[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.
