Store is open 7 days/week. orders units every other week. maintains safety stock of 120 units. weekly sales is 800 units. lead time is 3 days. current inventory is 350 units, how many units should it order?
Weekly sales = 800 units
As the units are ordered every other week, the total sales in 2 weeks period = 2*800 = 1600 units
Current inventory = 350 units
Safety stock to be maintained = 120 units
Thus, the number of units to be ordered = Total demand - current inventory + safety stock + lead time*sales per day
= 1600 - 350 + 120 + 3*(800/7) = 1713 units
