This paper is concerned with evaluating the impact on weapon system availability of component and assembly redundancy. The evaluation must be efficient, and it must be possible to integrate the evaluation into multi- echelon stockage models whose objective is to fund the least cost mix of stockage consistent with the availability goals for weapon or other type systems. The mathematics to be discussed here provides a rigorous solution to the evaluation problem when there is only a single supply echelon there can be upper echelon repair, but not supply, unless the supply is from a perfect supplier, always in stock. For the more general multi-echelon case, approximate approaches are presented. Keywords Inventory models, Operational readiness, Operations research.
