The main performance measures three factors：number of containers in kanban system、pouring cup、and melting furnace. We define that the pouring cup level is Base for Economic Lot Size；and the melting furnace level is Economic Lot Size Restrictions. According to the above mentioned factors of the number of different standards for performance indicators to optimize.Using the Arena simulation modeling the multistage single -card kanban system，and setting limits on type and target type to find out the best operating level in any possible suggestions. The indicators is Input、Output、average WIP、Total Time、Turnover、and Profit. After modeling we use the “OPTQuest for Arena” to profit-maximizing，then compared with the push system model the increase of efficiency. The batch size associated with each card has a significant effect on the performance of the Kanban system. And the effect of the number of Kanban cards in the system is also significant. In fact, since the batch size and lead times are correlated, its effect is much more complex than the number of containers in the system.
