Kanban Equation 4: Fixed Number of Cards and Average Demand

This equation calculates the kanban quantity for a fixed number of containers with demand based on the average daily demand.

The number of cards is fixed at 10 in the Kanban Size Calculation Parameter Definition program.

(Kanban size) = (average daily demand) × [(leadtime delivery (days)) + (scan delta days)] + (safety stock)

(Kanban size) = 107.5 ÷ (2 + 1) + 50 = 372.5 =373 units

(Container size) = (kanban size) ÷ (number of containers) = 373 ÷ 10 = 37.3 = 38 units
