【摘要】：近几年，各类突发事件越趋频繁，给国家带来了重大损失，给人民生命带来了巨大的威胁，应急管理工作正受到国家和人民的重视，从而应急管理问题的研究也就成为了既棘手又具有挑战性的一项重要课题。医药物资作为挽救生命的关键性应急资源，能否在应急过程中得到有效保障是应急管理工作成败的重要因素之一，在应急管理中起着不可替代的作用。但实际救援中，医药物资的供应与配送仍存在不合理、混乱和调度瓶颈等不良现象，严重影响了应急效率，阻碍了医疗救助工作的顺利进行。因此，本文认为，研究如何合理分配医药物资、改善医药物资在应急调度中的低效率问题，对促进医药物资应急调度工作的科学化发展，具有重要的现实意义。本文以医药物资在应急过程中的调度问题为对象进行了研究，其内容主要包含三部分：第一，在对突发事件、应急调度和优化算法三方面理论文献综述的基础上，总结了应急过程中所需医药物资的应急特性，从宏观角度分析了我国医药物资的应急保障现状，提出了我国医药物资保障体系的发展方略，并结合实际救援中医药物资供应与需求特点，提出了医药物资的应急调度特征；第二，在已研究的理论基础上，分析了医药物资应急调度的理想方案是最小化调度时间的前提下，达到各灾区点医药物资未满足需求量最少，从而构建了应急调度时间最小化和未满足需求量最小化的双目标调度优化模型，并根据实际情况将问题界定为多配送点多需求点的调度拓扑体系研究；第三，借鉴传统遗传算法，，设计了适合本文模型的改进遗传算法，并使用MATLAB R2011对其予以实现，利用简单算例进行了仿真验证。结果显示，本文改进遗传算法求解效果良好，能有效解决所建模型的调度问题，并验证了本文调度模型具有可行性。
[Abstract]:In recent years, all kinds of emergencies have become more and more frequent, which has brought great losses to the country and a great threat to the lives of the people. The emergency management work is being taken seriously by the state and the people. Therefore, the study of emergency management has become a difficult and challenging important issue. Medical supplies as the key emergency resources to save lives. Whether can get the effective safeguard in the emergency process is one of the important factors of the success or failure of the emergency management, and plays an irreplaceable role in the emergency management, but in the actual rescue. The supply and distribution of medical materials are still unreasonable chaos and scheduling bottlenecks and other adverse phenomena seriously affect the efficiency of emergency and hinder the smooth progress of medical relief work. It is of great practical significance to study how to distribute medical materials reasonably and improve the low efficiency of medical materials in emergency dispatch. It is of great practical significance to promote the scientific development of medical materials emergency dispatch. In this paper, the scheduling of medical supplies in the emergency process as an object of study, its content mainly includes three parts: first, in the emergency. Based on the literature review of emergency dispatch and optimization algorithm, this paper summarizes the emergency characteristics of medical materials needed in the emergency process, and analyzes the current situation of emergency support of medical materials in China from the macro point of view. The development strategy of medical material security system in China is put forward, and the characteristics of emergency dispatch of medical materials are put forward according to the characteristics of supply and demand of actual relief Chinese medicine materials. Secondly, on the basis of the theory that has been studied, the paper analyzes the ideal plan of medical material emergency dispatch is to minimize the scheduling time, and reach the least demand of medical materials in various disaster areas. Thus, a two-objective scheduling optimization model of minimizing emergency scheduling time and minimizing unsatisfied demand is constructed, and the problem is defined as the scheduling topology system of multi-distribution points and multi-demand points according to the actual situation. Thirdly, using the traditional genetic algorithm for reference, an improved genetic algorithm suitable for the model of this paper is designed and implemented with MATLAB R2011, and a simple example is used to verify the simulation. The result shows that the improved genetic algorithm is suitable for the model of this paper. The improved genetic algorithm is effective in solving the scheduling problem of the established model, and the feasibility of the proposed model is verified.
