Summary

1. The RAND National Defense Research Institute examined Department of Defense depot-level reparable (DLR) supply chain management to assess how it could be improved to enhance customer support and reduce costs. This report concludes that DLR supply chain management appears to be done relatively effectively across the services. What on the surface appears to be substantial inventory excess and high disposals of assets is instead a reflection of the fact that DLRs are durable assets very much like weapon systems and other end items. Most DLRs have very low condemnation rates, with depot maintenance economically repairing them time and again through the life of the supported end item. So when they are replaced by upgraded versions or weapon systems are phased out, demand disappears but the assets remain, leading first to "excess" inventory and then to disposals. This is a cost of doing business. As a result, no large, "silver bullet" solutions were found. Still, a number of modest opportunities for improving DLR supply chain management were identified. The first is improving parts supportability, including taking a total cost perspective that encompasses supply and maintenance costs when planning inventory in support of depot production. The second is to shift the Army more toward pull production. The third is to reduce lead times for all types of contracts affecting DLR supply chain management. And the fourth is to better account for all resource lead times in planning DLR production and for anticipatable shifts in procurement and repair needs. All of these enhancements would improve customer support, with better parts support likely reducing maintenance costs and pull production reducing the buildup of inventory.
