The overall purpose of this visit is to examine and quantify, using real data, the combined effects of increasing failure frequency and severity on the scheduling of PM activities for deteriorating repairable systems. We are particularly interested in how this issue can affect the framework for analysis of successive failures in repairable systems. A prominent feature here is to model the severity, ie increasing costs of repair with ageing of equipment.To achieve this, the VF will investigate the following specific points:(i) The influence of increasing duration and frequency of corrective and preventive maintenance on the approach of analysing failure data of repairable systems.(ii) Extensions to a recent generalised non-stationary scheduling model, which is based on using a general compound process, for systems subject to PM, allowing for age-based and condition-based covariates.(iii) The application of these models to a set of pump data from the oil industry, which these collaborators have previously analysed.
