Exam 6: Learning Curves

A company can produce a small lot of products the first time at a cost of $2,000. If their 85 percent learning curve allows them to reduce their costs on each lot, what is the total cost of producing 5 lots?

You have just timed a person doing a job four times. The first time it took the person 120 minutes, the second time it took 90 minutes, the third time it took 76.1 minutes, and the fourth time it took 67.5 minutes. Which learning curve unit improvement factor should you use?

With an 80 percent unit improvement factor learning curve and an initial time of 100 minutes to do a job, at what number of repetitions will the job take less than 50 minutes?

The 50^th repetition of a job is timed at 100 minutes. If the learning curve for this job is 90 percent, what is the estimated time for the 200^th repetition of this job?

A company can produce a small lot of products the first time at a cost of $3,000. If their 65 percent learning curve allows them to reduce their costs on each lot, what is the cost of producing the 12^th lot?

If a person performing a task has been achieving an 80 percent learning curve and it took 10 minutes to produce the first unit, the total time to produce 100 units will be 326.5 minutes.

You time someone completing a single task the first time at 10 minutes, and the second time they do the task it takes 9 minutes. You should use an 80 percent learning curve to estimate the length of time this worker will take to complete this task in the future.

You have determined that a 60 percent learning curve is appropriate for a task. If your initial timing of person performing that task was 35 minutes and if you need the task performed 1,000 times, how many minutes of work will be required?

You time someone completing a single task the first time at 100 minutes, and the fourth time they do the task it takes 81 minutes. You should use a 90 percent learning curve to estimate the length of time this worker will take to complete this task in the future.

Economies of scale and the learning curve have opposite effects on capacity.

A learning curve shows the decrease in time required for each successive unit completed.

A company can produce a small lot of products the first time at a cost of $3,000. If their 65 percent learning curve allows them to reduce their costs on each lot, what is the cost of producing the 20^th lot?

Highly automated systems may have a near-zero learning curve.

You are a consultant called in to estimate the costs after the employees learn how to do a job more efficiently by repetition of new product. You find a company can produce a product the first time at a cost of $5,000. If their 90 percent learning curve allows them to reduce their costs on each unit, what is the total cost of producing 100 units of the new product?

The 50^th repetition of a job is timed at 100 minutes. If the learning curve for this job is 90 percent, what is the estimated time for the 100^th repetition of this job?

A company's production process has an 85 percent learning curve rate. The process has produced 1,000 units to date. A process refinement is estimated to allow a future learning curve rate for the identical product of 75 percent. However, the initial unit made using the new process will take the same amount of time as the very first unit produced using the old process. At what point, using the new process, will the production rate exceed the production rate achieved by the old process?

The 10^th repetition of job is timed at 100 minutes. If the learning curve for this job is 80 percent, what is the estimated time for the 100^th repetition of this job?

Which of the following computational methods are used to calculate learning curve statistics?

The unit improvement factor for a 60 percent learning curve at 25 units is 0.0933. The first and second timings of a person doing a job are 10 minutes and 6 minutes, respectively. The learning-adjusted time estimate for the unit number 25 is 0.9330 minute.
