Designing blood supply chain network in disaster situation considering blood groups and expiration date

The purpose of this paper is designing blood supply chain network in disaster situation considering blood groups and expiration dates. In the proposed network, there are blood collection centers, labs for quality assurance and producing blood products, and hospitals. Donors refer to blood collecting centers. These centers receive blood from donors and transfer to labs. After required tests, labs send blood products to hospitals. In the proposed model of this study, a blood product, i.e. plasma is considered. The proposed model is a MIP model which minimizes the total cost of the network, including: the establishment cost of facilities, cost of transportation, and cost of holding inventory. Furthermore, uncertainty in demand has been considered using different scenarios. Moreover, in order to meet the demand, blood groups and plasma expiration date have also been investigated. Finally, the efficiency of the proposed model is investigated using random problems in different dimensions.
