供应链物流能力:流通量和响应时间测算模型

对供应链整体物流过程中的能力表现进行了建模、量化与测度．针对大部分的物流能力多以“数量”和“时间”为基础这一事实，将供应链网络视作完整的物品流通平衡网络，对供应链的最大流量、整体流通量和响应时间三个指标进行了分析和推导，确定了指标测度的量化公式．通过对公式的分析，从节点的流通能力和处理时间、节点之间路线上物品的流量、节点之间路线的长度、路线上物品移动的速度和路线上花费的时间等五个方面，对提高供应链流通和时间响应能力进行了简要分析．

Calculating model for the circulation and response time in supply chains

The model for describing general logistics ability in supply chains was build and measured.It is the basic fact that most logistics capability is based on the quantity and time. Thus, supply chain networks are regarded as an intact equilibrium model of physical distribution. Three logistics capability indexes, maximal flow capacity, whole circulation and response time, were derived, and their mathematic formulae are given. How to improve the calculation and response time in supply chains were studied from five aspects, including the circulation ability and distribution time on the nodes, the route circulation and length among supply chain nodes, the physical floating speed in supply chain routes and the spent time on the routes.
