Abstract
The present invention generally relates to failure prediction of an infrastructure (110). A failure likelihood for one or more components of an infrastructure (110) is determined. History data (210) representing prior failures of the components of the infrastructure (110) is applied (230-250) to a Bayesian nonparametric statistical model using a beta process. Then the failure likelihood of one or more components of the infrastructure from the Bayesian nonparametric statistical model is estimated (270). Aspects of the invention include computer-implemented methods (200, 300), software and computer systems (100).
Claims15
A computer-implemented method for estimating failure likelihood of components of an infrastructure, comprising:
- accessing or receiving history data representing prior failures of the components of the infrastructure;
- applying the history data to a Bayesian nonparametric statistical model using a beta process;
- and
- estimating the failure likelihood of one or more components of the infrastructure from the Bayesian nonparametric statistical model.
A computer system for estimating failure likelihood of components of an infrastructure, the system comprising a processor that is adapted to:
- access or receive history data representing prior failures of the infrastructure;
- apply the history data to a Bayesian nonparametric statistical model;
- and
- estimate the failure likelihood of each component of the infrastructure from the Bayesian nonparametric statistical model.
