基于匮乏理论的应急物资调度模型构建及算法研究

Construction and algorithm research of emergency material distribution model based on deprivation

针对突发自然灾害后的应急物资调度问题,考虑灾民心理痛苦感知和灾后道路状况,引用匮乏理论建立灾民痛苦函数,以最小化灾民心理痛苦成本和应急物资运输成本为目标,构建突发自然灾害背景下的多目标应急物资调度模型,并通过快速非支配排序遗传算法对模型进行求解。最后,以汶川地震某区域为案例进行实例验证分析,验证了模型和算法的有效性。

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.
