Concept explainers
a)
To estimate: The amount of time needed to complete the fifth plane.
Introduction: Learning curve is referred as the cost curve, experience curve, efficiency curve or productivity curve. The leaving curve gives information about the cost, efficiency, productivity and performance of an organization.
b)
To estimate: The amount of time needed to complete first five planes.
Introduction: Learning curve is referred as the cost curve, experience curve, efficiency curve or productivity curve. The leaving curve gives information about the cost, efficiency, productivity and performance of an organization.
c)
To estimate: The amount of time needed to complete all 18 planes.
Introduction: Learning curve is referred as the cost curve, experience curve, efficiency curve or productivity curve. The leaving curve gives information about the cost, efficiency, productivity and performance of an organization.

- A manager wants to estimate the remaining time that will be needed to complete a five-unit job. The initial unit of the job required 12 hours, and the work has a learning percentage of 77. Estimate the total time remaining to complete the job.arrow_forwardA job is known to have a learning percentage equal to 82. If the first unit had a completion time of20 hours, estimate the times that will be needed to complete the third and fourth units.arrow_forwardSuppose a manufacturer of copiers has concluded that a 70 percent learning curve applies to the time a beginning service technician takes to install copy machines. Use the Learning Curve Excel template to answer the following questions: If the time required to install the first copy machine is estimated to be five hours, what is an estimate of the time required by a new technician to install the second and third copiers? Round your answers to one decimal place. For x = 2 it takes hours For x = 3 it takes hours If the learning rate changes to 65 or 95 percent, what is an estimate of the time required by a new technician to install the second and third copiers? Round your answers to one decimal place. For x = 2 and a 65% LC, it takes hours For x = 3 and a 65% LC, it takes hours For x = 2 and a 95% LC, it takes hours For x = 3 and a 95% LC, it takes hoursarrow_forward
- It takes Boeing 29,454 hours to produce the fifth 787 jet. The learning factor is 80%. Time required for the production of the twelfth 787: 12th unit time:arrow_forwardOmega Technology is starting production of a new supercomputer for use in large research universities. It has just completed the i rst unit, which took 120 labor hours to produce. Based on its experience, it estimates its learning percentage to be 80 percent. How many labor hours should it expect the second unit to require to manufacture?arrow_forwardOmega Technology is starting production of a new supercomputer for use in large research universities It has just completed the first unit, which took 120 labor hours to produce.

- A contractor is preparing a bid to install swimming pools at a new housing addition. The estimated time to build the first pool is 21 hours. The contractor estimates a 90 percent learning rate. Part 2 a. How long do you estimate the time required to install the second pool? enter your response here hours. (Enter your response rounded to two decimal places.) Part 3 b. How long do you estimate the time required to install the fourth pool? enter your response here hours. (Enter your response rounded to two decimal places.)arrow_forwardAn activity is known to have an 80 percent learning curve. It has taken a worker 10 hoursto produce the first unit. Determine expected completion times for these units: the 2nd, 4th,8th, and 16th (note successive doubling in the unit column).arrow_forwardOmega Technology is starting production of a new supercomputer for use in large research universities. It has just completed the first unit, which took 120 labor hours to produce. Based on its experience, it estimates its learning percentage to be 80 percent. How many labor hours should it expect in manufacturing the second unit?arrow_forward
- The 4th unit of a 10-unit job took seven hours to complete. The 6th unit has been worked on for two hours, but is not yet finished. Estimate the additional amount of time needed to finish the 6th unit if the work has a 65% learning curve slope O a. 6.143 hours O b. 5.114 hours O c. 3.441 hours O d. 3.058 hours O e. 4.143 hoursarrow_forwardIf 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_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
