Answer:6 kanban containers are needed
Explanation: Using the formula
Number of kanban containers =( dL + S)/C
Where
Average demand, d = 200
Lead time, L = 2 days
Safety stock is 1 day, S = 200 units
Quantity in containers, C = 100
Number of kanban containers = dL + S/C
= (200 x 2 + 200)/ 100 =400+200/100
= 600/100 = 6
Therefore 6 kanban containers are needed
