9. The Ace Manufacturing Company has orders for three similar products: Orders Product (units) A 2000 500 1200 B C Three machines are available for the manufacturing operations. All three machines can produce all the products at the same production rate. However, due to varying defect per- centages of each product on each machine, the unit costs of the products vary depending on the machine used. Machine capacities for the next week and the unit costs are as follows: Сараcity (units) Product Machine Machine A в C 1500 $1.00 $1.30 $1.10 $1.20 $1.40 $1.00 $0.90 $1.20 $1.20 1 1500 1000 3 Use the transportation model to develop the minimum cost production schedule for the products and machines.

A toy firm produces drums sequentially on three machines- A, B, and C- with cycle times of three, four, and six minutes, respectively. a) Determine the optimum efficiency and output rates for adding one, two... six more machines b) Assume now that two identical lines are operating, each with machines A, B, and C. If new machines can be shared between the lines, how should one, two, and then three new machines be added? What are the resulting efficiencies and outputs of the two lines? Is it always best to equally share extra machines between the two lines?

Why is the Hayes and Wheelwright product-process matrix NOT used to analyze service delivery systems? a. The relationship between volume and process is not found in many service businesses. b. Services tend to have lower variety, so the variety element of Hayes & Wheelwright is not applicable. c. Services cannot add capacity. d. When services change processes to increase volume, they can still handle a wide variety of customer requests.

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?
