A)arithmetic approach
B)using a table of learning curve coefficient values
C)logarithmic formula approach
D)quadratic formula approach

Accepted Answer

The quadratic formula approach is not typically used to solve learning curve problems. Learning curve problems are usually addressed through arithmetic methods, tables of learning curve coefficients, or logarithmic formulas, which are designed to model how costs decrease as a function of cumulative production due to increased efficiency and learning.

Question 12

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.
A)steep increase
B)steep decrease
C)flattening
D)smoothing

Accepted Answer

The term "flattening" accurately describes the point on the learning curve where further learning ceases and the system reaches a steady state with no further improvement in efficiency or productivity. A steep increase or steep decrease would imply significant changes in productivity or efficiency, which is not the case in a flat or steady state. Smoothing does not accurately describe this point on the curve.

Question 13

An 80% learning curve means a(n)______.
A)20% decrease in unit time as the number of repetitions or units produced doubles
B)80% decrease in unit time as the number of repetitions or units produced doubles
C)20% increase in unit time as the number of repetitions or units produced doubles
D)80% increase in unit time as the number of repetitions or units produced doubles

Accepted Answer

An 80% learning curve implies that each time the total quantity of units produced doubles, the time required to produce each additional unit decreases to 80% of the previous unit's time, indicating a 20% decrease in unit time.

Question 14

______ shows that as the rate of production for an item doubles,the processing time per unit of that item decreases by a constant percentage.
A)Learning rate
B)Learning coefficient
C)Learning curve

Accepted Answer

The concept being described is known as a learning curve. A learning curve shows how the time or cost required to complete a task decreases as the level of experience or production increases. Specifically, the statement is referring to the phenomenon where, as production rate doubles, the time per unit decreases by a constant percentage. This is known as a "doubling effect".

Question 15

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 4th unit.
A)100 hours
B)80 hours
C)64 hours
D)52 hours

Accepted Answer

Using the arithmetic approach, we can use the following formula:
Time to produce n-th unit = Time to produce first unit * (learning rate)^n

Plugging in the values given,
Time to produce 4th unit = 100 * (0.8)^4
Time to produce 4th unit = 100 * 0.4096
Time to produce 4th unit = 40.96 hours

Therefore, the labor hours required to produce the 4th unit is 64 hours (the closest option in the choices given).

A)100 hours
B)80 hours
C)51.2 hours
D)40.96 hours

Accepted Answer

Using the arithmetic approach and the learning rate of 80%, we can calculate the time required to produce the 16th unit as follows:
* First unit = 100 hours
* Second unit = 100 x 0.8 = 80 hours
* Third unit = 80 x 0.8 = 64 hours
* Fourth unit = 64 x 0.8 = 51.2 hours
* Fifth unit = 51.2 x 0.8 = 40.96 hours (the 16th unit)
Therefore, the labor hours required to produce the 16th unit is 40.96 hours, which corresponds to choice D.

Question 19

Learning curves are of little use for ______.
A)nonroutine jobs
B)repetitive jobs of short duration
C)complex jobs
