a)
To determine: The time taken for the second return.
Introduction:
Learning curve:
Learning curve is based on the premise that when a person is repeating a task or job again and again, the performance of the person on that job or task will improve. It will depict relationship between cost and output over a definitive period of time.
b)
To determine: The time taken for the fourth return.
Introduction:
Learning curve:
Learning curve is based on the premise that when a person is repeating a task or job again and again, the performance of the person on that job or task will improve. It will depict relationship between cost and output over a definitive period of time.
c)
To determine: The time taken for the eighth return.
Introduction:
Learning curve:
Learning curve is based on the premise that when a person is repeating a task or job again and again, the performance of the person on that job or task will improve. It will depict relationship between cost and output over a definitive period of time.

- You are asked to do a learning curve analysis as part of your internship project, but you discover that the data is pretty slim. Unfortunately you don't have time to do more field work and you have to come up with the best estimate based on the available data. Here's what you know: It took 98.71 minutes to complete the seventh unit and only 89.35 minutes to complete the twelfth unit. What is your best estimate of the Learning Rate for this process?arrow_forwardFor an 80% learning curve, if the 100th unit produced required 280 hours, how long will it take to produce the 400th unit? Show your calculations.arrow_forwardBeth Zion Hospital has received initial certification from the state of California to become a center for liver transplants. The hospital, however, must complete its first 18 transplants under great scrutiny and at no cost to the patients. The very first transplant, just completed, required 28 hours. On the basis of research at the hospital, Beth Zion estimates that it will have an 75% learning curve. Using Table E.3, estimate the time it will take to complete: Unit number 5 75% Unit time: .513 Total time: 3.459 80% Unit number 5 Unit time: .596 Total time: 3.738 85% Unit number 5 Unit time: .686 Total time: 4.031 Unit number 18 75% Unit time: .301 Total time: .8.245 Unit number 18 80% Unit time: 3.94 Total Time: 9.716 Unit number 18 85% Unit time: .508 Total time: 11.405 a) the 5th transplant = 14.36 hours b) the first 5 transplant = ? hours (round your response to two decimal places)arrow_forward
- If a company is preparing a bid on a government contract for 40 units of a certain product. The operations manager estimates the assembly time required for the first two units to be 10.4 hours and 8.8 hours respectively. What is the appropriate learning curve? Explain and show your answer.arrow_forwardLucid Inc. has developed a cutting-edge medical device. It took the company 500 hours to build the first device. The company uses an 87% learning rate for this task. How long should it take the company to build the 24th device? the 76th device? the 128th device?arrow_forwardMaxera Corporation has designed a new video game controller. It took the company 52 minutes to produce the first unit. If the company uses a 75% learning rate for this task, how long should it take the company to produce the 6th unit? the 18th unit? the 30th unit? the first 6 units? the first 18 units? the first 30 units? the units 7th through 18th? the units 19th through 30th?arrow_forward
- Use learning curve theory to predict the number of repetitions (units) that will be neededfor a trainee to achieve a unit time of 6 minutes if the trainee took 10 minutes to do the firstunit and a learning curve of 90 percent is operative.a. Use the learning table.b. Use the log formula.arrow_forwardThe fifth unit of a 25-unit job took 14.5 hours to complete. If a 90 percent learning curve is appropriate:a. How long should it take to complete the last unit?b. How long should it take to complete the 10th unit?c. Estimate the average time per unit for the 25 units.arrow_forwardAqeel bought 6 bookcases for his place. Each required unpacking of parts and assembly, which included some nailing and bolting. Aqeel completed the first bookcase in 5 hours and the second in 4 hours. 1-What is his learning rate (k)? 2-What is his learning-curve value of b? 3-Assuming that the same rate continues, how long will the 3rd, 4th, 5th, and 6th bookcases take? Y3 = hours Y4 = hours Y5 = hours Y6 = hours 5-How long will take him to finish all the 6 cases? It will take him hours.arrow_forward
- If it took 410 hours to produce the first unit of a product, and the learning curve is 90%, how long will it take to produce units 12 through 25???arrow_forwardA contractor is preparing a bid to install swimming pools at a new housing addition. The estimated time to build the first pool is 33 hours. The contractor estimates an 80 percent learning rate. Using POM for Windows or OM Explorer, how long do you estimate the time required to install the fifth pool?arrow_forwardIf the first unit of a product took 25 minutes to produce and the learning curve rate is 80%, how much time will the production of the 100th unit take?arrow_forward
