摘要
文中根据铁路物流中心的特点和发展方向,基于铁路物流中心提供的时空资源与货物需要的时空资源保持平衡的原理分析了影响时空资源的相关因素及确定模型中相关参数的方法,改进了时空消耗模型。结合时空消耗法和供需平衡理论的建模方法与优点,综合考虑各种客观及主观因素,进一步优化其数学模型以更准确的确定铁路物流中心的规模,最终实现增强模型与铁路实际情况的匹配度的目的。
According to the characteristics and the development trend of the railway logistics center (RLC),this paper improves the space-time dissipative model (STDM)and analyzes the related elements that influence the space-time resources and the method for confirming the related parameters in the STDM,based on the principle of the balance between the space-time resources supplied by the RLC and by the freight.Combined with the modeling method of the STDM and the advantages of the theory of the balance between supply and demand,the mathematical model of the STDM is further optimized,considering sorts of objective and subjective factors,for the purpose of determining the scale of the RLC more precisely and eventually enhancing the matching rate between the STDM and the reality of the railway.
