Institute for Logistics and Emergency Management, School of Economics and Management, Southwest Jiaotong University, Chengdu 610031, China) Abstract: According to the actual situation of blood supply system in post-disaster reconstruction areas and considering the dependent coefficient among blood banks, a p -medium model was developed for the facility location problem of new blood banks. And a hybrid genetic algorithm combining with tabu search is proposed to solve the model. A case study was given based on one of affected areas in Wenchuan earthquake, i.e. Aba prefecture in Sichuan province. The location results with different p value and dependent coefficients are obtained as a reference for related departments to plan the blood support system in post-earthquake reconstruction areas.
