Competing risks for repairable systems: A data study
We analyse a dataset from the Offshore Reliability Data (OREDA) Database, looking for a model, which can be used to unveil aspects of the quality of the maintenance performed. To do so we must investigate the mathematical modelling of maintenance and repair of components that can fail due to a variety of failure mechanisms. NOTE! UNTIL WE GET A “GO” FROM THE OREDA PROJECT THE DATA IN Table 1 SH...
متن کاملThe Identifiability Problem for Repairable Systems Subject to Competing Risks
Within reliability theory, identifiability problems arise through competing risks. If we have a series system of several components, and if that system is replaced or repaired to as good as new on failure, then the different component failures represent competing risks for the system. It is well known that the underlying component failure distributions cannot be estimated from the observable da...
متن کاملCompeting risks regression for clustered data.
A population average regression model is proposed to assess the marginal effects of covariates on the cumulative incidence function when there is dependence across individuals within a cluster in the competing risks setting. This method extends the Fine-Gray proportional hazards model for the subdistribution to situations, where individuals within a cluster may be correlated due to unobserved s...
متن کاملSemi-Competing Risks Data Analysis
Hospital readmission is a key marker of quality of healthcare; it has been used to investigate variation in quality among patients in a broad range of clinical contexts and has become an important policy measure. Notwithstanding its widespread use, however, readmission remains controversial as a measure of quality. Among the concerns raised, whether and how patient deaths are handled in the ana...
متن کاملParametric Estimation in a Recurrent Competing Risks Model
A resource-efficient approach to making inferences about the distributional properties of the failure times in a competing risks setting is presented. Efficiency is gained by observing recurrences of the compet- ing risks over a random monitoring period. The resulting model is called the recurrent competing risks model (RCRM) and is coupled with two repair strategies whenever the system fails. ...
