Metrics and Semiparametric Model Estimating Failure Rate and Mean time Between Failures |
| 摘要 |
Techniques for predicting a failure metric of a physical system using a semiparametric model, including providing raw data representative of the physical system, to identify a set of units at risk in the physical system, a set of times of treatment corresponding to a event of at least one unit in the set of units, and an index-set of the at least one unit for which a event has occurred. A parametric and a nonparametric component of the semiparametric model are estimated and a hazard rate is predicted at a given time with the semiparametric model. |

1. A method of predicting a metric of a physical system using a semiparametric model, comprising:
providing raw data representative of the physical system; processing the raw data to identify a set of units at risk in the physical system, a set of times of treatment corresponding to a event of at least one unit in the set of units, and an index-set of the at least one unit for which a event has occurred; estimating a nonparametric component of the semiparametric model with reference to the set of units, the set of times, and the index-set; and predicting a hazard rate at a given time with the semiparametric model. |
