【摘要】：近年来,随着移动互联网的发展,移动终端的销量正在逐年提升因此全球运营商的营业厅在已有的传统业务基础上,逐渐淡化传统服务模式,将营业厅的营销重心由服务转向了终端的销售。但在转型的过程中,运营商营业厅遭遇了热销终端缺货、终端配送调度不周全、终端配送过慢等问题,主要原因都在于配送的不及时及配送系统的紊乱。因此配送中心选址是否科学合理则显得尤其重要。针对现状及存在问题,论文采用Baumol-Wolfe模型及Witness仿真相结合的方法对某运营商的选址问题进行了布局设计和研究,为其选址提出了最优的解决方案。首先,论文结合研究背景对配送中心选址的国内外研究现状进行归纳总结,通过汲取优秀经验发现问题提炼论文的研究角度及方法。其次,论文在优化的最大覆盖原则基础上构建基于运营商物流配送总成本的Baumol-Wolfe模型,通过各备选配送中心通货量的迭代运算不断逼近最小配送成本以求得最优解,实现配送中心的初步选址。再次,论文构建基于Witness仿真软件的运营商物流配送中体系仿真模型,通过仿真一段时间的终端配送工作,动态地显示各配送中心的配送成本数据。最后,论文基于Witness软件的optimizer优化模块对模型进行优化,通过配送中心通货概率及总成本两个指标对备选站点进行筛选,最终得出运营商选址最优方案。
[Abstract]:In recent years, with the development of mobile Internet, the sales volume of mobile terminals is increasing year by year. Therefore, on the basis of the existing traditional business, the business hall of global operators gradually desalinated the traditional service mode, and changed the marketing focus of the business hall from the service to the sales of the terminal. However, in the process of transformation, operators encountered hot terminal shortage, terminal distribution scheduling is not complete, terminal distribution is too slow and other problems, the main reasons are not timely distribution and the disorder of distribution system. Therefore, it is particularly important whether the location of distribution center is scientific and reasonable. In view of the present situation and existing problems, this paper adopts the method of Baumol-Wolfe model and Witness simulation to design and study the layout of the location problem of an operator, and puts forward the optimal solution for its location. First of all, combined with the research background, the paper summarizes the research status of distribution center location at home and abroad, and finds out the research angle and method of the paper by drawing on the excellent experience. Secondly, on the basis of the optimized maximum coverage principle, the Baumol-Wolfe model based on the total cost of logistics distribution of operators is constructed, and the optimal solution is obtained by approaching the minimum distribution cost through the iterative operation of the deflation of each alternative distribution center, and the preliminary location of the distribution center is realized. Thirdly, the system simulation model of operator logistics distribution based on Witness simulation software is constructed, and the distribution cost data of each distribution center is displayed dynamically by simulating the terminal distribution work for a period of time. Finally, based on the optimizer optimization module of Witness software, the model is optimized, and the alternative sites are screened through the two indexes of currency probability and total cost of the distribution center, and finally the optimal scheme of operator location is obtained.
