以物流供需匹配度为目标的流线优化模型

Stream Line Optimization Model with Matching Degree between Logistics Supply and Demand as Objective Function

为揭示典型物流活动的一般规律与特征,在分析物流供需关系的基础上,构建了具有多层、多级、多属性特征的流线网络结构和数学描述,并讨论了制造、贸易和区域物流活动的3种退化情形.定义了匹配度,以描述物流服务与物流需求在时间、数量、费用等因素方面的匹配关系.建立了以物流供需匹配度最大化为目标函数,以能力和资源限制为约束条件的流线优化模型.

To reveal the basic laws and characteristics of logistics activities,a stream line network structure with multi-layer,multi-stage,and multi-attribute was proposed based on the relationship between logistics supply and demand,and the mathematical description was presented.Three kinds of degradation structures of industrial,trading and regional logistics activities were discussed.The matching degree was defined to describe the relationship between logistics supply and demand in terms of time,quantity and cost.A stream line optimization model was set up,in which the matching degree between supply and demand was taken as the objective function and the capacities and resources as the constraints.
