Kanban Problem You have just graduated from Baruch and your new employer has asked you to set up an inventory control system using a kanban control system using containers. You know from historical records that the average demand rate for your companys product, d-bar (units/time), is 200 units/day, the lead time for a replenishment order, L (time), is 4 days, and the Economic Order Quantity is 20 units. If you decide that you want to have a safety stock SS (percent of expected demand during lead time) of 10%, then how many kanbans (containers) will you need?
