Research on takt time balance of flywheel production line based on witness software

车间的生产节拍平衡决定了企业生产效率的高低,是解决制造业车间面临的主要问题的最佳途径,研究了某飞轮生产线生产节拍的平衡问题。对某飞轮生产线生产现状进行分析,测定工序作业时间,应用Witness软件进行仿真建模,发现瓶颈环节与利用率不足等不平衡现象,运用生产节拍平衡方法等改进生产线,达到日产目标,消除瓶颈环节,使机器与人员利用率均衡。通过比较生产节拍平衡前后的相关参数,生产线改善效果明显,生产效率得以提高,进而降低企业成本。

The takt time balance of workshop production determines the level of production efficiency,which is the best way to solve the main problems facing with the manufacturing workshop.First the balance problems of takt time of a flywheel production line are studied.By analyzing the production status of some flywheel production line and measuring the process operating time,the simulation model is constructed using the Witness software.Then the bottleneck processes of production line and utilization inadequate are found by simulating modeling.And the production line is improved by using tskt time balancing method,which achieves the target and makes the bottleneck processes be eliminated with the utilization rate of machine and personnel being balanced.Through comparing the relevant parameters before and after the balance,the improvement results of production line are found to be significant and the production efficiency is improved,thus the production costs are reduced.
