An Analysis of the Blood Bank Whole Blood Inventory Control

The whole blood inventory control model is developed, shown to provide an accurate representation of actual blood bank operations in Korea. The main difference of the blood bank situations between Korea and the United States is that about 50 percent of all bloods demanded, crossmatched, and held for a particular patient are eventually found not to be required for that patient in case of U.S. while in Korea the crossmatch test is not so significant and almost successful. Accordingly, the model in this paper is focused in seeking the minimum inventory level where neither shortage nor outdating bloods begin to occur, while the Jennings' model, developed in 1970 at MIT OR Center, is the inventory level somewhere between the inventory level 'band' where both shortage and outdating occur.
