Abstract:

A mathematical description is given of a computer model, called the Optimal Ao Model, designed to maximize equipment operational availability subject to a budget constraint for spares procurement. Levels are calculated for all items in the equipment parts breakdown and all activities in a multi-echelon supplyrepair system. A solution procedure is given based upon the Lagrange multiplier approach with an embedded dynamic programming technique. A description is also given of the Material Flow Model designed to calculate parameters of the Optimal Ao Model. Author
