某超市结账柜台排队系统

I题目某超市结账柜台排队系统的仿真研究摘要近年来，形形色色的超市不断兴起给我们的生活带来了诸多便利。但由于许多原因，许多超市的结账柜台排队系统并不十分的完善，时常出现排队过长或结账柜台空闲等等问题，因此，优化超市结账柜台排队系统，缩短结账时间具有极大的意义。本文将针对永辉超市结账柜台排队系统进行优化。首先会介绍排队论及其相关知识，对多队列、多服务台等待制M/M/c/∞/∞排队模型进行了重点阐述。其次对永辉超市的顾客到达时间，顾客服务时间进行调研。在取得原始数据后，代入排队模型公式进行数据分析与参数计算，得出计算机仿真所需的参数与变量，同时确定永辉超市的最佳结账柜台的数量。然后运用FLEXSIM对结账柜台排队系统进行仿真以确定该优化方案是可行的。最后，本文给出了一些超市发展的建议。本文的研究结论可能对相类似的排队系统具有一定的借鉴意义。关键词超市结账柜台排队系统建模仿真IITitleSimulationandresearchonthecheckoutcounterqueuingsystemofsupermarketAbstractInrecentyears,thevarioussupermarketshavebroughtmanyconveniencestoourlife.Buttherearemanyreasonstoleadmanysupermarketcheckoutcountersqueuingsystemisnotveryperfect.Thelongqueueorsparecheckoutcountersandsoon.Therefore,theoptimizationofthesupermarketcheckoutcountersqueuingsystemcanhelpthesupermarkettoprofoundlyshortenthecheck-outtime.ThisthesisaimedattooptimizethecheckoutcounterqueuingsystemofYonghuisupermarket.Atfirst,theknowledgeaboutqueuingtheoryhasbeenintroduced,andtheMulti-queuemulti-serviceplatformforM/M/c/∞/∞queuingmodelhasfocusedon.Secondlyasurveyofcustomerarrivaltime,servicetimeandotherbasicdatahasconductedatYonghuisupermarket.Next，Intherawdata,byusingtheFLEXSIMservicesystemtoconductasimulation,findingouttheoptimizationisfeasible.Finally,thisthesishasgivesomeadvicesabouthowtodevelopmentthesupermarket.Theconclusionofthispapermayhavesomereferencesignificancetosimilarqueuingsystem.KeywordsSupermarketPartsinventorySimulationthecheckoutcounterqueuingsystemIII目录1．绪论...................................................................................................................................................11.1课题研究背景与意义............................................................................................................11.2国内外研究现状....................................................................................................................11.3论文的主要研究内容与组织结构......................................................................................31.3.1论文主要研究内容....................................................................................................31.3.2论文主要组织结构....................................................................................................42．论文相关概念与理论.....................................................................................................................52.1排队论......................................................................................................................................52.1.1排队论的概念与发展............................................................................................52.1.2排队论的主要研究内容...........................................................................................52.2排队系统.................................................................................................................................62.2.1排队系统的组成........................................................................................................62.2.2排队系统的主要指标..............................................................................................72.2.3排队系统的最优化................................................................................................82.3排队系统的建模.................................................................................................................92.3.1系统建模的要求....................................................................................................92.3.2系统建模的原则....................................................................................................92.3.3系统建模的方法..................................................................................................102.3.4系统建模的步骤..................................................................................................102.3.5排队系统建模的符号与分类............................................................................112.3.6M/M/c/∞/∞模型................................................................................................112.4排队系统的仿真...............................................................................................................122.4.1离散事件系统仿真..............................................................................................122.4.2FLEXSIM软件的介绍...........................................................................................133.数据采集与输入数据建模............................................................................................................143.1数据采集及原始数据..........................................................................................................143.1.1数据采集...............................................................................................................143.1.2原始数据...............................................................................................................143.2输入数据建模.......................................................................................................................153.2.1仿真方案设计..........................................................................................................153.2.
