Question

A workstation must produce 200 units an hour. It takes 45 minutes to receive the necessary material for production from the previous workstation. Output is moved between workstations in containers holding 30 units. If the process uses a safety factor of 20%, then the number of kanbans that should be circulating between this workstation and the previous workstation is: Group of answer choices

Answer 1

The number of Kanbans circulating between this workstation and the previous workstation is 6 Containers

Step-by-step explanation:

Given demand = 200 unit / hour

45 minutes between one workstation to another

Container size = 30

Safety factor = 20% = 0.2

Demand during lead time of 45 minutes = 45minute / 60minute * 200 units = 150 units

Number of Kanbans = Demand during lead time ( 1 + Safety factor) / Container size

= 150 (1 + 0.20) / 30

= 150 (1.20) / 30

= 180 / 30

= 6 Containers
