Question 11

On an ordinary graph,unit times for a learning curve decrease at a decreasing rate,but on a log-log graph,the learning "curve" appears as a straight line.

Accepted Answer

On a log-log graph, the learning curve is plotted as a straight line because both axes are logarithmic, which means that equal percentages of progress are shown as equal distances on the graph. As a result, the curve appears linear.

Question 14

A metal works fabricator is about to release a new model of his firm's copper sculpture and fountain.The operations manager estimates that this product is subject to a 90 percent learning curve on labor only-the material bill is not affected by experience.The firm prices its work based on cost-the sum of materials plus 30 percent and labor plus 50 percent.(This allows the firm to practice a form of "demand management" for its very popular works. )The first item has already been finished;the material bill was $800 and labor totaled 40 hours.The firm pays its metalworking artisans an average of $18 per hour.What should be the asking price of the first unit? The second?
