未来状态图跑起来:超市补货、先进先出、一个定拍工位Run the future state: supermarket replenishment, FIFO, and one pacemaker
客户每 10 秒取 1 件;装配 C/T 8 秒,冲压 C/T 4 秒。切换推动与拉动,盯住装配前缓冲、三层超市、FIFO 道和逆物流回到冲压的青色看板:产出可能一样,货等人的形态完全不同。The customer takes one part every 10 seconds; assembly runs at an 8-second C/T and stamping at 4 seconds. Switch between push and pull, then watch the assembly buffer, three-level supermarket, FIFO lane, and cyan Kanban returning upstream. Output can match while the shape of waiting inventory changes completely.
💡 跑完看数据:出货一样多,在制品形态不一样💡 Run it, then read the numbers: same shipments, different WIP behavior

模型规则:推动式冲压每 120 秒整批压入 12 件;拉动式只有 Pacemaker 接指令,FIFO 未满才装配、超市少 1 件才按冲压 C/T 4 秒补 1 件。两种方式都由客户每 10 秒取货定拍。Model rule: Push releases a full batch of 12 every 120 seconds. Under pull, only the pacemaker receives the schedule: assembly runs only when FIFO has space, and stamping replaces each supermarket withdrawal at a 4-second C/T. Customer pickup every 10 seconds paces both systems.
只给 Pacemaker 下指令;超市管补多少,FIFO 管先后顺序。Schedule only the pacemaker; the supermarket controls quantity and FIFO protects sequence.
