【摘要】：地震灾害是所有自然灾害中给人类社会造成损失最为严重的地质灾害。地震灾害应急救援是一项复杂的系统工程,其中应急救灾物资的配送更是救援工作中的重要环节,高效的配送将有利于保障人民生命安全,大大减少地震带来的严重损失,因此针对地震灾害应急物资配送路线的研究是十分必要的。本文以昭通市地震应急物流为研究背景,首先对该市市情、地震灾害历史以及地震应急物流现状进行分析,发现昭通市在地震灾害应急物资配送中存在的问题,进而着手研究地震应急配送路线模型及算法,为解决问题提供方法。基于地震应急配送需具备的时效性、弱经济性、动态性等特点,本文引入关键节点,将动态应急配送路线问题转化为多个离散时间点的静态配送路线问题,构建以配送时间最短为目标的多应急配送中心、多应急需求点的配送路径优化数学模型。采用扫描算法将应急需求点分配给各配送中心,考虑到动态决策的快速决策要求,采用简便可行的节约算法进行求解。最后,结合昭通市情况,建立应急物资配送网络,将模型与算法运用到实例中去,对昭通市地震应急物资配送路线进行研究,为昭通市应急救援决策提供一定的支持,促进该地区的应急物流体系的完善。
[Abstract]:Earthquake disaster is the most serious geological disaster of all natural disasters to human society. Earthquake disaster emergency rescue is a complex system engineering, in which the distribution of emergency relief materials is an important part of the rescue work. Efficient distribution will help to ensure the safety of people's lives and greatly reduce the serious losses caused by the earthquake. Therefore, it is necessary to study the distribution route of emergency materials for earthquake disaster. Based on the research background of Zhaotong earthquake emergency logistics, this paper firstly analyzes the situation of the city, the history of earthquake disaster and the present situation of earthquake emergency logistics, and finds out the problems existing in the distribution of emergency materials for earthquake disaster in Zhaotong city. Then, the earthquake emergency distribution route model and algorithm are studied to provide a method for solving the problem. Based on the characteristics of seismic emergency distribution, such as timeliness, weak economy and dynamic, this paper introduces the key nodes to transform the dynamic emergency distribution route problem into the static distribution route problem of multiple discrete time points. The mathematical model of distribution path optimization for multi-emergency distribution center and multi-emergency demand point is constructed. The scanning algorithm is used to assign the emergency demand points to the distribution centers. Considering the rapid decision requirements of dynamic decision making, a simple and feasible saving algorithm is used to solve the problem. Finally, according to the situation of Zhaotong City, the emergency material distribution network is established, and the model and algorithm are applied to the example to study the distribution route of the earthquake emergency materials in Zhaotong City, which provides some support for the emergency rescue decision of Zhaotong City. Promote the improvement of emergency logistics system in this area.
