【摘要】：随着科学技术发展,行业竞争加剧。各企业为了在竞争中不被淘汰,努力提高自身的市场竞争力,不断降低生产成本,提高生产效率,为达到这一目的,不少企业都在生产中采用流水线生产作业方式,或人工作业,或人机联合作业,使生产工艺细分,以此提高生产效率。在生产工艺有效细分后,工位上的工人各司其职,不仅降低了单个工人的操作困难程度,而且还降低了每个工位上工人的具体生产作业时间,但也出现一个问题：某个作业的工序被分解后,因为每个工位上的工人作业内容的不同而导致作业时间的不一样,这样会让部分工位一直处于忙碌状态中,而有些工位却比较闲,使整个生产线的生产效率都会受到负面影响,导致效果低下。在本文中,针对四川某大型生产制造企业的ZL50E-3装载机总装生产线上的一个车间的具体组装流程,应用Arena建模仿真技术与工业工程中的改善手段对该组装生产线进行分析并改善。对总装生产线进行观察分析,制作相应的工艺流程图。由于仿真模型中,要使用工位上作业时间的数学分布表达式,就需要多次测量工位作业时间,为了数据精度和观测成本都能综合考虑达到一个整体最优值,在本研究中采用误差界限法来确定具体工位需要的观测次数。在对数据进行简单过滤后,使用Arena仿真软件中自带的分析软件对收集到的数据进行分析处理,分析出作业时间的最佳拟合分布函数。再用Arena仿真软件建立当前组装生产线的仿真模型,然后对模型进行设置并运行,再对仿真结果进行分析,找出瓶颈工序。应用工业工程中的方法研究对瓶颈工序进行改善,有效减少了工人作业时间,缩短生产节拍。再以改善后的生产线数据来修正之前建立的仿真模型,把仿真结果与改善前的仿真结果做对比分析由理论与实践相结合,表明了仿真技术可以通过对现实生产线的仿真反应当前生产线的现状,可以由此分析出问题所在；工业工程技术可以使用方法研究与作业测量手段有效改善影响生产线生产的因素,二者相结合,可以快速找到问题并解决问题。本文中为单次生产作业中整条生产线节约了约20秒作业时间,提高了生产产量。
[Abstract]:With the development of science and technology, industry competition intensifies. In order not to be eliminated in the competition, the enterprises strive to improve their market competitiveness, continuously reduce production costs and improve production efficiency. In order to achieve this goal, many enterprises adopt assembly line production operation mode in production. Or manual work, or man-machine joint operation, so that the production process subdivision, so as to improve production efficiency. After the production process has been effectively subdivided, the workers on the work stations perform their respective duties, which not only reduces the operational difficulties of individual workers, but also reduces the specific production time of the workers at each work station. But there is also a problem: when the process of a particular job is decomposed, the work time is different because of the different contents of the workers' work at each station, which will keep some of the work stations busy all the time. Some work stations are relatively idle, so the production efficiency of the entire production line will be adversely affected, resulting in low efficiency. In this paper, according to the concrete assembly flow of a workshop in a ZL50E-3 loader assembly line of a large manufacturing enterprise in Sichuan province, the Arena modeling and simulation technology and the improvement means in industrial engineering are used to analyze and improve the assembly line. Observe and analyze the assembly line and make the corresponding process flow chart. In the simulation model, in order to use the mathematical distribution expression of the working time on the work station, it is necessary to measure the working time many times. In order to achieve the overall optimum value, the data precision and the observation cost can be considered synthetically. In this study, the error limit method is used to determine the number of observations required. After the simple filtering of the data, the data collected are analyzed and processed by using the analysis software of Arena simulation software, and the best fitting distribution function of the job time is analyzed. Then the simulation model of assembly line is established by using Arena simulation software, then the model is set up and run, and the simulation results are analyzed to find out the bottleneck procedure. The method of industrial engineering is applied to improve the bottleneck process, which can effectively reduce the working time of workers and shorten the production rhythm. Then the improved production line data is used to modify the simulation model established before, and the simulation results are compared with those before the improvement by combining theory with practice. The results show that the simulation technology can reflect the current situation of the production line through the simulation of the actual production line, and the problem can be analyzed. Industrial engineering technology can effectively improve the factors that affect the production line by means of method research and operation measurement. The combination of the two methods can quickly find the problem and solve the problem. In this paper, the whole production line is saved about 20 seconds and the output is improved.
