Abstract:

Natural disasters pose a great threat to humanity. In order to improve the ability of disaster relief network, it focuses on pre-disaster facilities location and post-disaster capacity allocation and evacuation of disaster victims under uncertain demand. Considering two different types of disaster victims and deprivation costs, a scenario based robust optimization model is developed to minimize the expected total cost. Finally, taking the Sichuan earthquake as a case, numerical experiments and sensitivity analysis are performed to prove the effectiveness of the model and obtain some management insights. The results show that comparing with the deterministic model and stochastic programming model, p-robust optimization model can effectively enhance the cross-scenario robustness of decision-making. In addition, deprivation cost plays an important role in balancing economic benefits and psychological pain in decision-making. Expanding the capacity of emergency reserve warehouse can reduce the risk of shortages. Besides, emphasizing the evacuation of disaster victims can effectively control the deterioration of the disaster and reduce casualties.

Key words: emergency logistics, robust optimization, deprivation cost, location-allocation
