Example

Products A01 B02 C03 D04 TOTAL

Daily Requirement 300 240 180 60 780

Quantity Per Pack 15 15 15 15 60

# of kanbans 20 16 12 4 52

Production time: 8hrs x 60 min = 480 min2 breakfast 15 min= -30 minRest 10 min= -10 min

---------------440 min

440 min x 60 x2 = 52,800 seconds


9/14

9

Takt time= 52.800 seconds / 780 units =67.6 seconds

Pitch= 67.6 sec. x 15 units = 1,014 seconds or 16.9 min.

So:

The leveling of the production is to be achieved as follows:

Product Quantity

A01 20

B02 16

C03 12
