PSH Industries uses a Kanab system to manage production of the J-l5 subassembly, hey have an hourly demand for 250 units and use containers that can hold 50 units each. It takes 90 minutes to fill and move a container of parts to the right place on the MS line that is currently rated at a 20% safety factor. How many production cards are needed? 540 100 9 1.5
Expert Answer
hourly Demand=250
Lead time=90 mins=90/60=1.5 hrs
Kanban size=50
Number of Kanbans(production cards)=?
Safety factor=20%
Number of Kanban = (average demand during lead time + safety stock) / container quantity
=(250*1.5+250*1.5*20%)/50=(450/50)=9
option (c) is the answer
