【摘要】：对于制造企业而言,仓储物流是企业物流中至关重要的内容。对仓储系统进行优化,可以有效地提高企业整体物流效率。日化用品行业的订单具有着多品种、小批量的特点,其仓储出入库的效率对整体物流与供应链效率会产生着直接的影响。本文的研究对象为B日化用品制造企业的仓储出入库系统,为解决出库备货区存在的堆积问题,提出一种依装车顺序取货的仓储出入库系统方案。这种方案是从改善出库备货区货物放置规则和改进货物装车流程两个角度出发,以期达到提高仓储出入库系统效率的优化目的。首先,本文对B日化用品制造企业的现状进行分析,在日化用品行业现状分析和B公司物流现状、供应链现状分析的基础上,指出B公司仓储出入库系统现存问题,即出库备货区环节的堆积问题。为解决这一问题,提出依装车顺序取货的仓储出入库系统优化方案。然后,根据B公司的仓储出入库业务流程,利用Petri网对仓储出入库流程进行作业流程梳理,为下文仿真建模提供依据。其次,应用三维仿真软件,对B日化用品制造企业的四种产品的仓储出入库系统情况进行仿真建模。利用LoadMaster装箱大师软件对货物装车问题进行仿真,得出最大化装车率下的最优装车方案。在此基础上,利用Flexsim软件对优化前后的仓储出入库系统进行仿真。在其他条件不变的情况下,将原先装车人员按装车顺序取货的方案优化为仓储出入库系统直接按照装车顺序从立库中进行取货的方案,并对原仓储出入库系统的出库输送线、出库备货区、装车人员进行资源整合。最后,对利用Flexsim仿真建模优化前后的仿真运行结果进行分析,对比优化前后的设备及人员的状态比率。根据仿真对比结果,优化后的仓储出入库系统整体运行时间缩短,出库备货区堆积现象得到缓解,出库传送带利用率提高,人员得以精简,仓储出入库效率提高。
[Abstract]:For manufacturing enterprises, warehousing logistics is an important part of enterprise logistics.Optimization of warehousing system can effectively improve the overall logistics efficiency of enterprises.The order of daily chemical products industry has the characteristics of many varieties and small quantities. The efficiency of storage and storage has a direct impact on the efficiency of the whole logistics and supply chain.The research object of this paper is the storage and entry and storage system of B daily chemical products manufacturing enterprise. In order to solve the problem of stacking in the storage and storage area, this paper puts forward a kind of storage and entry and storage system scheme which takes goods in the order of loading.This scheme is based on the two aspects of improving the rules of goods placement and the loading flow of goods in the storage and storage area in order to improve the efficiency of the warehousing and warehousing system.First of all, this paper analyzes the current situation of B daily chemical products manufacturing enterprises, on the basis of the analysis of the current situation of daily chemical products industry, B company logistics status, supply chain status analysis, points out the existing problems of B company warehousing and storage system.That is, the storage and storage area of the accumulation of links.In order to solve this problem, the optimization scheme of warehousing and warehousing system is put forward.Then, according to the business process of B company, we use Petri net to sort out the process of warehouse entry and exit, which provides the basis for the simulation modeling below.Secondly, three dimensional simulation software is used to simulate the storage and storage system of four kinds of products in B daily chemical products manufacturing enterprise.The LoadMaster loading master software is used to simulate the cargo loading problem, and the optimal loading scheme under the maximum loading rate is obtained.On this basis, the Flexsim software is used to simulate the storage system before and after optimization.When other conditions are unchanged, the original scheme of loading personnel to pick up goods in the order of loading is optimized as the scheme of the warehousing, outgoing and warehousing system to carry out the goods directly from the vertical warehouse in accordance with the loading order, and for the delivery line of the original warehousing and outgoing storage system,Loading area, loading personnel to carry out the integration of resources.Finally, the simulation results before and after optimization using Flexsim simulation modeling are analyzed, and the state ratio of equipment and personnel before and after optimization is compared.According to the results of simulation, the whole running time of the system is shortened, the stacking phenomenon in the storage and storage area is alleviated, the utilization ratio of the outgoing conveyor belt is improved, the personnel is streamlined, and the efficiency of the storage and incoming storage is improved.
