Abstract
In response to emergencies, it is critical to investigate how to deliver emergency supplies efficiently and securely to disaster-affected areas and people. There is no doubt that blood is deemed one of the vital relief supplies, and ensuring smooth blood delivery may substantially alleviate subsequent impacts caused by the disaster. Taking red blood cell products as the research object, this work proposes a four-echelon blood supply chain model. Specifically, it includes blood donors, blood donation houses, blood centres, and hospitals. Furthermore, numerical analysis is provided to test the feasibility of blood collection and distribution schemes and conduct sensitivity analysis to test the impacts of the relevant parameters (e.g., apheresis donation proportion of red blood cells (RBCs), distance between blood donors and blood facilities, and times of blood donation) on the scheme. This research provides some scientific and reasonable support for decision makers and managerial implications for emergency departments and contributes to the study of emergent blood supply chain.
Highlights
As multidimensional conflicts in politics, economy, and environment become increasingly evident, the world has witnessed an increase in the number of natural and manmade disasters
Lingo is introduced to solve the model to obtain the number of open blood donation houses and blood collection in each period, as shown in Table 8
Conclusions. is study focuses on blood supply chain operation-related problems in emergencies. It proposed a four-echelon blood supply chain model consisting of blood donors, blood donation houses, blood centres, and hospitals
Summary
As multidimensional conflicts in politics, economy, and environment become increasingly evident, the world has witnessed an increase in the number of natural and manmade disasters. Ese occurrences cause considerable human casualties and economic losses and impose dramatic negative impacts on people’s psychological states and lives In this context, the response to such complex emergent events requires a normative response-guaranteed system. E aim of this study is to explore the optimal operations of a multinode and four-echelon blood supply chain in emergency, based on the status quo of emergency rescue in China. With respect to these literatures, it highlights that this work expands the previous research model of blood supply chain in several aspects, such as the selected targets, supply chain layers, dynamic stochastic demand, and blood collection and distribution models.
