Alternative Methods of Base Level Demand Forecasting for Economic Order Quantity Items

摘要

The purpose of this research effort was to examine and compare five methods of base level demand forecasting which can be considered as alternatives to the present method of unweighted moving averages. All six methods, including unweighted moving averages, were evaluated according to relative accuracy in describing the actual base level demand patterns of a statistically chosen stratified sample of items managed at base level under the Air Force EOQ model. This study was exclusively concerned with expendable items which are stocked based upon DO62 EOQ procedures. Expendable items are those which are consumed in use or which lose their original identity during incorporation into, or attachment upon, another assembly. These items, commonly referred to as EOQ items, are designated by expendability, repairability, recoverability category (ERRC) codes XB2 and XB3, among others. This study was strictly limited to a sample of XB2 and XB3 items stocked by the Air Force, and present in a substantial number of base level inventories.
