【摘要】：传统的装配线理论研究在快速多变的市场需求以及企业不断发展的要求下已不能满足要求，各生产企业对设备和设施的利用实施方面的研究明显不足，急需解决减少流水线生产时各个工序间的在制品库存数量问题以提升线体效率。平衡率能够量化反映企业设备利用率和生产能力的水平，因而作为流水线平衡水平高低的代表被广泛应用。论文以R机型装配生产线为研究对象，发现存在明显的瓶颈站位、人机利用率差以及作业工序安排不当等问题，并导致整体生产线平衡率不高。为解决这些问题，，论文首先通过学习曲线分析，重新定义了产线工时调整频率；其次以x-σ（平均数与标准差）统计法重新确定工时量测值，明确改善前产线节拍以及生产能力；最后运用工业工程理论中ECRS（删减Eliminate,合并Combine,重组Rearrange,简化Simplify）和人机操作分析方法提升了裁板、点胶、静电袋封口、锁螺丝、包装、测试等瓶颈站的产能。经过一系列改善后，R机型装配生产线平衡率和生产能力提升了约1.9倍，同时节省了人力和设备成本。
[Abstract]:The traditional assembly line theory research has been unable to meet the requirements under the rapid and changeable market demand and the continuous development of enterprises, and the research on the use and implementation of equipment and facilities in various production enterprises is obviously insufficient. It is urgent to solve the problem of reducing the quantity of in-process inventory between the various processes of pipeline production in order to improve the line efficiency. The balance rate can quantitatively reflect the level of equipment utilization and production capacity of the enterprise. Therefore, as the representative of pipeline equilibrium level, it is widely used. This paper takes the R model assembly line as the research object, and finds that there are some problems such as obvious bottleneck position, poor man-machine utilization ratio and improper arrangement of the operation procedure, which leads to the low balance rate of the whole production line. Firstly, through the analysis of learning curve, the paper redefines the adjustment frequency of production line man-hour, then redetermines the measured value of man-hour by means of the statistical method of x- 蟽 (mean and standard deviation), and clearly improves the rhythm of production line and the production capacity. Finally, ECRSs (Delete Eliminate, merge Combine, Rearrange, simplify Simplify) and man-machine operation analysis methods in industrial engineering theory are used to improve the capacity of cutting board, dispensing, electrostatic bag sealing, locking screw, packaging, testing and so on. After a series of improvements, the balance rate and production capacity of the R model assembly line have been increased by about 1.9 times, and the cost of manpower and equipment has been saved.
