can be developed to optimize engine removal timing in order to maximize asset and portfolio value.
Claims20
A system, comprising:
- a processor that executes computer-executable instructions stored in a memory, which cause the processor to:
- receive data from a set of engine components;
- estimate, based on the data, distress levels of the set of engine components and a number of distress-accelerating exposures experienced by the set of engine components;
- generate a cumulative cost model (CCM) that forecasts a difference in cost between servicing the set of engine components at a current time and servicing the set of engine components at a later time, wherein the CCM is a function of the distress levels, the number of distress-accelerating exposures, and historic labor and material costs;
- and
- schedule servicing for the set of engine components based on the CCM.
A computer-implemented method, comprising:
- receiving, by a device operatively coupled to a processor, data from a set of engine components;
- estimating, by the device and based on the data, distress levels of the set of engine components and a number of distress-accelerating exposures experienced by the set of engine components;
- generating, by the device, a cumulative cost model (CCM) that forecasts a difference in cost between servicing the set of engine components at a current time and servicing the set of engine components at a later time, wherein the CCM is a function of the distress levels, the number of distress-accelerating exposures, and historic labor and material costs;
- and
- scheduling, by the device, servicing for the set of engine components based on the CCM.
A computer program product for predicting maintenance costs or material consumptions, the computer program product comprising a non-transitory computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
- receive data from a set of engine components;
- estimate, based on the data, distress levels of the set of engine components and a number of distress-accelerating exposures experienced by the set of engine components;
- generate a cumulative cost model (CCM) that forecasts a difference in cost between servicing the set of engine components at a current time and servicing the set of engine components at a later time, wherein the CCM is a function of the distress levels, the number of distress-accelerating exposures, and historic labor and material costs;
- and
- schedule servicing for the set of engine components based on the CCM.
