The first unit of a product took 832 hours to build,and the learning curve is 90%.How long will it take to make the 25th unit? (Use at least three decimals in the exponent if you use the formula approach. )

________ are based on the premise that people and organizations get better at their tasks as the tasks are repeated.

The learning-curve table approach may be simpler to use than the formula approach,but it requires the presence of a table of learning-curve coefficients.

An 80% learning curve means that with each unit increase in production,labor requirements fall by 20%.

Learning curves have a variety of purposes.Your text places them into which three broad categories?

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 8.3 hours,respectively. a.What is the appropriate learning curve? b.What is the average time per unit for the 40 units? c.Which unit,if any,will require approximately one-half the time of the first unit?

The first unit of production took 10 hours with an 80% learning curve.How long will it take to complete both the first and second units?

The doubling approach to learning curve calculations allows us to determine the hours required for any unit.

The fourth unit of production took 80 minutes while the ninth unit of production took 50 minutes.How long did the first unit take?

The first unit took 10 hours and the eighth unit took 1.25 hours.What is the learning curve?

A project manager bases his time and labor estimates on a learning curve of 86%.The actual learning curve turns out to be 89%.The manager,because of the decreased learning,will complete his project in more time and with more labor use than his estimate suggested.

To use the table of learning-curve coefficients,you must specify ________ and ________.

The first unit of a product took 50 hours to build,and the learning curve is 85%.How long will it take to make the 10th unit? (Use at least three decimals in the exponent if you use the formula approach. )

In addition to labor,to which other variables have learning curves been applied?

A firm that successfully pursues a steeper-than-industry-average learning curve and manages costs down may still fail if,by underestimating a strong competitor,it fails to gain the added volume necessary for the learning curve to exist.

The fundamental premise underlying learning curve analysis is that:

A job with a 90% learning curve required 20 hours for the initial unit.The fourth unit should require approximately how many hours?

The first unit took 79 hours;the tenth took 46 hours.What learning curve is implied by the data?
