Abstract: This paper focuses on the emergency material scheduling problem after sudden natural disasters, taking into account the victims psychological distress perception and post-disaster road conditions. By referring to the scarcity theory, the victims distress function is established. With the goal of minimizing both the psychological distress cost of victims and the emergency material transportation cost, a multi-objective emergency material scheduling model under the background of sudden natural disasters is constructed. The model is solved by a rapid non-dominated sorting genetic algorithm. Finally, a case study of a certain area affected by the Wenchuan earthquake is conducted to verify the effectiveness of the model and algorithm.

Key words: emergency material distribution, deprivation theory, NSGA-Ⅱ, road state
