本科论文结论.232致谢…33参考文献34AbstractNow people have very high requirements for the operation speed of the logistics industry,RDC warehouse is a very important part of the logistics process,and efficient operation ofRDC warehouse can ensure the timeliness of logistics.However,the existing RDC warehousegenerally remains unchanged after the warehouse is built.The operation efficiency of thewarehouse will decrease with the change of demand.When the demand changes,it will stilloperate in the old operation mode,which will result in unreasonable resource allocation,lowequipment utilization and high storage cost.The purpose of this design is to optimize theefficiency of the existing RDC warehouse and restore or even exceed the original level.Usingthe simulation software Flexsim,we can simulate the warehousing operation process ofe-commerce logistics through simulation,and study the results of the existing system andmodel operation,which will improve the warehousing both in terms of links and layout.This design first introduces the theory of e-commerce logistics and Flexsim technology,thenbased on the current situation,it analyzes the efficiency of RDC warehouse in and out,picking process and recheck packaging efficiency and other links,and analyzes the problemsin each link,mainly including low efficiency of in and out,unreasonable layout in thewarehouse,obsolete equipment,low packaging efficiency.Based on the theory of Flexsimsimulation software,Use Flexsim software to build simulation mode.After the system andspecific simulation objectives are determined,the model is simplified and assumedobjectively and reasonably.According to the different behavior characteristics of each entity,the parameters of the entity in the model are set and the simulation model is run.Through theanalysis of the output results of the simulation model,find out the problem and give a specificoptimization scheme,focusing on the in and out operation,the layout in the library andpackaging efficiency,and verify the rationality of the scheme.The conclusion is that theefficiency of in and out of warehouse is improved,the layout of warehouse is more reasonable,and the packaging efficiency is obviously improved.The research of this paper accords with the actual development demand of RDC warehouse ina logistics center in East Asia,Beijing.It provides a certain reference value for the reductionof the cost of logistics storage industry,the utilization rate of equipment,and the improvementof storage operation efficiency,and also take effect in promoting the rapid development oflogistics industry.
