Doog's Donuts produces five varieties of pastries, which are sold to a national grocery chain: muffins, donuts, cookies, cream puffs,and fritters. Assuming that Doog's operates a single shift for 1,800 hours per year. The processing time per unit, setup time per lot, theannual demand, and lot size are given in the table. Assume that the times given are for a work cell of four workers each.a.

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?
A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used five workers, who produced an average of 80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour, while output increased by four carts per hour.A) Compute labor productivity under each system. Use carts per worker per hour as themeasure of labor productivity.B) Compute the multifactor productivity under each system. Use carts per dollar cost (laborplus equipment) as the measure.C) Comment on the changes in productivity according to the two measures, and on which one you believe is the more pertinent for this situation.
In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 11.5 hours. The time in the welding operation is spent as follows: 2 hours waiting in front of the cutting machine for the batch to start, 2 hours waiting for the setup of the machine, 1 hour waiting for the other pieces of the batch to go through cutting, 1 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 1 hour waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 0.5 hour waiting for the other pieces of the batch to go through welding, 0.5 minute at the welding machine, and 1 hour waiting for the transfer to the next department. Determine the exact flow time. What is the value-added percentage of the flow time?(round percentage answer to 4 decimal places.) answer:_______percent
Mack’s guitar fabrication shop produces low cost, highly durable guitars for beginners. Typically, out of the 100 guitars that begin production each month, only 80 percent are considered good enough to sell. The other 20 percent are scrapped due to quality problems that are identified after they have completed the production process. Each guitar sells for $300. Because some of the production process is automated, each guitar only requires 10 labor hours. Labor is paid at $10/hour, materials cost is $40/guitar, and overhead is $2,000. a) Calculate the labor and multifactor productivities. b) After some study, the operations manager recommends 3 options to improve the company’s multifactor productivity: (1) increase the sales price by 10 percent, (2) improve quality so that only 10 percent are defective, or (3) reduce labor, material, and overhead costs by 10 percent. Which option has the greatest impact on the multifactor productivity measure?

A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 5 workers, who together produced an average of 80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour while output increased by 4 carts per hour. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity.
A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 5 workers, who together produced an average of 90 carts per hour. Workers receive $13 per hour, and machine cost was $50 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $11 per hour while output increased by 5 carts per hour. a.
