This paper describes a practical approach to determine the optimal kanban size via simulation, with one of the objectives of being to achieve 100% fill rate. In a single product manufacturing system, although the trends of the performance measures for these two systems (i.e., Pull and Hybrid) are similar, the values of the performance measures differ significantly (see Fig.6-11). The impact of increasing the kanban size on various performance measures are summarized as follows: ตาราง
