If the tenth unit produced took 24 hours and the fifth unit took 32 hours, answer the following. a) What is the learning rate? b) How long did the first unit take to complete? c) How long did the third unit take to complete?
Given time taken for 10th unit = 24 hours
T10 = T*(10)^b
Where b = ln(P) /ln(2)
And T is the time taken to produce 1st unit
Where P is the learning rate.
Similarly time taken for 5th unit = 32 hours
T5 = T*(5)^b
Dividing T10 and T5
24/32 = 10^b/5^b
2^b = 0.75
b = ln(0.75)/ln(2)
ln(p)/ln(2) = ln(0.75)/ln(2)
Therefore P = 0.75
Question A. Learning rate = 0.75 or 75%
b = - 0.415
T = T10 / (10^b)
= 24/(10^-0.415)
= 62.40
Question B. It takes 62.40 hours to produce first unit.
Question C.
T3 = T*(3^b)
= 62.40* (3^-0.415)
= 39. 55
So it takes 39.55 hours to produce 3rd unit

It took MegaTech, Inc. 200,000 labor-hours to produce the first of several oil drilling rigs for Antarctic exploration. Your company, Natural Resources, Inc. has agreed to purchase the fifth oil drilling rig from their manufacturing yard. Assume that MegaTech experiences a learning rate of 75%. At a labor rate of $38 per hour, what should you, as the purchasing agent expect to pay for the fifth unit? TN = T1C, Where TN = Time needed to produce the Nth unit...
