Abstract One-shot systems, such as military weapons, airbags, or fire extinguishers, contain two types of components: electronic components (ECs) where a failure occurs randomly, and chemical components (CCs) whose failure can only be identified by destructive inspection. An acceptance sampling method is considerd for the destructive inspection. In view of the particularity of the CCs, two different inspection policies are proposed: a general inspection policy which only considers the destructive inspection, and a two-stage inspection policy which considers both the nondestructive and destructive inspection. A discrete event simulation is developed to estimate the interval availability and life cycle cost. A chaos genetic algorithm (CGA) is used to find the global optimal inspection intervals, sample sizes, and two acceptance numbers to minimize the life cycle cost and satisfy the target of interval availability.
