Go with the Flow: Improving Red Cross Bloodmobiles Using Simulation Analysis

We developed a computer simulation model to study customer service and productivity issues for Red Cross bloodmobiles. The Red Cross was concerned that excessive waiting lines and the time required to donate blood were affecting donors' willingness to make subsequent blood donations. We developed and tested several strategies for alleviating this problem including modifying set-up, staff allocation, and work rules. Initial implementation experience has resulted in significant decreases in the donor processing time and positive comments from donors citing improved speed and simplicity.
