Quizplus · Accepted Answer

To calculate the number of kanbans required, we need to use the following formula: 
Number of kanbans = (Daily demand x Lead time) + Safety stock / Quantity per kanban 
Plugging in the given values, we get: 
Number of kanbans = (5 x 7) + 1 / 8 
Number of kanbans = 35/8 
Number of kanbans = 4.375 
Since we cannot have a fraction of a kanban, we will round up to the nearest whole number, which gives us 5 kanbans. Therefore, the correct answer is option C, 5.

Lead Time for Computers Is 7 Days with Daily Demand
