Question

A bottling plant fills 2,400 bottles every two hours. The lead time is 40 minutes and a container accommodates 120 bottles. The safety stock is 10 percent of expected demand. How many kanban cards are needed?

Short answer

In this situation, Karban card sets are required.

Step-by-step solution

Equation through which Karban card set is calculated

K = DL(1+S)/C

Where K = number of karban cards needed

D =average demand

L =lead time

S =safety stock

C = container size

Calculate the Karban card set

D =2400

L =40

S =0.1 (as a percent of 10)

C =120

K= 2400 x 40(1+0.1)/120

K= 105,600/120

K= 880

So, 880 Karban card sets are required.
