摘要
对某发动机总装车间充分调研,导入和实施拉动式看板生产系统,并进行仿真优化,解决该车间传统推动式生产系统存在生产效率低下,设备利用率低,订单平均等待时间长等问题。对导入看板后的生产系统仿真设计,可得出平均订单延迟时间大大减少,设备利用率提高,产品产量大幅增加,车间综合生产效益得到明显改善。进一步仿真优化,研究安全系数和变异系数对看板生产系统的系统产出量,在制品库存,订单平均等待时间,设备稼动率等绩效指标的影响,为实施方案参数选取提供参考。
Based on thorough investigation for an engine assembly workshop, Kanban production system was impor- ted and carried out. Some problems caused by implementing traditional push system, such as low production effi- ciency and equipment utilization rate and long average waiting time of order were solved by simulation and optimiza- tion. By comparing various performance indicators Kanban production system implemented before and after, it draws some conclusions that average order delay time is greatly reduced; the equipment utility rate of workshop is increased and comprehensive production benefit of workshop is improved obviously. Meantime, using parameter op- timization, it studied further that the different values of safety factor and variation coefficient influence on perform- ance indicators, such as throughput, work-in-process, average waiting time of order and operation rate etc. , of Kanban production system, which will provide a reference for parameter selection of implementation scheme.
