汽车车身装配线准时配送系统分析与改进

1本科论文不怕查重汽车车身装配线零部件准时配送系统分析与改进2014年6月2摘要随着经济全球化和一体化的不断发展，我国汽车工业快速发展，但同时也面临着国际化竞争的巨大挑战，这对我国汽车行业企业的生产管理方式和物料配送方式提出了更高的要求。JIT准时化生产方式能够有效降低企业库存，优化企业的资金流，提高企业生产效率，已在汽车制造企业中广泛应用，但由于配送分拣现场的不稳定和供应商运输的不确定性，经常会导致部分车型专用件、按顺序排列的某些颜色零件的短缺和大件零件的空间占用大等问题。本文针对广汽乘用车车身装配零部件配送系统中的存在的问题和浪费现象，以实现车身装配线物料的准时配送、降低物流成本为研究目的，利用同步配送的理论和基础工业工程的改善手法，制定配送系统的优化方案，来降低现场库存，优化物料信息反馈机制和减少作业过程中的浪费。具体研究步骤：首先，分析现有的汽车车身装配线零部件配送系统的配送方式、作业流程和信息传递机制，找出现有配送系统中存在的问题，其次，对问题进一步深入分析，找到导致问题产生的主要原因，确定改善的主要方向，然后，结合车身装配线混流生产的特点，以先进的物流管理理念和信息化手段作为支撑，从车身装配线配送系统的配送方式、配送信息传递方式、配送作业流程三个方面提出优化方案，并对改善方案产生的效益进行总结和评价。关键词：汽车车身装配线、零部件配送、JIT配送、同步配送、基础工业工程3AbstractWiththedevelopmentofeconomicglobalizationandtheintegrationofChina’sautomobileindustryhasbeenmorerapiddevelopment,butalsointensifiedinternationalcompetitionsituationofChina’sautomobilemanufacturingenterpriseproductionmanagementandmaterialdistributionmanagementproposednewrequirements.JITproductionmethodscaneffectivelyreduceinventory,optimizecashflow,improveproductionefficiency,hasbeenwidelyusedinautomobilemanufacturingenterprises.However,duetotheunstabledistributionsitesortingandtransportproviders’uncertainty,itwillleadtospaceshortagesofspecificpiecesandlargepartsofcertaincolorsinsequenceoccupylargespaceofthesite.Inthepaper,inordertoachieveJITdeliveryofmaterialsofbodyassemblyandreducelogisticscostsforresearchpurposes,aimingGAMCbodyassemblypartsdistributionsystemproblemsandwastephenomenon,synchronizeddistributiontheoryandtechniquesofindustrialengineeringisusedtodevelopdistributionsystemoptimizationprogramsforreducingon-siteinventory,optimizingmaterialinformationfeedbackmechanismandreducingwasteduringtheoperation.Specificresearchsteps:Firstly,toanalyzedistributionmethods,processesandinformationdeliverymechanismoftheexistingassemblylineautomobilebodypartsdistributionsystemtoidentifyexistingproblemsinthedistributionsystem.Secondly,toanalyzetheexistingproblemsfollowedbyfurthertofindthemaincauseoftheproblemsanddeterminethemaindirectionofimprovement.Andthen,combinedwiththecharacteristicsofthebodyassemblylinemixedproduction,advancedlogisticsmanagementconceptsandinformationtechnology,toproposeoptimizationprogramsofthebodyassemblylinedistributionsystemdistributionfromdistributionmethods,distributionprocessesandtransmissionofinformationdeliveryandsummarizeandevaluatethebenefitofprograms.Keyword:Automobilebodyassemblyline,Partsdistribution，JITdelivery,Synchronizeddistribution,Basicindustrialengineering4目录1绪论..................................................................11.1课题研究背景...............................................................................................................11.2研究的目的和意义.......................................................................................................21.3国内外研究现状...........................................................................................................31.3.1国外研究现状.........................................................................................................31.3.2国内研究现状.........................................................................................................31.4论文的研究思路和框架...............................................................................................42JIT配送和IE技术的基本理论............................................52.1准时化配送...................................................................................................................52.1.1基本概念.................................................................................................................52.1.2准时化配送的环境和条件.....................................................................................62.1.3准时化配送的目标.................................................................................................62.2同步配送.......................................................................................................................72.3基础IE技术..................................................................................................................82.3.15W1H提问技术......................................................................................................82.3.2ECRS四大原则........................................................................................................82.3.3程序分析.................................................................................................................93汽车车身装配线零部件配送系统的现状及问题分析.........................103.1广汽乘用车公司简介.................................................................................................103.2现有汽车车身装配线零部件配送管理流程.............................................................113.2.1汽车车身装配线配送作业流程...........................................................................113.2.2汽车车身装配线零部件配送方式.......................................................................1353.2.3配送的信息管理...................................................................................................163.3汽车车身装配线零部件配送系统存在的问题及原因.............................................184汽车车身装配线零部件配送系统改进.....................................2
