Test of a System Which Considers the Priority Allocation of Spare Recoverable Components

Abstract : Under a previous task the Logistics Management Institute (LMI) developed a conceptual model for the Air Force which allows military essentiality considerations to be reflected in budgets and procurement plans for recoverable (repairable) aircraft components. Using the model, spares can be procured so that the number or percentage of operational units of the different weapon systems tend to be in the best balance obtainable under any or all procurement funding constraints. The report describes tests by which the LMI model was compared with a marginal analysis requirements determination model planned by the Air Force for their evolving Advanced Logistics System. Tests showed that solutions from the LMI model are optimal, considering the mathematical assumptions common to the two models, and that solutions from the currently planned model are not.
