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)

(Kanban size) = 110 × (2 + 1) + 50 = 380 units

(Number of cards) = (kanban size) ÷ (container size) = 380 ÷ 25 = 15.2 = 16 cards

(Quantity per container) = (container size) = 25 units

Note: To create a fewer number of cards, increase the container size in the Kanban Size Calculation Parameter Definition program.
