【摘要】：本文作者所工作的公司是某集团的核心支柱企业，销量、收入、利润、单位面积产出等各项综合指标位列全球工程机械行业前列。作者利用在公司学习工作的机会，，将所学的工业工程知识运用于实践之中，对本公司六分厂的转台装配线的现状、线平衡进行分析，经过个人观察、研究，并与现场工人、生产管理人员进行紧密接触和沟通，再结合多年工作经验，收集到了大量的一线资料，综合分析发现了公司转台装配线在工位划分、货物摆放、人员分配、行车调度方面存在的问题。因此，对线平衡问题进行研究，对公司具有很大的现实意义。本文主要对转台装配线线平衡进行研究。装配线平衡就是为了解决工序间作业负荷不均衡的问题而提出的，它是现场IE的一种管理手法，也是解决装配线负荷平均化这一影响装配线效率关键问题的重要方法。本论文从分析转台线瓶颈工位，计算装配线平衡率着手，通过5wlH法及EcRs四项原则对转台装配线的瓶颈工位进行改善，使各工位得到均衡。然后对起重机转台装配线进行线平衡仿真：通过对转台装配线现场布局及物流情况进行现场仿真，并对装配线进行物流及信息流仿真，得到可比性数据，进行仿真结果分析并实施改善。最后确立起重机转台线标准作业，根据线平衡的改善及各工位操作内容制定各工位标准作业要领书。
[Abstract]:The company in which the author works is the core pillar enterprise of a certain group. The sales volume, revenue, profit, output per unit area and other comprehensive indexes rank among the top in the global construction machinery industry. Taking advantage of the opportunity of studying and working in the company, the author applies the industrial engineering knowledge he has learned in practice, analyzes the present situation and line balance of the turntable assembly line of our company's sixth branch factory, after personal observation, studies, and works with the workers on the spot. Production management personnel are in close contact and communication, combined with many years of work experience, collected a large number of front-line data, comprehensive analysis found that the company turntable assembly line in the division of work, goods placement, personnel distribution, Problems in vehicle scheduling. Therefore, the study of line balance is of great practical significance to the company. This paper mainly studies the balance of turntable assembly line. The balance of assembly line is put forward to solve the problem of unbalanced work load between working procedures. It is a management technique of IE on the spot and an important method to solve the key problem that affects the efficiency of assembly line such as average load of assembly line. In this paper, the bottleneck work station of turntable line is analyzed, the balance rate of assembly line is calculated, and the bottleneck work station of turntable assembly line is improved by 5wlH method and EcRs principle, so that each station can be balanced. Then carry on the line balance simulation to the assembly line of the crane turntable: through the field simulation to the layout and the logistics situation of the assembly line of the turntable, and carry on the logistics and information flow simulation to the assembly line, get the comparable data. Analysis of simulation results and implementation of improvement. Finally, the standard operation of the crane turntable line is established, and the standard operating essentials of each station are formulated according to the improvement of line balance and the operation content of each station.
