【摘要】：每一场突发事件都会遇到应急物资的配送问题,应急物资是否能够准确且高效地被运送至应急物资需求点是开展救援工作的关键。要提高整个应急物流系统的配送效率,不仅要选择合理的配送路径,还应该从应急物资配送的前端开始研究,进行合理的、科学的规划,使所需的应急物资尽量快速高效的到达应急物资需求点,提高整个应急物流系统的救援效率。本文所做的工作主要体现在以下几个方面：文章首先结合国内外研究现状分析了学术界在应急物资分类和应急车辆配送路径方面的研究成果,在前人研究的基础上提出了本文的研究内容,即基于应急物资分类.分批配送的应急车辆路径研究。并且介绍了文章用到的相关理论知识。接着文章对应急物资分类.分批配送模式做了阐述,并对应急物资的分类进行了研究,提出了基于事件.需求及时性和采购困难度两个分类指标的应急物资分类,将应急物资分为第一批配送的Ⅰ类和第二批配送的Ⅱ类两类物资。然后针对配送批次不同的两类应急物资分别建立了相应的应急车辆路径模型,第一批配送的Ⅰ类应急物资考虑应急物流系统时间和驾驶员个人行为因素的VRP模型和第二批配送的Ⅱ类应急物资考虑应急物流系统时间和成本的VRP模型。最后以雅安地震为背景设计一个算例来验证前两章研究内容的合理性。在文章的结尾对全文做了一个小节,指出了本文研究的不足之处,并对进一步的研究做了展望。
[Abstract]:Every emergency will encounter the problem of emergency material distribution. Whether the emergency material can be delivered to the emergency material demand point accurately and efficiently is the key to carry out the rescue work. In order to improve the distribution efficiency of the whole emergency logistics system, we should not only choose a reasonable distribution path, but also start the research from the front end of the emergency material distribution, and carry out reasonable and scientific planning. The emergency materials can reach the emergency material demand point quickly and efficiently, and improve the rescue efficiency of the whole emergency logistics system. The work done in this paper is mainly reflected in the following aspects: Firstly, this paper analyzes the research results of emergency material classification and emergency vehicle distribution route in the academic field, and puts forward the research content of this paper based on the former research, that is, emergency material classification. Research on Emergency vehicle routing in batch Distribution. And introduced the relevant theoretical knowledge used in the article. Then the article classifies the emergency materials. The mode of batch distribution is expounded, the classification of emergency materials is studied, and an event-based approach is proposed. According to the classification of emergency materials, the emergency materials can be divided into two categories: the first group and the second group. Then the corresponding emergency vehicle routing model is established for the two types of emergency materials with different distribution batches. The VRP model for the first batch of emergency materials and the VRP model for the second batch considering the time and cost of the emergency logistics system. Finally, an example is designed to verify the rationality of the previous two chapters. At the end of this paper, a section is made to point out the inadequacies of this paper, and the further research is prospected.
