Failure Models Indexed by Time and Usage,

Abstract

All commonly used failure models, both univariate and multivariate, are indexed by a single scale, typically time. This thesis considers the case of indexing a failure model by two scales, namely time and usage. A family of models that is indexed by these two scales of measurement, and attempts to capture the dependence between them, is developed and an example given in detail. Extensions to this basic model, and problems associated with them, are explored. As an aside, an idealised stochastic process for modelling usage is introduced. (AN)
