A Blood Supply Chain Optimization Model to Determine Optimal Collected Blood and Vehicle Routing Considering Demand Shortage

This paper discusses the development of an optimization model involving four echelons: donor, blood center, blood mobile and hospital. The blood collection can be done at the blood center and the blood mobile. The blood mobile should determine its optimal routing in order to collect the blood from each city to minimize the total relevant cost. All collected blood are pooled in blood center which then deliver the blood to the hospitals in satisfying the demand. To assist the distribution of blood from the blood mobile to the blood center, this article also discusses the usage of shuttle and blood mobile that can be utilized on a daily basis. This research aim to reduce blood supply chain cost by develops a mix integer linier programming. The model also considers the blood shortage of blood in the hospital due to unsatisfied demand.
