An Optimal Operational Availability Inventory Model.

Abstract

A mathematical description is given of a computer model, called the Optimal A(o) 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 supply/repair 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 A(o) Model. (Author)
