A summary of replacement models with changing failure distributions. (English) Zbl 0691.90027

This article proposes a replacement model where a unit is replaced by a new one either at failure or at a specified number n of events, whichever occurs first. During each period between events, the unit is assumed to have varying failure distributions. The author deals with the problem of finding the optimum number N* that minimizes the long run expected cost rate. Four special cases where the events are faults, intermittent uses, preventive maintenances and shocks are discussed.
