The purpose of this thesis is to assess the applicability of the Graham Decision Model for Spare Parts, a process flow chart developed by Lieutenant Ruth Graham, United States Navy, to the wholesale replenishment of communication and electronic repair parts by the Purchasing Division, Directorate of Contracting, Sacramento Army Depot, United States Army Depot Systems Command. The model was developed to be used as a decision tool by Department of Defense item managers and acquisition managers in identifying repair part candidates for Life Cycle Costing. This thesis tests the applicability of the decision model using selected communication and electronic repair parts. The researcher found that Life Cycle Cost factors are not considered during the wholesale replenishment of repair parts at the depot or inventory control point level. The researcher found that performance data are neither available to, nor determinable by, the user of the model in order to fully apply the model and make Life Cycle Costing decisions. The researcher proposes that performance data be collected by the inventory control points through the Commodity Command Standard System for use in Life Cycle Costing decisions. Additionally, the researcher proposes modifications to sequencing of the criteria used in the Graham Decision Model for Spare Parts and recommends two additional criteria for use in the decision process at the Sacramento Army Depot.
