Suppose we have an EOQ inventory system as follows:
 Order quantity = 600 units/order
 Daily demand = 40 units/day Order lead time = 5 days.
Suppose at the beginning of day 1, there are 600 units ininventory and there is no outstanding order.
In order to avoid shortage, a new replenishment order must
be placed at the end of what day? Why?
I need answer now.
