装配生产线平衡的研究
摘要
随着快速多变的市场需求及企业的生长,在流水线生产的模式下,如何提高生产线的整体效率,淘汰工序间的在制品,以及追求同步化生产越来越受到重视,,并限制着生产线生产能力的提高。
论文通过对装配生产线平衡的研究,结合自身企业产物的特点,对现有生产进行了改进,说明了现有产业工程技能在生产线平衡改进中的作用。首先,本文叙述了生产线平衡理论及评价方法,及影响线平衡的要素,同时凭据产业工程底子理论界说了改进生产线平衡的方法。对付本文所讨论的机种N机型,针对其线平衡率不高的问题,通过阐发现状,找出了问题所在：工时量测不公道；有明显的瓶颈站位存在；人机利用率较差；作业工序摆设不妥。然后凭据生产线平衡的步调及要领,运用了统计阐发的x-σ管束要领,及学****曲线的理论,重新确定了工时；并凭据工序节拍均衡的原则,通过对产业工程理论中ECRS及人机操纵阐发要领的运用,调解了工序内容,使各工序节拍趋于一致,且精减了部分站位,节省了人力,设备本钱,并使生产能力得到了提高。
论文的运用要领：
-σ管束要领,来对工时量测进行盘算。
,结合实际生产状况,适时进行工时改进,低落生产线工时,提高了人均产出。
,调解测试站位的工时及人机分派。
要害词：生产线平衡,工序节拍,人机操纵阐发,x-σ管束,学****曲线
RESEARCH ON THE ASSEMBLY
PRODUCTION LINE BALANCE
ABSTRACT
To meet the variable requirement of the market,it becomes more andmore important to improve the efficiency of production line,decrease thestorage of half-goods and attain equalization for the is an popularindex for the company to make the assessment on a pipeline,and it is alsoaffect the line capability.
Through studying on the theory of the assembly line balance andcombining the the characteristic of the the real production line,we find it ishelpful to practice the industry engineering ,this paper hasrecounted the theory of the pipeline balance and of how to make evaluationfor by the theory,the paper defined the detail methods to improve theline the model of N which is one of the most important productsin our company,we found some problems on the pipeline by analyzing thesituation：unreasonable measurement for cycle time；obvious neckstation；low efficiency for the use of man-machine；improper arrangementfor the operation.
By steps and methods of assembly line balance,the paper practice thestatistic method of x-σcontrol and the study-curve,so new man-hour following ECRS(Eliminate,Combine,Rearrange,Simplify) principle of IE and man-machine the method,we adjusted operation contentand make the operation
