Approved for public release, distribution is unlimited / .08B in shipping and redistribution costs of Not Ready for Issue (NRFI) materiel. This thesis models the NAVICP shipping of unserviceable but repairable (retrograde) Navy materiel or Depot Level Repairables (DLRs). It develops an integer linear program to prescribe minimum cost shipment recommendations of DLRs from fleet to repair locations within the NAVICP and Defense Logistics Agency (DLA) distribution system subject to constraints on average shipping time (AveTime). NAVICP provided data on DLR shipments for one year from which we construct six representative DLRs, 3 of aviation and 3 of maritime cognizance. We find a cost and time savings can be achieved for all representative DLRs by avoiding the use of DLA as storage prior to induction for repair. In this study we compare shipping costs for each of the six DLRs when we constrain AveTime, from 2 to 8 days. We find 2-day constrained AveTime shipping, on average, costs 18 times that of 7-day AveTime shipping, twice that of 3-day shipping and a minimum of 5 times and a maximum of 11 times that of the costs of 4 through 6-day shipping. / Lieutenant Commander, United States Navy
