This study determined that …


A Study Of Defense Logistics Agency Inventory Classifications: Application Of Inventory Control Methods To Reduce Total Variable Cost And Stockage Levels, Wayne C. Goulet, Michael L. Rollman Sep 1996

A Study Of Defense Logistics Agency Inventory Classifications: Application Of Inventory Control Methods To Reduce Total Variable Cost And Stockage Levels, Wayne C. Goulet, Michael L. Rollman

Theses and Dissertations

This thesis analyzes the financial impact of applying a single inventory requirements model to three separate classes of inventory at the Defense Logistics Agency's (DLA) Defense Supply Center-Columbus (DSCC) commodity management facility. DLA' 5 blanket application of its variation of the Economic Order Quantity (EOQ) requirements model may not be appropriate for all levels of demand, possibly suboptimizing DLA's desire to minimize inventory costs while still providing an appropriate level of customer service. Simulation analyses of the DLA EOQ requirements model, the Silver-Meal heuristic, and Periodic Order Quantity models were conducted to examine which dynamic lot-sizing model is more effective …
