A.J.’s Wildlife Emporium manufactures two unique birdfeed-ers (Deluxe and Super Duper) that are manufactured andassembled in up to three different workstations (X, Y, Z) us-ing a small batch process. Each of the products is producedaccording to the flowchart in Figure 5.14. Additionally, theflowchart indicates each product’s price, weekly demand,and processing times per unit. Batch setup times are neg-ligible. A.J. can make and sell up to the limit of its weeklydemand and there are no penalties for not being able to meetall of the demand. Each workstation is staffed by a workerwho is dedicated to work on that workstation alone and ispaid $16 per hour. The plant operates 40 hours per week,with no overtime. Overhead costs are $2,000 per week. Basedon the information provided, as well as the information con-tained in the flowchart, answer the following questions.a. Using the traditional method, which bases decisionssolely on a product’s contribution to profits and over-head, what is the…

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.

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.
