four echelons humanitarian network design considering capacitated /lateral transshipment with a destruction radius and abo compatibility: tehran earthquake

During natural disasters, emergency sections try to find the best way to serve defective points and gradually find the optimal location of these service points as blood collection centers in safe areas to restore the system to its previous state. this research proposed a multi-objective mathematical model for the design of a four echelon comprehensive blood supply chain (bsc) network in earthquakes. here, the impact of the earthquake destruction radius (edr) on the bsc network and blood group compatibility have been considered simultaneously.in order to be more realistic the effect of multimodal capacitated transportation vehicles accompanied with lateral transshipment have been investigated. in our proposed model four multi-objective decision-making (modm) methods, as well as the augmented ε-constraint method is adopted for finding pareto optimal solutions. finally, the validation of the problem has been explored by bounded objective method (bom). this model has been implemented based on the real data of tehran; the capital of iran; as one of the volunteer cities for tremendous earthquake in the world.
