2) (25 points) Consider three items with the following demand profiles: Item Annual Demand A B 100 units 50 units 200 units Annual Requests 25 requests 5 requests 16 requests Unit Cube 1 ft 0.5 ft? 2 ft? a) What is the total annual demand in cubic feet for items A, B, and C? b) If 20 ft of space is allocated for storing item C, how many times will the item be replenished in one year? c) If each item is to receive a location in the forward area and an equal-time-supply allocation policy is used, how much space will be allocated for each item assuming a one- week time supply? Assume a year has 50 weeks. d) If the items are to be assigned locations in the forward area on the basis of popularity and they are allocated space as in part c, rank the items so as to maximize the number of picks in the most accessible storage space
