拉动式生产法是指生产并非按计划从前向后进行，而是根据订单从后向前进行。前道工序由后道工序触发，即后道工序在必要的时刻向前道工序领取必要数量的必要零部件（或物料），接着前道工序只需生产被领取走的那部分零部件（在数量和种类上相同）即可。拉动式生产法(Pull) The pull production method means that production is not carried out from the front to the back as planned, but proceeds from the back to the front according to the order. The previous process is triggered by the subsequent process, ie, the next process takes the necessary number of necessary components (or materials) to the process at the necessary time, and then the previous process only needs to produce the part of the component that was taken away ( Same quantity and type).
