Abstract: To study the tradeoffs in patient satisfaction and system efficiency, a patient flow simulation model is developed with the incorporation of patient classification, blocking effects, and time dependent arrival and departure patterns. Performance metrics include blocking, utilization, wait times, and percentage of time at full. In the application of the model at DeKalb Medical Center, we demonstrate the value of implementing swing rooms to decrease bottlenecks and blocking within Mother Baby and Antepartum units.
Title: Routing for Blood Supply Management
 Presenting Author: Orsan Ozener,Özyegin University, Istanbul, Turkey,

Abstract: In many countries, people still die because of inadequate supply of blood products. Blood is needed for several types of treatments including organ transplants, cancer and anemia treatments, and major surgeries such as open heart surgery. In blood supply management, an important step is processing donated blood within a certain amount of time after donation. In this research, motivated by the practices in blood supply management, we study the Blood Collection Problem and develop heuristic algorithms to find good solutions.
Title: The Impact of Individual Decisions on the Equity of H1N1 Vaccine Distribution
 Presenting Author: Jessica Heier Stamm,Kansas State University, Manhattan KS, United States of America,
 Co-Author: Nicoleta Serban,Georgia Institute of Technology, Atlanta GA, United States of America,
 Julie Swann,Georgia Institute of Technology, 765 Ferst Dr, Atlanta GA, United States of America,
Abstract: We study supply chain problems motivated by response scenarios where individual decision-makers’ choices impact system outcomes. We develop models to assign users (centralization) or allow user choice (decentralization) for service sites and apply them to actual shipment data from the 2009-2010 H1N1 vaccination campaign. We compare the two systems and use spatial statistics to explain service inequity as a function of factors such as income, ethnicity and race, and service site availability.
