Kanban Equation 1: Fixed Container Size and High Demand

This equation calculates the number of cards when the kanban quantity is fixed to the container size. Use this equation when item demand fluctuates significantly:

(Kanban size) = (high daily demand) × [(lead time delivery (days)) + (scan delta days)] + (safety stock)

(High daily demand) = ( (Highest period demand in the Periods in MRP Window) x (vendor split percent) x (demand split percent for the consuming location)) ÷ (days built per period)

The system then calculates the number of kanban cards by dividing the kanban size by the container size.
