I have taken impotance to analyze the rallying point of famous product , concrete cost and capability of providing and guarantee in this artical , meanwhile , i have caculated the quantity of concrete needed for the year and got the regression equation with the historic data for drilling footage of eight years and the consuming quantity of oilwell cement by the method of linear regression , and it has very significance for the making of stock contract and the plan of concrete production , i have analyzed the physical distribution of oilwell cement by the transpotation flex and the advantage or disadvantage between direct distribution and distribution to store in this artical , and i have tried to find the balance point of the two distribution ways by the ecnomic analysis and pointd out the conception of economic semidiameter , and come to the conclusion of direct distribution , distribution to store , and subarea of distribution to store at last 本文对油井水泥供应商在品牌号召力、水泥成本、供应保障能力等方面进行了详尽分析,并对供应商进行了能力排序;用线性回归方法从八年钻井进尺与油井水泥消耗量的历史数据推算了当年度油井水泥需求量,得出了回归方程,这对于油井水泥采购合同的制订、水泥供应商生产计划的制订具有相当重要的意义;从运输弹性分析出发对油井水泥物流配送进行了研究,对直达配送、入库配送的优缺点进行了详细的分析,在经济分析的基础上力求找到两种配送方式的均衡点,并提出了经济半径的概念,得出了直达配送、入库配送、入库分区距离等几项结论。
