Exam 25: Learning Curves

In the Learning-Curve Coefficients table for 70% learning,the sixth unit has a unit time value of 0.398.Verify that table entry by use of the logarithmic formula.Use five decimals in your work.

The earliest application of learning curves appears in the work of architect Frank Lloyd Wright.

The fundamental premise underlying learning curve analysis is that

"By tradition,learning rates are defined in terms of the complements of their improvement rates." Explain.

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.

In the logarithmic approach to learning curve calculations,you have used the formula TN = T1.(Nb).For a problem with a 92% learning rate,what is b?

A contractor builds large ships for the Department of Defence.A recent contract called for 12 amphibious landing platforms.It was originally estimated that the first of these would cost $1 billion and that 80% learning would be appropriate.In fact,the first ship cost $1.6 billion and the second $1.12 billion.What is the revised learning rate? What will be the total cost of the twelve ships? Is it higher or lower than the original estimates? If the defence department cuts the contract from 12 ships to 9,what happens to the average cost per ship?

Learning curves are

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

Explain how learning curves might be applied in a scheduling application.

Which of the following is false regarding learning curves?

What is the basic premise underlying the learning curve?

Which one of the following statements about learning curves is true?

A small manufacturer builds wooden pleasure boats in a craftsman manner by traditional labour-intensive methods.The first boat is estimated to take 650 hours of skilled labour,which cost $40 per hour.They currently have three workers that can work 2,000 hours a year.They assume that there is a 90% learning rate.How many boats can they make in their first year?

Your company is making experimental turbochargers for a new design of high-powered farm tractors.The production schedule for these new components is contained in the table below. The first turbocharger,a trial unit,took 900 hours to produce.Based on your experience with similar products,the learning factor is 85%.You have 20 employees,and each employee works 160 hours per month.How many hours will be required in each month? In which month(s)will overtime be required to meet the production schedule?

The second unit of production took 9 hours.If the learning curve is 90% how long did the first unit take?

The learning curve for a product is 80%.The first unit took 100 hours to complete.The manufacturer wants to determine how many hours the fifth unit will take by using the logarithmic method.The coefficient b for that calculation is approximately

If the first unit in a series of units takes 200 days to complete,and the learning curve is 80%,then the second unit will take 160 days.

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

The arithmetic approach (or successive doubling approach)to learning curve calculations allows us to determine the hours required for any unit.
