摘要
粮食物流涉及许多因素,关键是物流的流向、流量、动力、流速等参量。依据这些基本的要素可以构造主要的物流变量,如粮食产消差量、粮食品种结构调剂量、特殊物流量和冗余物流量等。在理想的情况下,上述4个量之和可以表明总的粮食物流量。据此完成粮食物流预测模型的构造,可以达到简化的预测目的,为物流规划和物流管理提供便捷工具。
The grain logistics involves many complex factors,the key factors are flow direction,quantity of flow,flow power,flow velocity and other parameters.Based on these basic elements,major logistics variables can be constructed such as food production and consumption,quantity adjusting of food strains,exchange volume of grain,special logistics capacity and redundancy logistics capacity.In an ideal situation,the amount of the sum of these four may indicate the total amount of grain logistics.Accordingly,a forecast of the construction of grain logistics models can be completed to achieve the purpose of simplifying the forecast for the logistics planning and logistics management with a convenient tool.
