Imperfect vaccination: some epidemiological and evolutionary consequences.
An aim of some vaccination programmes is to reduce the prevalence of an infectious disease and ultimately to eradicate it. We show that eradication success depends on the type of vaccine as well as on the vaccination coverage. Vaccines that reduce the parasite within-host growth rate select for higher parasite virulence and this evolution may both increase the prevalence of the disease and prev...
متن کاملEquilibrium Selection in Evolutionary Games with Imperfect Monitoring
In this paper we analyze players’ long-run behavior in evolutionary coordination games with imperfect monitoring in a large population. Players can observe signals corresponding to other players’ unseen actions and use the proposed simple or maximum likelihood estimation algorithm to extract information from the signals. In the simple learning process we find conditions for the risk-dominant an...

متن کاملOptimizing Series Repairable Systems with Imperfect Repair
Repairable systems are either repaired perfectly to a state of as good as new or imperfectly. In this work, a system which undergoes imperfect repair is investigated. A nonlinear mathematical model is formulated for a system with the objective of finding the optimum failure and repair rate with the minimum costs subject to attaining a pre-specified performance level. Two imperfect repair models...
متن کاملRepairable systems availability optimization under imperfect maintenance
This paper deals with the modeling of a preventive maintenance strategy applied to a single-unit system subject to random failures. According to this policy, the system is subjected to imperfect periodic preventive maintenance restoring it to ‘as good as new’ with probability p and leaving it at state ‘as bad as old’ with probability q. Imperfect repairs are performed following failures occurri...
