A significant challenge facing the Air Force Medical Service AFMS Military Treatment Facilities MTFs is the perishability costs associated with its pharmaceutical stock. During a two year time period, the AFMS returned expired or nearly expired pharmaceuticals valued at over 23,000,000. In response to the waste represented by pharmaceutical perishability cost, this thesis analyzes the historical inventory management decisions of 173 MTFpharmaceutical combinations and proposes an alternative inventory control policy to reduce perishability costs. Based on the critical nature of pharmaceuticals and importance of generating high patient satisfaction, the proposed alternative inventory control system was required to be cognizant of the cost savingsservice level trade-off. After applying a fundamental inventory management equation to historical patient demands, the calculated inventory control policy is evaluated against a recent nine month time period of patient demand in terms of potential cost savings and fill rates. At the conclusion of the study, it is determined that the use of the proposed inventory control policy would generate an effective perishability cost savings of approximately 250,000 annually, as well as a one-time inventory reduction cost savings that exceeds 1,700,000. In spite of this stock reduction, the studied MTFpharmaceutical combinations would maintain a strong fill rate that exceeds 99.82.
