ARIES(Aggregate Recoverable Item Evaluation System) Model and Computer Program.

摘要

ARIES is a computerized mathematical model which assists ILS managers in their planning. It enables them to optimize recoverable item component reliabilities, maintenance capabilities, and maintenance strategies--as well as initial stockage levels for the multi-echelon base-depot supply system -- while taking into account the corresponding impact upon system availability and life cycle cost for unscheduled maintenance. Item demand is assumed Poisson. ARIES evaluates the minimized expected backorder solution to determine the expected number of NORS vehicles for both the case where complete cannibalization of parts is assumed and the case where there is no cannibalization. The ARIES solution defines the expected backorder value for each item; this parameter is a necessary input to the MSCAM model to perform refined reliability/maintainability trade-offs on the individual items. The manpower and item stockage level requirements for the individual bases and depot are determined by the ARIES solution.
