Abstract

The transient behavior of combat logistics support systems is analyzed. Combat availability is defined as the number of active combatant platforms being supported by a single fault diagnosis and repair facility. Heavy traffic conditions inherent to intense combat periods allow the use of diffusion approximation models, which provide speedy solutions used to compare adaptive scheduling policies to a standard First-Come, First-Serve policy. The adequacy of these models is investigated and numerical solutions are compared to simulation results. The case in which failed modules require a degree of support that is beyond the capability of local maintenance is also investigated for both preand post-local-repair relocation to distant repair. The use of cannibalization in short-term situations is shown to have a dramatic effect in terms of combat availability. A preliminary model for a noncannibalization policy is also developed. Optimization models for choosing spare parts allocation within budget constraints, or for achieving required operational availability with minimum Cost are described.
