This memorandum describes the initial results of a digital computer program that considers repair characteristics and unit cost by item in the computation of item stock levels. These levels will achieve a specified aggregate base fill rate across all recoverable items with the least dollar investment in base recoverable inventory. The test consisted of taking demand data for a sample of 2802 recoverable items at Andrews Air Force Base and using the first six months of data as model input to compute item stock levels required to achieve a range of aggregate base fill rates. Demands for these items for the next six months were then compared with these stock levels. It was found that the actual fill rates differed by less than 5 percent from the target fill rates that had been used in setting the stock levels. The most important result of the present study is the method which uses both repair characteristics and unit cost to analyze stock requirements across a large group of items.
