ANSWERSQuestion 1
The total EOQ cost is,
However, Bowen currently ordering 500 units per order. Hence, the total cost of the current order is as follows:

For Dr. Tareq’s further review
ANSWERS
Question 3
Yes, Bowen should use Kentech because they offer pump with lower price than Precision. The lower the price, the lower the carrying cost. Also, there no handling fee per order for Kentech. Bowen can save $300 per order if he use Kentech.

ANSWERS
Question 4
Bowen should order 1,000 units with the price $29 per unit. He can save up to $2440.
Option 1 Option 2
Q= 1,000 Q= 2,000
TC (28.5) –TC (29) = $6060-$3620 =$2440

Question 5
EOQ Assumptions:
• Constant or uniform demand
• Constant unit price
• Constant carrying costs
• Constant ordering cost
• Instantaneous delivery
• Independent orders
• The assumption is reasonable, because Bowen Built Inc use "make-to-stock" strategy and the item has relatively stable demand. Carrying costs and setup or ordering costs are known and relatively stable.
These assumptions have been pointed out to illustrate the limitations of the basic EOQ model and the ways in which it can be easily modified to compensate for them.

ANSWERS
Question 6
Factors besides EOQ in determining a supplier.
• Terms of credit
• Location of the supplier
• Credit worthiness of the supplier
• Warehousing facilities available with the supplier
• Size of the supplier’s firm and their product quality control

ANSWERS
Question 7
Cost Reduction by Adjusting Reorder Point:
• Perry decided to study in detail a single item, brake pumps, to help him learn more about the potential savings. Therefore, the specific item that is examined is the brake pumps.
• Annual usage of Brake Pump: 12,000 units
• Operation Time in a Year: 50 weeks
• Weekly usage of Brake Pump: 240 units
• Lead time: 2 weeks
• Reorder Point when safety stock is generously 2 weeks:
RP = (2 * 240) + 2 * 240 = 960
• Reorder point whe safety stock is trimmed into 1 week:
RP = (2 * 240) + 1* 240 = 720
• Number of orders in a year:
RP (Safety Stock 2 weeks) 12,000 / 960 = 12.5 times
RP (Safety Stock 1 week) 12,000 / 720 = 16.67 times
• Units of safety stock annually:
RP (Safety Stock 2 weeks) 12.5 * 2* 280 = 6,000 units
RP (Safety Stock 1 week) 16.67 *1* 280 = 4,000 units
• Total amount of reduction of safety stock: 6,000 – 4,000 = 2,000 units
Total cost reduction by adjusting safety stock : 2,000 units * $30 = $60,000
Cost reduction: $60,000 – ((16.67-12.5)*$300) = $58,750

ANSWERS
Question 8
Carrying Cost:
• Total cost of holding inventory over some period of time
• Short term
• Warehousing costs rent, utilities and salaries, financial costs such as opportunity cost, and inventory costs related to perishability, pilferage, shrinkage and insurance.
• Utilized to help determine how much profit can be made on current inventory
• Helps to find out if there is a need to produce more or less
Carrying cost is expected to be a short term because cost like rent, utilities, insurance, breakage is paid not in a long term basis.
Often the costs are computed for annually and then expressed as a percentage of the cost of
the inventory items [http://www.accountingcoach.com/blog/calcula
te-inventory-carrying-cost] Therefore, the figures that Perry listed includes generally all
of the carrying costs.

ANSWERS
Question 9
Change in Carrying Cost Affecting EOQ:
• Surely a change in carrying cost will affect the EOQ
• The more carrying cost needed, the lower rate of EOQ will be generated.
• Suppose the carrying cost is now 30 percent, surely this would affect the EOQ. The EOQ will be reduced by around 41% from the EOQ with the carrying cost of 20 percent
• Formula:
14
ANSWERS• However, even though a change in
carrying cost influence the overall EOQ, the change will not affect the choice of supplier in this case.
• Because the preference of supplier does not rely on the carrying cost but to the Order Cost per order.
• Carrying cost is a constant in determining such preference in this case.
• Carrying Cost is calculated as Carrying Cost percentage x Cost per unit
• So in this case, we can see the increment in Carrying cost percentage will increase the overall Carrying cost for both of the supplier.
15
ANSWERS• We can compare the
calculation of the Carrying Cost of 30 percent carrying cost percentage with the previous level of 20 percent and it will generate the ratio of 1:1.5 equally for all options.
• We can see that the preference choice depends on the Cost per unit instead of the percentage of carrying cost.
16
ANSWERS
Question 10
How a growing firm could be profitable but have cash flow problem
• Low profits or losses
• Over-investment in capacity
• Too much stock and poor inventory management
• Allowing customers too much credit
• Overtrading and growing too fast
• Seasonal demand
• Over investment in fixed assets
17
ANSWERS
Question 11
Should separate parts inventory into groups according to value?
• It is appropriate to group similar or related parts for inventory relating to the same product and for inventory that cannot be evaluated separately from other parts in that product line because it is not yet considered as finished goods

SCENARIO ANALYSIS
1. If Precision Engineering dissolve the handling fee, which supplier should Bowen choose?
𝑇𝐶 (30 )=60×12000500
+6×5002
=$2940
𝑇𝐶 (29 )=60×12,0001,000
+5.8×1,000
2=$ 3620
𝑇𝐶 (28.5 )=60×12,0002,000
+5.7×2,000
2=$6060
Bowen should choose Precision
Engineering.
