The Study Of Improving Production Line Based On Arena Simulation

With the development of science and technology, the competition of the industry becomes more and more fiercely. In order to not be eliminated in the competition, all enterprises strive to improve their own competitiveness in the market, by lowering production costs, improving production efficiency. In order to achieve this goal, many enterprises have the production line in the production operation mode, or manual operation, or human joint operation, thus the production process is subdivided, the production efficiency is improved. After the effective segmentation of the production process, station workers perform their respective duties, not only reduces the individual worker’s operation difficulty, but also reduce the specific production time of each station workers, but there is a problem:After the process is decomposed, because of the different work of each station workers lead to the difference of operating time, so that part of the work station is in busy condition all the time, while some other stations are idle. At last the production efficiency of the production line is negatively affected, resulting in low efficiency.In this article, in order to be in connection with one specific assembly process of a large manufacturing plant in Sichuan enterprises ZL50E-3loader assembly production line, making use of the Simulation Technology of the Arena modeling and simulation, and means for improvement of industrial engineering to analyze and improve the assembly line. Through the assembly line observed and analyzed, the corresponding process chart has been drawn. In the simulation model, in order to use the mathematical expression of station operation time, station operation time has been applied to repeated measurement, in order to comprehensive consideration of the accuracy of the data and the cost of observation to achieve an optimal value, the method of error limit has been applied to determine the observation times of specific station. With the data simply filtered, the collected data has been analyzed and dealt with by the analysis of the software of the simulation software of Arena, analyzing of the best fitting distribution function of operation time. After that, the simulation model of the assembly line has been established with the application of Arena. The model has been set up and run, and the results of the simulation have been analyzed. The bottleneck process has been found out. The bottleneck process has been improved by studying the method of the application of Industrial Engineering. The operation time of workers’ has been effectively reduced, and the cycle time has been shortened. Based on the improved the data of production line, the simulation model established has been Corrected. Through contrasting and analyzing the results of the simulation before and after improvement, the operation time of the whole of production line has been Saved about20seconds, Improved the production.
