A preventive maintenance model, caller FNBM(α,δ,γ)model, is proposed to decide an optimal repair number under achieved availability requirements(r) along with taking two types of failures(repairable or irrepairable) into account.
In this model, the current system is replaced by a new one in case when it doesn't meet the achieved availability requirement, even though it is repairable failure; Otherwise it is replaced in time of the first irrepairable failure.
Assumed that the j-th failure is repairable with probability ., minimal repairs are allowed for repairable failure between replacements. Expected cost rate for preventive maintenance model is developed using NHPP(Non-Homogeneous Poisson Process) in order to determine the optimal number ., also numerical examples are shown in order to explain the proposed model.
Since the proposed FNBM(α,δ,γ)model includes Park FNBM model(1979) and Nakagawa FNBM(p)model(1983) this proposed model is thought to be better than previous model, especially for weapon system which requires availability as primary parameter.
