Stochastic Intensity for Minimal Repairs in Heterogeneous Populations
In this note we revisit the discussion on minimal repair in heterogeneous populations in Finkelstein (2004). We consider the corresponding stochastic intensities (intensity processes) for items in heterogeneous populations given available information on their operational history, i.e. the failure (repair) times and the time since the last failure (repair). Based on the improved definitions, the...
متن کاملLikelihood Estimation for Stochastic Epidemics with Heterogeneous Mixing Populations
We consider a heterogeneously mixing SIR stochastic epidemic process in populations described by a general graph. Likelihood theory is developed to facilitate statistic inference for the parameters of the model under complete observation. We show that these estimators are asymptotically Gaussian unbiased estimates by using a martingale central limit theorem. Keywords—statistic inference, maximu...

متن کاملStochastic modelling of infectious diseases for heterogeneous populations
BACKGROUND Infectious diseases such as SARS and H1N1 can significantly impact people's lives and cause severe social and economic damages. Recent outbreaks have stressed the urgency of effective research on the dynamics of infectious disease spread. However, it is difficult to predict when and where outbreaks may emerge and how infectious diseases spread because many factors affect their transm...
متن کاملStochastic analysis of preventive maintenance in heterogeneous populations
Many different types of preventive maintenance policy have been defined in the literature and implemented in reliability practice. However, almost all models, procedures, and approaches deal only with the case when items come from homogeneous populations. In this paper, we analyze the effect of preventive maintenance on the reliability characteristics of items selected from heterogeneous popula...
