Answer:

a) 3 Kanbans are required for the bakery.

b) The maximum authorized inventory is 6 Kanbans.

c)

6 Kanbans are required for the bakery.

The maximum authorized inventory is 12 Kanbans.  

Explanation:

a.

Use the following formula to calculate the numbers of Kanbans required

Numbers of Kanbans required = Average Demand x ( average setup and processing time + Current Safety Stock ) / Container quantity

Numbers of Kanbans required = 160 cups x ( ( 1/5 days )/4 x ( 1 + 8% ) ) / 3 cups

Numbers of Kanbans required = 2.9

Numbers of Kanbans required = 3 Kanbans

( Rounded to whole Kanbans )

b.

Use the following formula to calculate the maximum authorized inventory

Maximum authorized inventory = Numbers of Kanbans required x 2 = 3 Kanbans x 2 = 6 Kanbans

c.

Use the following formula to calculate the numbers of Kanbans required

Numbers of Kanbans required = Average Demand x ( average setup and processing time + Current Safety Stock ) / Container quantity

Numbers of Kanbans required = 160 cups x ( ( 3/8 days )/4 x ( 1 + 8% ) ) / 3 cups

Numbers of Kanbans required = 5.4 Kanbans

Numbers of Kanbans required = 6 Kanbans

( Rounded to whole Kanbans )

Use the following formula to calculate the maximum authorized inventory

Maximum authorized inventory = Numbers of Kanbans required x 2 = 6 Kanbans x 2 = 12 Kanbans
