Answer:
Kanban container size = 52 units
Number of kanbans needed = 8
Explanation:
As per the data given in the question,
Calculation for Economic Production Quantity :
Q^2 = 2 Ă— Annual demand Ă— Setup cost Ă· (Annual holding cost Ă—(1 - (daily demand Ă· daily production)))
Q^2 = 2 Ă— 20,000 Ă— 20 Ă· ($400 Ă— (1 - (80 Ă· 320)))
Q^2 = 800,000 Ă· 300
Q = Kanban container size = 52 units
Number of kanbans needed = ( Demand during lead time+safety stock ) Ă· container size
= ((5 Ă— 80) + 50) Ă· 52
= 8.65
= 8 kanbas
