【摘要】：伴随着我国经济的迅速增长,物流业的发展也进入了空前鼎盛的阶段。近年来,各大生产制造企业以及物流企业更是建起了自己的物流配送中心,以确保原料及商品流通过程中降低成本、提高库存周转率以及物流系统的运作效率,最终达到提升企业经济效益和服务水平的目标。但现实是物流配送过程的规划在我国起步较晚,其中最主要的原因是建设配送中心的费用较高,设计与规划配送过程的相关理论还不够成熟和完善,因此投资建设配送中心对于企业来说存在很大的风险。鉴于上述现实背景,为了物流配送过程的设计与规划更加具有合理性和科学性是本文研究的根本意义所在。另外,系统仿真技术是贯穿于本文研究的一个重要方法,它是将计算机仿真技术应用在了配送过程的设计规划中,利用Flexsim仿真软件可以有效地验证规划方案的可行性及其实施效果,从而帮助企业避免设计与规划中的诸多风险。本文主要引入了物流配送过程中的几个实际问题,通过相关的理论学习及方法的应用,最终将其实施在物流配送问题中,并通过系统仿真的方法验证解决方案的可行性和合理性。首先,本文提出了为某多功能医药配送中心实施布局规划的问题,针对其作业流程及功能区域划分的设计结果,运用SLP法确定了该配送中心的布局规划方案,之后通过对布局规划方案的仿真分析,验证了该方案基本满足配送中心内的物流顺畅以及企业的作业需求。其次,又提出了某电商企业配送中心内分拣策略的选择问题,基于合理的订单分批方法可以大大提高分拣作业效率以及减少搬运行走距离的理论,以一般订单分批策略作为基础,为该企业制定了两种优化的订单分批策略,之后,结合仿真分析方法为该配送中心分拣系统选择出了最优的订单分批策略。最后,本文针对某汽车零件生产企业提出了生产配送方式的优化问题,在探讨了两种典型生产模式下的物料配送系统存在的不足后,提出了一种优化的生产配送方式,之后,基于Flexsim仿真软件验证了该优化方式可以为企业有效的降低库存水平和提高生产效率。本文通过三个实际问题的分析过程,阐述了物流配送系统对于提高企业效率、降低物流及生产成本的重要性,以及系统仿真方法解决物流配送问题的现实意义。
[Abstract]:With the rapid economic growth in China, the development of logistics industry has entered an unprecedented stage. In recent years, the major manufacturing enterprises and logistics enterprises have built their own logistics distribution center to ensure the reduction of costs in the process of raw materials and commodity circulation, improve inventory turnover and the operational efficiency of the logistics system. Finally, to achieve the goal of improving the economic efficiency and service level of enterprises. However, the reality is that the planning of logistics distribution process starts late in our country, and the main reason is that the cost of constructing distribution center is high, and the relevant theories of designing and planning distribution process are not mature and perfect enough. Therefore, investment in the construction of distribution centers for enterprises there is a great risk. In view of the above realistic background, it is the fundamental significance of this paper to design and plan the logistics distribution process more reasonably and scientifically. In addition, the system simulation technology is an important method that runs through the research in this paper. It applies the computer simulation technology to the design and planning of the distribution process. Flexsim simulation software can effectively verify the feasibility of the planning scheme and its implementation effect, thus helping enterprises to avoid many risks in the design and planning. This paper mainly introduces several practical problems in the process of logistics distribution, through the relevant theoretical study and the application of methods, it is finally implemented in the logistics distribution problem. The feasibility and rationality of the solution are verified by system simulation. First of all, this paper puts forward the problem of implementing layout planning for a multi-functional medical distribution center. According to the design results of its work flow and functional area division, the layout planning scheme of the distribution center is determined by using SLP method. Through the simulation and analysis of the layout planning scheme, it is verified that the scheme basically meets the smooth logistics in the distribution center and the operational requirements of the enterprise. Secondly, the selection of sorting strategy in the distribution center of an e-commerce enterprise is put forward. Based on the theory that reasonable order batch method can greatly improve the efficiency of sorting operation and reduce the distance between transportation and walking, Based on the general order batch strategy, two optimized order batching strategies are developed for the enterprise. After that, the optimal order batch strategy is selected for the distribution center sorting system with the simulation analysis method. Finally, this paper puts forward the optimization of production and distribution mode for a certain automobile parts manufacturing enterprise. After discussing the shortcomings of the material distribution system under two typical production modes, this paper puts forward an optimized production and distribution mode. The simulation software based on Flexsim verifies that the optimization method can effectively reduce the inventory level and improve the production efficiency. Through the analysis of three practical problems, this paper expounds the importance of logistics distribution system in improving enterprise efficiency and reducing logistics and production cost, as well as the practical significance of system simulation in solving logistics distribution problems.
