Exam 28: Learning Curves

Purple Airlines has ordered 30 small jets from its supplier.The supplier has estimated the first aircraft will require 350 days of direct labor to manufacture and assemble.Based on past experience,the supplier estimates the learning curve to be 75%.Estimate the number of days of direct labor for the 15th jet aircraft.

Acme,Inc.,produces widgets.To manufacture a new type of widget,it took 50 hours for the first widget.Acme estimates it has an 85% learning rate.Using the logarithmic approach,calculate the time it will take to manufacture the 50th widget.

Purple Airlines has ordered 30 small jets from its supplier.The supplier has estimated the first aircraft will require 350 days of direct labor to manufacture and assemble.Based on past experience,the supplier estimates the learning curve to be 75%.Estimate the average number of days of direct labor for all 30 jet aircrafts.

Weston,Inc.,produces widgets.To manufacture a new type of widget,it took 21 iterations before the process reached a steady state of 39 hours.If Weston has an 87% learning rate,use the logarithmic approach to calculate the time it took to manufacture the first widget.

Typically,when an activity is performed repeatedly,the time required to perform it steadily decreases.Which of the following captures this phenomenon?

Weston,Inc.,produces widgets.To manufacture a new type of widget,it took 24 iterations before the process reached a steady state of 14 hours.If Weston has a 95% learning rate,use the logarithmic approach to calculate the time it took to manufacture the first widget.

Compared to other industries,learning curves can be more challenging to apply in ______.

Acme,Inc.,produces widgets.To manufacture a new type of widget,it took 64 hours for the first widget.Acme estimates it has an 87% learning rate.Using the logarithmic approach,calculate the time it will take to manufacture the 62th widget.

Acme,Inc.,produces widgets.To manufacture a new type of widget,it took 45 hours for the first widget.Acme estimates it has a 92% learning rate.Using the logarithmic approach,calculate the time it will take to manufacture the 22nd widget.

Acme,Inc.,produces widgets.To manufacture a new type of widget,it took 25 hours for the first widget.Acme estimates it has a 98% learning rate.Using the logarithmic approach,calculate the time it will take to manufacture the 100th widget.

Weston,Inc.,produces widgets.To manufacture a new type of widget,it took 21 iterations before the process reached a steady state of 47 hours.If Weston has an 87% learning rate,use the logarithmic approach to calculate the time it took to manufacture the first widget.

Weston,Inc.,produces widgets.To manufacture a new type of widget,it took 13 iterations before the process reached a steady state of 39 hours.If Weston has a 99% learning rate,use the logarithmic approach to calculate the time it took to manufacture the first widget.

Learning curve effects enable managers to pursue aggressive pricing strategies to penetrate new markets and still be profitable in the long run.This statement is an application of learning curves in which of the following functions?

The first unit produced in a process takes 600 hours.As the number of units produced doubles,production time decreases by 32%.Using the arithmetic approach,calculate the production time for the 128th unit.

Learning curves were first applied to the aircraft industry in ______.

Weston,Inc.,produces widgets.To manufacture a new type of widget,it took 15 iterations before the process reached a steady state of 35 hours.If Weston has an 82% learning rate,use the logarithmic approach to calculate the time it took to manufacture the first widget.

The first unit produced in a process takes 400 hours.As the number of units produced doubles,production time decreases by 20%.Using the arithmetic approach,calculate the production time for the 64th unit.

After a certain point,no further learning occurs,and each subsequent repetition or unit produced take the same amount of time,and the system has reached a steady state.This is illustrated by the ______ of the learning curve.

Assume that it takes 100 hours to produce the first unit of a product,and the learning rate for this production process is 80%.Using the arithmetic approach,determine the labor hours required to produce the 16th unit.

Which of the following metrics is used to calculate the cumulative or total time required to complete a given number of repetitions of a task or produce a given number of unit of an item?
