供需量不确定下多供应地到多需求地的运输成本模型研究

The Model of Transportation Cost From Multiple Supply Locations to Multiple Demand Locations with Uncertain Supply and Demand

物流成本是物流企业赖以生存发展的关键所在,其中运输成本在物流成本中占比较大。如何保证在不缺货的情况下充分利用企业的运输能力,使得企业物流收益最大化、运输成本最低是我国物流行业当前亟待解决的的问题。以S公司为研究对象,以物流运输成本的构成项目和影响因素为切入点建立供需变化下物流运输成本优化模型。该模型主要是解决多个供应地到多个需求地、且供需量不确定下的最佳运输方案问题。将求解结果与之前的运输成本相比较,比较结果表明运输成本明显降低了,证明该模型可以对S公司运输成本起到优化作用。

Logistics cost is the key to the survival and development of logistics enterprises,among which transportation cost accounts for a large proportion.How to make full use of the transportation capacity of a logistics enterprise without shortage of goods,to maximize the profit and to minimize the transportation cost is an urgent problem to be solved for China's logistics industry.Taking company S as the research object,and taking the components of logistics transportation cost and factors influencing the cost as the starting point,the paper establishes the logistics transportation cost optimization model under the change of supply and demand.This model is mainly used to provide the best transportation scheme when there are many supply places to many demand places and when the supply and demand are uncertain.Compared with the previous transportation cost,the result shows that the transportation cost is significantly reduced,which proves that the model can optimize the transportation cost of company S.
