Question

If a company is implementing a Kanban system and has captured the following data, how many
Kanbans do they need in their system? The company is conservative and does not want to run
out of product.
a. Container size = 840
b. Lead time = 3 days
c. Usage = 900 per day
d. Safety stock = 60

Answer 1

To calculate the number of Kanbans needed:

Number of Kanbans = (Usage * (Lead time + Safety stock)) / Container size

Given:

a. Container size = 840

b. Lead time = 3 days

c. Usage = 900 per day

d. Safety stock = 60

Number of Kanbans = (900 * (3 + 60)) / 840

Number of Kanbans ≈ (900 * 63) / 840

Number of Kanbans ≈ 56700 / 840

Number of Kanbans ≈ 67.5

Since we can't have a fraction of a Kanban, the company would need 68 Kanbans to ensure they don't run out of product.
