【摘要】：企业生产过程管理粗放,各生产环节产能不均衡,人员及设备利用率低是目前企业生产管理面临的实际问题。如何系统的研究企业生产过程产能不高的影响因素,并对瓶颈环节进行深入分析,采取措施提高瓶颈环节产能是企业必须解决的问题。近年来随着工业工程技术的应用推广,逐渐体现了其在解决上述问题方面的重要作用。本文的研究对象为宁夏华夏电源有限公司,该公司总体产能满足不了订单要求,各工序产能不均衡,特别是装配环节产能一直制约公司产能提升,生产过程操作人员和设备的利用率低。针对这一问题本文运用工业工程相关理论方法,研究产能问题产生的主要原因,并提出改善方案,取得了比较好的效果。论文主要内容如下：(1)首先通过各工序产能实际情况确定制约公司产能的短板在于蓄电池组装区,确定了2#号装配线为主要问题点。(2)针对2#号装配线,运用时间研究方法确定各作业时间,计算生产线平衡率,确定问题工位。运用流程程序方法对整个装配流程进行分析,运用5W1H法提问总结存在的问题；运用联合作业分析,分析瓶颈工位存在的问题。(3)在流程程序分析及联合作业分析基础上,运用ECRSI原则,对2#号生产线中存在的人机利用率低,工作负荷不均衡等现象进行改进。通过提升操作人员和生产设备利用率,实现提高装配线产能的目标。(4)针对生产现场的工作环境问题,生产设备原材料的摆放,生产区域的安全问题等做出改进。(5)对改进后效果进行评价。改进方案实施后,铅酸蓄电池装配和组装区域生产线的人机利用率得到了明显提高,产能大幅度提升,降低了生产成本,产品生产周期明显缩短,操作人员的工作环境有了大幅改善。
[Abstract]:Extensive production process management, unbalanced production capacity and low utilization ratio of personnel and equipment are the practical problems faced by enterprise production management at present. How to systematically study the influence factors of low production capacity in the production process, and analyze the bottleneck link in depth, and take measures to improve the bottleneck capacity is the problem that enterprises must solve. In recent years, with the application and popularization of industrial engineering technology, it has gradually reflected its important role in solving the above problems. The research object of this paper is Ningxia Huaxia Power supply Co., Ltd., the overall capacity of the company can not meet the requirements of the order, the production capacity of each process is uneven, especially the assembly capacity has been restricting the company's capacity increase. Low utilization of production process operators and equipment. In view of this problem, this paper studies the main causes of the productivity problem by using the relevant theories and methods of industrial engineering, and puts forward the improvement scheme, which has achieved better results. The main contents of this paper are as follows: (1) firstly, the short plate that restricts the production capacity of the company is determined by the actual situation of each process capacity, and the assembly line of 2# is determined as the main problem point. (2) aiming at the assembly line of 2#, Time research method is used to determine the working time, to calculate the balance rate of production line, and to determine the problem position. The whole assembly process is analyzed by the process program method, the existing problems are summarized by the 5W1H method, the problems existing in the bottleneck station are analyzed by using the joint operation analysis. (3) on the basis of the process program analysis and the joint operation analysis, By using ECRSI principle, the phenomena of low man-machine utilization ratio and unbalanced workload in the product line No. 2# are improved. By improving the utilization ratio of operators and production equipment to achieve the goal of improving assembly line capacity. (4) to solve the problem of working environment on the production site, the raw materials of production equipment are placed. Improve the safety of production area. (5) evaluate the effect of the improvement. After the implementation of the improved scheme, the man-machine utilization ratio of the production line of lead-acid battery assembly and assembly area has been obviously improved, the production capacity has been greatly increased, the production cost has been reduced, and the production cycle of the product has been significantly shortened. The working environment of the operators has been greatly improved.
