Army Logistics: Better Management of the Army's Unserviceable Inventories Could Save Millions : U.S. Government Accountability Office , November , 1990
U.S. Government Accountability Office
From the summary: "As of September 1989, the Army’s unserviceable inventory of spare and repair parts totaled about $5.1 billion (“unserviceable” assets are defined as assets that need to be repaired). This inventory has increased by about 50 percent from fiscal years 1985 to 1989. Repairing assets is often less costly and less time-consuming than purchasing replacements to support operational and combat-readiness requirements. Thus, the Army can minimize its inventory investment costs and enhance readiness by reusing its unserviceable stock more often,"
