LINGO语言与0-1混合整数规划选址模型的再结合

Lingo Language in the Logistics Distribution Center Location

目前现有的将LINGO语言和O-1整数规划模型结合解决物流配送中心选址的理论较多,但不完善,主要表现在建模时对费用的考虑不全面、编程时所使用的变量不统一和求解时使用的是算例,数据真实性不高。针对以上问题,论文对LINGO语言与0-1混合整数规划选址模型进行再结合。首先把与配送相关的物流活动分为进货、仓储和送货三大物流环节,由此将配送中心选址中所涉及到的费用分为进货运输费用、仓储费用和送货配送费用;其次对建模所涉及到变量进行科学的规范,并成功建立O-1整数规划模型;最后以邯郸交通运输集团物流配送中心选址为实例,运用所建立的0-1混合整数规划模型,编写相应的LINGO求解程序,通过运行得出邯运集团在石家庄、北京、邯郸建立配送中心此时费用最少,最终到达LINGO语言与0-1混合整数规划选址模型的完美结合。

Currently available to LINGO language and 0-1 integer progranuning model to solve logistics distribution cen- ter location with the theory of more, but not perfect, Mainly manifested in the modeling of the cost considerations are not compre- hensive, the variables used in programming and solving non-uniform use of the example, the data authenticity is not high. To solve the above problems, this paper on the LINGO language and 0-1 mixed integer programming model for re-location combi- nation. First of all the logistics and distribution-related activities into purchasing, warehousing and delivery logistics links the three, thus the distribution center location to the costs involved in transport costs into purchasing, warehousing, distribution costs and delivery costs; Secondly, modeling of the variables involved in a scientific norms and the successful establishment of 0-1 in- teger programming model; The end, the Group Handan transportation logistics and distribution center location as an example, us- ing established by 0-1 mixed integer programming model, write the corresponding LINGO solver, obtained by running the Han Wan Group in Shijiazhuang, Beijing and Handan to establish distribution centers in this When the least expensive and ultimately reach the LINGO language and 0-1 mixed integer programming model was the perfect combination of location.
