时空消耗法求解物流园区规模

Calculating the Size of a Distribution Park by the Space-time Consumption Method

运用时空消耗的理论建立了物流园区规模预测模型。模型是基于物流园区提供的时空资源与货物需要的时空资源保持平衡的原理建立,同时分析了影响时空资源的因素及其在模型中相关参数的确定,最后以北京城市物流系统规划为例具体说明了本模型的应用。

This paper describes a mathematical model developed for detemfining the optimal size of a distribution park.Space-time consumption theory was used to determine the best solution. The model takes into account the space and time of freight, and other factors, such as time variation. All the variations were analyzed.As an example, it was applied to calculate the sizes of all the distribution parks in Beijing, China.
