Blood plasma management receives increasing concerns as it is directly related to saving lives, as a shortage could lead to high risk for overall healthcare management. Blood plasma inventory is hard to control because available donors and patients change stochastically, and blood plasma is perishable. Adequate levels of plasma need to be collected, processed and preserved, and not yield shortages or waste. In order to respond to this complex problem, one of the issues to investigate is appropriate inventory control. The Economic Order Quantity (EOQ) model is one of most powerful and flexible inventory control models. Several inventory control policies are derived from this model. For example, the continuous and periodic review policies are the two most widely used policies. The continuous review policy monitors inventory level continuously with accurate and on time inventory control, but the monitor investment is high. Periodic review policy applies only periodical control of inventory but lowers monitoring investment. In this paper, we compare applications of these inventory control policies for blood plasma inventory management. We also quantify inventory threshold values based on the system risk.
