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。
Abstract:
Based on thorough investigation for an engine assembly workshop,Kanban production system was imported and carried out.Some problems caused by implementing traditional push system,such as low production efficiency and equipment utilization rate and long average waiting time of order were solved by simulation and optimization.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 optimization,it studied further that the different values of safety factor and variation coefficient influence on performance 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.
