GRADED A+
You time someone completing a single task the first
time at 120 minutes and the second time they do the
task it takes 108 minutes. You should use a 90 percent
Learning Curve to estimate the length of time this
worker will take to complete this task in the future.
T/F
T1 = time required for first unit = 120 minutes
T2 = time required for 2nd unit = 108 minutes
Tn = time required for nth unit
Learning rate from 1st to 2nd unit = Time required for
2nd unit/time required for 1st unit = L2/ L1
T2/ T1 = 108/120 = 0.90
TRUE

,A production facility develops virtuosity and works best
when it focused on a widely varied set of production
objectives.
Group of answer choices
T/F
FALSE
(A production facility works best when it focuses on a
fairly limited set of production objectives.)
Overtime and personnel transfers are solutions to
capacity problems in the intermediate term.
T/F
FALSE
(Short range —less than one month. This is tied into the
daily or weekly scheduling process and involves
making adjustments to eliminate the variance between
planned and actual output. This includes alternatives

,such as overtime, personnel transfers, and alternative
production routings)
A company's production process has an 80 percent
learning curve rate. The process has produced 1,000
units to date. A process refinement is estimated to
allow a future learning curve rate for the identical
product of 75 percent. However, the initial unit made
using the new process will take the same amount of
time as the initial unit produced using the old process.
At what point, using the new process, will the
production rate exceed the production rate achieved by
the old process?
A. Before the 250th unit
B. Before the 100th unit
C. Before the 120th unit
D. Before the 80th unit
E. Before the 50th unit
T = aNb

, Where T= time to produce Nth units
a= time to produce first unit
b=slope=Log(learning rate)/log2
We need our answer to be less than the decimal we get
from 1000^(log0.8)/log2)
So 1000^(log0.8/log2) = 0.108917
Then N^(log0.75/log2) < =0.108197
So we plug our N from all the answers until we get a
decimal smaller than for our answer above
at N=250 250^(log0.75/log2)=0.101103 which is <=0.108197
In solving a decision tree problem, calculations start at
the ends of the "branches" of the tree and work
backwards to the base of the tree.
