8. A firm desires to control inventory levels so as to minimize
the sum of holding and order costs. It
costs the firm $50 to place an order.
The firm estimates its inventory carrying costs at $2/unit/year. Weekly demand is 100 units, and there are 50
weeks in the work year. The item costs
$10 per unit. The lead-time for the
product is 3 weeks. Assume that there
are 5 working days per week.

consisting of 10 items. Each of these items has a unique demand pattern and may
require a different kind of inventory management system. The annual demand
pattern and the unit cost of these items are given in the following table. Classify the items in A, B, and C categories
according to annual dollar usage.

that for each completedA, 3 units ofB, 2 units ofC,
and 1 unit ofD are required. Current inventory for the four items is as
follows: There are 18As, 40Bs, 50Cs
and 35Ds in stock. If the lead time for all items is one week and
there are no scheduled receipts for any item, how many units of productA
can be delivered to customers at the start of next week (week 2)?
