基于状态空间法的物流枢纽承载能力模型可以有效评估物流枢纽的承载状态。根据承载体构成维度的不同,采用逐层剥离的方法,根据系统状态点与原点的矢量模对物流枢纽承载能力进行数学表达,利用实际物流枢纽承载状态矢量与理想承载能力矢量之间的夹角描述物流枢纽承载状态,分别构建物流枢纽综合承载能力模型、物流枢纽系统承载能力模型和物流枢纽基础设施承载能力模型,根据模型能够对物流枢纽的可载、满载和超载状态进行判定。
基于狀態空間法的物流樞紐承載能力模型可以有效評估物流樞紐的承載狀態。根據承載體構成維度的不同,採用逐層剝離的方法,根據繫統狀態點與原點的矢量模對物流樞紐承載能力進行數學錶達,利用實際物流樞紐承載狀態矢量與理想承載能力矢量之間的夾角描述物流樞紐承載狀態,分彆構建物流樞紐綜閤承載能力模型、物流樞紐繫統承載能力模型和物流樞紐基礎設施承載能力模型,根據模型能夠對物流樞紐的可載、滿載和超載狀態進行判定。

In order to assess the carrying status of logistics hub effectively, the authors put forward the model of logistics hub carrying capacity based on state-space method. The authors also build the structure model based on the analysis of the concept of logistics hub carrying capacity. Besides, the authors construct the comprehensive carrying capacity model, system carrying capacity model and infrastructure carrying capacity model of logistics hub respectively with the method of stripping step by step, according to the different constitutes dimensions of carrier. In the end, the authors build a mathematical expression of logistics hub carrying capacity according to the vector norm of system state point and the origin, and describe the carrying status of logistics hub using the angle between the vectors of the actual state and the ideal state of logistics hub. Furthermore, the author put forward the corresponding countermeasures respectively according to the load, full load and overload condition of logistics hub carrying capacity by the model.
