The number of kanbans that should circulate between two workstations is 5.
Given:
Demand=500
Lead time=20
Container size=35
Safety factor=5
Hence:
Number of kanbans=[(500×0.33) +(0.05×500)×.33)]/35
Number of kanbans=165+8.25/35
Number of kanbans=173.25
Number of kanbans=4.95
Number of kanbans=5 (Approximately)
