【摘要】：制造业是一个国家的基础性和支柱性产业,它能够准确的反映出一个国家生产能力、国民经济和综合国力的水平。2011年,世界上最大的制造业国家已经是中国,在科学技术水平日新月异、飞速发展的现在,制造业已经给中国带来了巨大的发展空间和可观的利润。从制造业的发展初期到现在,流水线在工业生产中凸显出的作用日趋明显,并且逐步成长为工业生产中不可缺少的一部分,它不仅能够使产品生产的质量和生产的效率大大提高,也能够大大的节约人力资源。作为一种生产组织形式,流水生产线的高效性和先进性一直在生产中发挥着重要作用。早在21世纪初,流水生产线就开始应用于汽车的装配及制造,从此揭开了大规模生产新的一页,制造业前所未有的辉煌被流水生产线带来。目前,采用流水线的方式生产制造出来的产品在市场上占绝大多数。在流水线生产中,流水线的平衡率是反映一个产线的生产效率和生产质量的重要指标,也是衡量产线生产效能的重要指标。产线的静态平衡率能反映出产线在理想状态下运作的生产效率,而动态平衡率则能反映出产线在受外界因素干扰下的实际平衡率。本论文旨在探究生产线平衡率的波动因素,并将这些因素引入到平衡率计算中,形成生产线多因素动平衡率模型和周期工时的测算方法,并且通过改善这些因素,使生产线效率有所提高。通过在F公司Alvin装配线的实习调研,发现F公司利用现有方法测量与计算出的平衡率与观察到的实际不符,并且装配线的平衡率和产量较低。分析其中的原因,针对平衡率与实际不符的问题,提出了一套测算周期工时的新方法,并建立了多因素动平衡率模型,通过实测数据验证并用Flexsim软件进行仿真,证明该模型适用于Alvin产品装配线。针对动平衡率和产量较低问题,对Alvin产品装配线现场进行了改善,改善后效果显著,平衡率和产量都得到了提高。
[Abstract]:Manufacturing is the basic and pillar industry of a country. It can accurately reflect the level of a country's productive capacity, national economy and overall national strength. In 2011, the largest manufacturing country in the world was China. With the rapid development of science and technology, manufacturing industry has brought huge development space and considerable profits to China. From the beginning of the development of manufacturing to the present, the role of assembly line in industrial production has become increasingly obvious and has gradually grown into an indispensable part of industrial production. It can not only improve the quality and efficiency of product production, but also save human resources. As a form of production organization, the efficiency and advancement of the production line has been playing an important role in production. As early as the beginning of the 21st century, the running water production line began to be applied to the assembly and manufacture of automobiles. Since then, a new page of large-scale production has been opened, and the unprecedented brilliance of the manufacturing industry has been brought by the flowing water production line. At present, the use of assembly lines to produce the products made in the market accounted for the overwhelming majority. In the production of assembly line, the balance rate of assembly line is an important index to reflect the production efficiency and quality of a production line, and also an important index to measure the efficiency of production line. The static equilibrium rate of the production line can reflect the production efficiency of the production line operating under the ideal condition, while the dynamic equilibrium rate can reflect the actual equilibrium rate of the production line under the interference of external factors. The purpose of this paper is to explore the fluctuating factors of production line equilibrium rate, and to introduce these factors into the calculation of balance rate, to form a multi-factor dynamic balance rate model of production line and the calculation method of periodic man-hour, and to improve these factors by improving these factors. The efficiency of the production line has been improved. Through the practice investigation in the Alvin assembly line of company F, it is found that the balance rate measured and calculated by the existing methods is not in accordance with the observed balance rate, and the balance rate and output of the assembly line are lower. By analyzing the reasons, aiming at the problem that the balance rate is not in accordance with the actual situation, a new method of measuring cycle time is put forward, and a multi-factor dynamic balance rate model is established. The model is verified by the measured data and simulated with Flexsim software. It is proved that this model is suitable for Alvin assembly line. Aiming at the problem of low dynamic balance rate and low output, the field of Alvin assembly line is improved, the effect is remarkable, and the balance rate and output are improved.
