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发展,在流水线生产的模式下,如何提高生产线的整体效率,减少工序间的在制品,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,结合自身企业产品的特点,对现有生产进行了改善,说明了现有工业工程技术在生产线平衡改善中的作用。首先,本文叙述了生产线平衡理论及评价方式,及影响线平衡的要素,同时根据工业工程基础理论定义了改善生产线平衡的方式。对于本文所讨论的机种N机型,针对其线平衡率不高的问题,通过分析现状,找出了问题所在:工时量测不合理;有明显的瓶颈站位存在;人机利用率较差;作业工序安排不当。然后根据生产线平衡的步骤及方法,运用了统计分析的x-σ管制方法,及学习曲线的理论,重新确定了工时;并按照工序节拍均衡的原则,通过对工业工程理论中ECRS及人机操作分析方法的运用,调整了工序内容,使各工序节拍趋于一致,且精减了部分站位,节省了人力,设备成本,并使生产能力得到了提高。
论文的运用方法:
-σ管制方法,来对工时量测进行计算。
,结合实际生产状况,适时进行工时改善,降低生产线工时,提高了人均产出。
,调整测试站位的工时及人机分配。
关键词:生产线平衡,工序节拍,人机操作分析,x-σ管制,学习曲线
RESEARCH ON THE ASSEMBLY
PRODUCTION LINE BALANCE
ABSTRACT
To meet the variable requirement of the market,it es more andmore important to improve the efficiency of production line,decrease thestorage of half-goods and attain equalization for the is an popularindex for pany to make the assessment on a pipeline,and it is alsoaffect the line capability.
Through studying on the theory of the assembly line balance bining 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 pany,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(bine,Rearrange,Simplify) principle of IE and man-machine the method,we adjusted operation contentand make the operation cycle reach the improvement,weal
