Textbook Question
Chapter 5, Problem 8P
A manager is trying to decide whether to purchase a certain part or to have it produced internally. Internal production could use either of two processes. One would entail a variable cost of $17 per unit and an annual fixed cost of $200,000; the other would entail a variable cost of $14 per unit and an annual fixed cost of $240,000. Three vendors are willing to provide the part. Vendor A has a price of $20 per unit for any volune up to 30,000 units. Vendor B has a price of $22 per unit for demand of 1,000 units or less, and $18 per unit for larger quantities. Vendor C offers a price of $21 per unit for the first 1,000 units, and $19 per unit for additional units.

At Fraser engineering. Erix is trying to decide whether to purchase a certain part to to have it produced internally. Internal production could use either of two processes. One would entail a variable cost per unit of $17, and an annual fixed cost of $240,000. Three vendors are willing to provide the part.
Vendor A has a price of $20 per-unit for any volume up to 30,000 units
Vendor B has a price of $22 per-unit for demand of 1,000 units or less, and $18 per-unit for larger quantities.
Vendor C offers a price of $21 per-unit for the first 1,000 units, and $19 for each additional unit.
What is the correct formula to use to compare these options?
Which options would be best for:
I. 10,000 units?
ii. 20,000 units?
iii. 100,000 units?
What is the value in considering these options across three very different demand values ranging from 10,000 to 100,000 units?
snip
You are in charge of a large assembly shop that specializes in contract assignments. One of your customers has promised to award you a large contract for the assembly of 1,000 units of a new product. The suggested bid price in the contract is based on an average of 20 hours of direct labor per unit. You conduct a couple of test assemblies and find that, although the first unit took 50 hours, the second unit could be completed in just 40 hours. a. How many hours do you expect the assembly of the third unit to take? b. How many hours do you expect the assembly of the 100th unit to take? c. Is the contract’s assumption about the average labor hours per unit valid or should the price be revised?

Given the increase in annual requirement, the production manager is contemplating to start manufacturing the special components in-house to save costs rather than sourcing them from outside. Given the current purchase price of $9000 per unit, what will the average annual requirement need to be in order to justify making the components in-house if the variable cost of making is $6750 per unit and an upfront fixed cost of $55,000,000 is needed to procure the necessary plant and equipment? However, in the event that the expected increase in demand does not materialize and the demand is actually forecast to drop to 20,000 units next year, then what will be the maximum price per unit that DBS would be willing to pay to the supplier in order to continue buying from them?
