【摘要】：过量堆积的在制品占用大量空间、降低企业资金周转率,造成企业成本增加。为解决企业普遍存在的该问题并实际应用看板系统策略,重点研究在两阶段生产系统中工序间看板最优数量的确定方法。结合企业实际运作情况,考虑产品缺货成本、在制品库存持有成本、机器生产成本以及机器闲置成本在内的生产系统单位时间总成本,识别系统运行中的马尔科夫过程并应用排队理论构建成本模型,最终得到两工序之间的最优看板数量。算例分析说明了该模型的可行性和有效性。敏感性分析表明,看板数量较少时,对单位产品的缺货成本和持有成本参数的敏感度更高。另外,最优看板数量也随后工序生产速率增加而增加。
[Abstract]:Excessive accumulation of WIP occupies a lot of space, reduces the turnover rate of enterprise capital, and increases the cost of enterprise. In order to solve this problem and apply the Kanban system strategy, the method of determining the optimal number of Kanban in two-stage production system is studied. Combined with the actual operation of the enterprise, considering the total cost of production system per unit time, including product shortage cost, in-process inventory holding cost, machine production cost and idle machine cost, The Markov process in the operation of the system is identified and the cost model is constructed by using the queuing theory. Finally, the optimal number of Kanban between the two processes is obtained. The feasibility and validity of the model are illustrated by an example. Sensitivity analysis shows that when the number of Kanban is small, it is more sensitive to the cost of stock shortage and the holding cost parameter of unit product. In addition, the number of optimal Kanban also increased with the increase of production rate.
