Exam 25: Learning Curves

Suppose that there are two products with the same first product time. However, product A has an improvement rate of 10% while product B has an improvement rate of 20%. How much longer will it take to make the 10ᵗʰ unit of product A compared to product B?

Which of the following is not a limitation of the use of learning curves?

What cautions are in order when using learning curves?

The first product took 10 hours to build and the learning curve is estimated to be 90%. How long with it take to make the fourth unit?

If it took 1000 hours to produce the first unit of a product, and the learning curve is 70%, how long will it take to produce units 26 through 50?

What is the basic premise underlying the learning curve?

When comparing a 70% learning curve versus a 90% learning curve, which one results in a more rapid reduction in labor requirements? Why?

You are about to undertake manufacture of a labor-intensive electronics component. The first unit took 300 hours. You are not sure whether the learning rate is 70% or 80%. The initial phase of the contract calls for 6 of these components. a. How much time will it take to complete all six at 70% learning? b. How much time will it take to complete all six at 80% learning?

If the learning curve for a process is 100 percent, then each unit in a series of units will have the same labor requirements.

Which of the following is representative of a firm pursuing a learning curve strategy?

The seventh unit of production took 63.423 minutes while the ninth unit of production took 59.8 minutes. What is the improvement rate?

The first unit of a product took 832 hours to build, and the learning curve is 75%. How long will it take to make the 30th unit? (Use at least three decimals in the exponent if you use the logarithmic approach.)

Learning curves can only be applied to labor.

Failure to consider the effects of learning can lead to __________ of labor needs.

A 90% learning curve implies that each time the production volume is doubled the direct time per unit is reduced to 90% of its previous value.

In the logarithmic approach formula to compute the time for the Nth unit, TN = T₁Nᵇ, the exponent b is the learning curve rate L, expressed as a decimal.

The first unit of a product took 900 hours to build and the learning curve is 90%. How long will it take to make the first 3 units?

Which of the following statements regarding the usefulness of learning curves is False?

The fact that human activities typically improve when they are done on a repetitive basis is described by a

Using the arithmetic concept determine how long it will take to make the 64ᵗʰ unit of a product if it took 1 hour to complete the first product with a 50% learning rate.
