【摘要】：生产流程是制造企业经营中的一个重要环节,是指在生产工艺中,从原料投入到成品产出,通过一定的设备按顺序连续地进行加工的过程。也指产品从原材料到成品的制作过程中要素的组合。生产流程优化是企业生产持续改善的一个重要指标,企业通过生产流程优化,可以提高生产效率、减少浪费、降低库存、提高产能,进而提高对市场变化的适应度,增强企业的核心竞争力。本文目的是根据SLSP有限公司预精焊分厂螺旋焊管生产线的实际情况,对生产线流程的现状进行详细的分析,最终提出生产流程优化的方案,并寻求优化后的最大产能。本文从生产优化的理论和仿真模拟的理论出发,结合预精焊螺旋焊管生产线的特性与实际情况,确定了生产流程优化的主要研究内容。在分析预精焊螺旋焊管生产线时,首先分析了此类产品线的特点,同时对生产线的具体工艺流程做了分析,另外,还对该生产线中人员和设备状况,以及在生产流程中出现的主要问题进行了分析。在生产设备布置与仿真模型建立中,根据预精焊生产设备特点,分别介绍了各个生产部分的主要工作,和根据工作特点选取了不同的仿真模块来构建基于Dosimis-3软件1下的整个生产系统的仿真模型。在产能瓶颈问题的分析中,根据运行仿真模型的结论和数据分析,找出瓶颈工位,找出造成瓶颈的原因,并提出解决瓶颈的方法。在仿真优化过程与分析中,通过改变钢管流向的策略,和提高技能及产品合格率的方法优化了系统中的瓶颈,并通过系统再运行加以验证。另外,通过仿真系统分析了系统中关键工位的作业率,并且提出整套方法来优化作业率。最终通过系统的再次运行找出优化后的系统最大产量。
[Abstract]:Production process is an important link in the management of manufacturing enterprises. It refers to the process of continuous processing from raw materials to finished products through certain equipment. Also refers to the production of products from raw materials to finished products in the process of the combination of elements. Production process optimization is an important index for continuous improvement of enterprise production. Through optimization of production process, enterprises can improve production efficiency, reduce waste, reduce inventory, increase production capacity, and then improve the adaptability to market changes. Enhance the core competitiveness of enterprises. According to the actual situation of spiral welded pipe production line of SLSP Co., Ltd., this paper analyzes the current situation of production line process in detail, and finally puts forward the scheme of production process optimization, and seeks for the maximum production capacity after optimization. Based on the theory of production optimization and the theory of simulation, combined with the characteristics and practice of pre-welded spiral welded pipe production line, the main research contents of production process optimization are determined in this paper. When analyzing the production line of pre-finely welded spiral welded pipe, the characteristics of this product line are analyzed first, and the specific technological process of the production line is also analyzed. In addition, the personnel and equipment in the production line are also analyzed. And the main problems in the production process are analyzed. In the production equipment layout and simulation model establishment, according to the characteristics of pre-precision welding production equipment, the main work of each production part is introduced respectively. According to the working characteristics, different simulation modules are selected to build the simulation model of the whole production system based on Dosimis-3 software 1. In the analysis of the bottleneck problem, according to the conclusion of the simulation model and the data analysis, find out the bottleneck position, find out the cause of the bottleneck, and put forward the method to solve the bottleneck. In the process and analysis of simulation optimization, the bottleneck of the system is optimized by changing the flow direction of the steel pipe and improving the skill and the qualified rate of the product, and it is verified by the rerunning of the system. In addition, the work rate of key stations in the system is analyzed by simulation system, and a whole method is proposed to optimize the work rate. Finally, the maximum output of the optimized system is found through the system running again.
