Kanban Equation 2: Fixed Container Size and Average Demand

Because the demand split percentage is 100 percent, the average daily demand remains the same.

The Kanban Master table contains three kanban records for the same supplying branch, supplying location, consuming branch, consuming location, and item number. The demand must be distributed evenly among the records.

(Average daily demand) = (average daily demand) ÷(number of similar kanban records)

(Average daily demand) = 198.75 ÷ 3 = 67

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

(Kanban size) = 67 × (2 + 1) + 50 = 251 units

The maximum kanban size is defined as 60 in the Kanban Size Calculation Parameter Definition program. Therefore, the kanban size is 60, because 251 is greater than 60.

(Number of cards) = (kanban size) ÷ (container size) = 60 ÷ 50 = 1.2 = 2 cards
