客车厂多品种小批量混流生产线设计说明书学校代码：10128摘要现在汽车市场的细分化和汽车产品需求的多样化，使得企业在日趋激烈的市场竞争中的发展面临越来越多的考验，汽车制造企业为适应当前的市场将多品种混流生产线作为一个竞争手段。本文以某客车厂为背景，提出设计一条混流生产线以适应当前市场。根据这个企业，首先结合两条生产线产品类型和产品生产工艺绘制两产品作业先序图，应用工业工程思想和技术，确定产品生产中每个作业要素的标准作业时间，并绘制出总的作业先序图。然后计算节拍，根据厂房的长度和客车车型长度，确定大致的工作地数，同时以工作地时间均衡为目标，以生产工艺为基础人为地进行作业要素分配和人员分配，确定工作地数和节拍时间，达到生产线平衡的目的。最后根据最小生产单元排序法，计算所有的最小生产单元序列，并应用Flexsim软件仿真技术进行投产排序，选择用时最少的序列为最佳投产序列，解决了投产排序问题。关键词：客车装配生产线，生产线平衡，投产排序AbstractNowcarmarketdifferentiationandautomobileproductsdemanddiversification,makestheenterpriseintheincreasinglyfiercemarketcompetitionfacingmoreandmoretestofautomobilemanufacturingenterpriseinordertoadapttothecurrentmarketwillbemorevarietiesofmixedflowproductionlinesasameansofcompetition.Basedonabusasthebackground,thispaperproposedamixedflowproductionlinedesigntoadapttothecurrentmarket.Accordingtotheenterprise,combiningwithtwoproductionlinesfirstproducttypeandproductproductionprocessmapfirstordertwoproducts,applicationofindustrialengineeringideasandtechnologies,determineproductproductionineachjobelements,standardworktime,anddrawouttheoveralloperationsequencediagramfirst.Andcalculatethebeat,accordingtotheworkshopandthelengthofthelengthofpassengercarmodels,determinetheroughwork,atthesametimetoworkingtimebalanceasthegoal,tooperateonthebasisoftheproductionprocessartificiallyelementdistributionandpersonnelallocation,determinetheworknumberandtakttime,achievethegoalofproductionlinebalancing.Accordingtotheminimumproductionunitsortingmethod,calculatestheminimumproductionunitseries,andappliedtoproductionsortFlexsimsoftwaresimulationtechnology,takestheleastsequenceforoptimalproductionsequence,productionschedulingproblemsaresolved.Keywords:passengercarassemblyline,productionlinebalance,productionscheduling目录第一章概述.............................................................11.1论文的研究背景....................................................11.2研究的目的与意义..................................................11.3国内外研究现状....................................................21.3.1混流线的平衡.................................................21.3.2混流线投产排序...............................................51.3.3混流线的仿真优化..............................................51.4论文研究的主要内容和方法.........................................61.5本章小结.........................................................7第二章某企业客车生产线现状.............................................82.1生产车间现状.....................................................82.2生产线状况.......................................................102.3小结.............................................................11第三章客车生产线设计..................................................123.1装配生产线平衡优化设计理论.......................................123.1.1装配生产线平衡问题的基本理论..................................123.2客车装配生产线平衡优化.............................................
