Question 1
A company has the option of purchasing or manufacturing an item. If the
item is purchased, the company will be charged $25 per unit plus $4 per
order. If the company manufactures the item, it has a production capacity
of 8,000 units per year. It costs $50 to set up a production run, and annual
demand is 3,000 units per year. If the annual holding cost is 10% and the
cost of manufacturing one unit is $23, determine whether the company
should purchase or manufacture the item.
Question 2
The Simple Simon Bakery produces family-size pies for freezing and
subsequent sale. The bakery operates 5 days a week, 52 weeks a year and
can produce 62 pies per day. The bakery sets up the pie production
operation and produces until a predetermined number (Q) has been
produced. When not producing pies, the bakery uses its personnel and
facilities for producing other items. The setup cost for a production run of
pies is $500. The cost of holding frozen pies in storage is $5.50 per pie per
year. The annual demand for frozen pies, which is constant over time, is
6,000 pies.
Determine the following:
(a) The optimal production run quantity (Q).
(b) The total annual inventory costs.
(c) The optimal number of production runs per year.
(d) The optimal cycle time (time between run starts).
(e) The run length (in working days).
Question 3
The King Olaf Bar buys Old World draft beer by the barrel from a local
distributor. The bar has an annual demand of 900 barrels, which it
purchases at a cost of $205 per barrel. The annual carrying cost is 12% of
the price, and the cost per order is $160. The distributor has offered the
bar a reduced price of $190 per barrel if it will order a minimum of 300
barrels. Should the bar take the discount and if so, what type of saving will
they reap? Show your work.
