供应链网络设计问题中的物流需求研究

A Research on Logistics Demand in Supply Chain Network Design

对供应链网络设计问题中涉及的物流需求进行合理的梳理、分析和描述,是供应链网络设计模型的基础,可以帮助供应链网络设计模型的建立和优化。对物流空间需求和时间需求进行分析,针对现有空间需求的误差和局限性,提出基于地理信息处理工具描述的区域面随机需求和节点集聚需求,利用期望值函数描述不确定性物流需求,并构建表述时间需求的需求点不被覆盖函数,指出各种需求描述在供应链网络设计问题中的应用方向。

Classification, analysis and representation of logistics demand, involved in supply chain network design, is the basis of supply chain network design formulation. It could be conducive to the establishment and optimization of supply chain network design model. This paper analyzes the logistics space demand and time demand. With reference to the existing errors and limitations of space demand, this paper proposes the area random demand and node cluster demand based on geographic information processing tools, describing the uncertainty logistics demand by the expected demand function, and formulates the demand uncovering function to represent the time demand. The application direction of demand representation in supply chain network design is given in the conclusion.
