Depot Level Maintenance Forecasting Techniques
Abstract
The Economic Order Quantity (EOQ) Buy Budget Computation System (D062) includes two techniques to forecast consumable parts needed to support depot level maintenance (DLM). One method uses future end-item DLM program projections and replacement percent data. The other method simply uses past depot demand history. Item managers seldom use the DLM program projections to determine future EOQ requirements, and instead rely on past history. For example, the projected DLM program was used for only 1 percent of the EOQ items at Ogden ALC. We initiated this study to determine which method was more accurate. We compared the two consumable forecasting techniques available in D062. Initially, we used the acquisition advice code to identify consumable items actually used in support of depot level maintenance. However, we found many cases where this code was inaccurate. So, instead of using this code, we decided to group the items two different ways to do our analysis. The first grouping included all consumable items where D062 computed DLM program requirements. The second grouping included items where DLM projections were actually used in the requirements computations. For each grouping we compared the two forecasting techniques to the actual demands.
