摘要
基于山东省的地理特点,在若干假设前提下研究从供应商到制造厂,再从制造厂到物流中心的三点二层的线性规划问题的最优解。由于涉及节点较多,不方便运用运筹学上的单纯形法和表上作业法,而用到一种专门求解优化模型的软件即LINGO软件。经过若干组数据的比较和规律总结,得出山东省基于三点两层物流问题的最优路径,并确定所选路径上的运输量以及最低的物流成本。
In view of the geographical characteristics of the Shandong province,the paper studies the optimal solution to the linear programming problem of a hypothetical logistics network consisting of three nodes,i.e.the supplier,manufacturer,and logistics center,and two layers,i.e.the supplier to the manufacturer,and the manufacturer to the logistics center.The paper chooses Lingo,a specialized optimization model solution software,over the simplex method and the table dispatching method due to the rather large number of nodes involved.After a certain amount of data comparison and pattern summarization,the paper obtains the optimal route for the hypothetical logistics network of Shandong and determines the transport volume for the route as well as the minimum logistics cost.
