摘要

One-shot units are produced in batches and stored until use. While in storage, they are subjected to random non-estructive tests (NDTs) throughout their life horizon to determine their reliability metrics. Some of the one-shot units (with nonhomogeneous characteristics) are retrieved from storage and launched for operational use when needed. Referring to the launched units as a system, we optimize the system's operational use by determining the selected units' characteristics and their launching order. The system reliability metrics are considered in the optimum selection and launching procedure. Considering the units' inhomogeneity, we provide the confidence bounds of the probability that the system achieves a successful operation based on the optimal selection and launching order. A simulation model is developed to validate the proposed plan to optimize the units' operational use.
