【摘要】：近年来自然灾害频发,灾害会造成大量的难民、灾民。灾区粮食供应的快速有效,是粮食应急物流需要考虑的首要问题。首先面临的一个问题就是粮食的应急供应和粮食的紧急调运、配送。这是在灾害发生后,紧急拉动粮食的需求。而粮食应急物流不仅仅要考虑事后的应急响应,还需要考虑灾害发生前粮食应急物流网点的建设,粮食应急加工网点的布局,粮食应急配送网络的筹划,以及与仓储、加工、配送、装卸搬运、包装等相联系的基础设施的建设,应急组织的确立,粮食应急物流信息系统的建设等相关方面。目前粮食应急物流系统的研究已经成为中国现在热门研究的话题。本文主要是对粮食应急物流系统进行研究。首先论述了本文的研究背景和意义,并对国内外学者关于此话题的相关文献进行了回顾和研究总结;其次在阐述相关概念的基础上,试图建立一个符合实际情况的粮食应急物流系统,并在这个系统的基础上适当简化,主要是从粮食储备、粮食应急加工、粮食应急运输与配送三个主要模块进行分析研究,利用Flexsim仿真软件对这个简化的系统进行建模。尽可能构建一个贴近事实的地震情景下粮食应急物流系统的模型,对这个情景进行Flexsim仿真。通过仿真找出系统存在的问题,并对这个系统进行优化。由于国内关于应用Flexsim仿真软件来进行粮食应急物流系统研究的不多,本文可以为以后的研究者提供一定的参考。而且建模仿真的成本往往比真实构建这个系统后又发现具有不合理的地方,然后进行重建的成本低,所以通过仿真可以为决策者提供一些理论参考。
[Abstract]:In recent years, frequent natural disasters, disasters will cause a large number of refugees, victims.The fast and effective food supply in the disaster area is the most important problem that should be considered in the food emergency logistics.The first problem is the emergency supply of grain and the emergency dispatch and distribution of grain.This is the emergency in the aftermath of the disaster, the demand for food.Food emergency logistics should not only consider the emergency response afterwards, but also consider the construction of grain emergency logistics network before disasters, the layout of grain emergency processing network, the planning of food emergency distribution network, and storage and processing.Distribution, handling, packaging and other related infrastructure construction, emergency organization establishment, food emergency logistics information system construction and other related aspects.At present, the research of food emergency logistics system has become a hot topic in China.This paper mainly studies the grain emergency logistics system.Firstly, it discusses the research background and significance of this paper, and reviews and summarizes the relevant literature of domestic and foreign scholars on this topic; secondly, on the basis of expounding the relevant concepts,This paper attempts to establish a grain emergency logistics system in line with the actual situation, and on the basis of this system, appropriately simplifies it, mainly from the three main modules of grain storage, food emergency processing, food emergency transportation and distribution.The simplified system is modeled by Flexsim simulation software.As far as possible, a model of grain emergency logistics system under the earthquake scenario is constructed, and the Flexsim simulation of this scenario is carried out.The problems of the system are found out by simulation, and the system is optimized.Due to the lack of domestic research on the application of Flexsim simulation software to the grain emergency logistics system, this paper can provide a certain reference for future researchers.Moreover, the cost of modeling and simulation is often lower than that of the real system, and then the cost of reconstruction is lower, so the simulation can provide some theoretical reference for decision makers.
