应急物资联合配送决策研究

救援物资的高效投放是应急物流的关键活动之一。考虑到灾后救援车辆短缺,分配时受灾群众产生非理性心理,以及灾后道路状况对军、地救灾车辆速度产生影响等因素,本文从军民融合的角度出发,根据军地运输车辆特点,设计科学合理的车辆分配方案与运输路线。论文研究构建了基于车辆分配公平性和应急配送及时性的“分配-运输”集成决策模型,设计改进后的NSGA-Ⅱ算法进行求解,最后通过算例验证本算法的有效性和合理性,并通过调节军民运输车辆数,找到应急救援过程中的最佳军、地车辆比例,从而为灾后各灾备中心的车辆调度决策提供参考。

Research on Decision-making for Joint Distribution of Emergency Materials

The efficient delivery of relief supplies is one of the key activities of emergency logistics. From the perspective of military-civilian integration, this article designs a scientific and reasonable vehicle allocation plan and transportation route based on the characteristics of military and civilian transportation vehicles. In addition, factors such as the irrational psychology of the affected people and impact of road conditions on the speed of different vehicles will be considered. In a word, the paper constructs an “allocation-transportation” integrated decision-making model based on vehicle allocation fairness and emergency dispatching timeliness. And a NSGA-II algorithm is improved to solve the problem. Finally, an example is used to verify the effectiveness and rationality of the algorithm. By adjusting the number of military and civilian transport vehicles, the optimal ratio of military and local vehicles in the emergency rescue process is found, which provides reference for vehicle dispatching decisions of distribution centers after the disaster.
