本科论文摘 要我国是一个产粮大国,2019 年全国粮食总产量超过 8.6 亿吨。但是同时又是人口基数很大的国家,国内每人平均粮食含有量仅能维持正常的生活。众所周知,粮食是一个国家的战略物质,所以说粮食问题尤为重要。目前 M 市的粮食物流中心处在设计过程中,但粮食产品运转的目的性较弱,粮食产品的最终利润不高。合理的选址和设计 M 市粮食物流中心是目前国家和相关企业急需解决的问题。本设计主要根据目前 M 市的粮食物流行业的发展近况,分析我国粮食物流中心存在的一系列问题,制定了重心法与层次分析法相互联系的综合性质的选址方法。重心法是最常见的选址方法,通常能够简单的得到初选的地址。但其选址得到的初始位置往往在实践中难以实现,因为迭代得出来的初始地点在现实中有极大的可能不符合实际,所以只好在初始选址的近处寻找到适合该特点的备选方案,因此再利用层次分析法从备选位置中确定最优位置,最后用模糊综合评价法进行专家打分。这三种方法在国内如今的粮食物流中心选址流程中具有一般可操作性,基本能够为我国相似地方的粮食物流中心选址问题提供有力的导向性作用。关键词:粮食物流;物流中心选址;重心法;层次分析法;VBA-Excel本科论文AbstractChina is a large grain producer, with a total grain output of more than 860 million tons in 2019. But at the same time, it is a country with a large population base. The average food content per capita in China can only maintain a normal life. As we all know, food is a country's strategic material, so the food problem is particularly important. At present, the grain logistics center of M city is in the process of design, but the purpose of grain product operation is weak, and the final profit of grain product is not high. Reasonable location and design of M City Grain Logistics Center is an urgent problem for the country and related enterprises.According to the current development of grain logistics industry in M City, this design analyzes a series of problems existing in China's grain logistics center, and formulates a comprehensive...
