GUARANTEED PASS
The optimal utilization rate of a service operation is context specific. Planning for low
utilization rates is appropriate when both the degree of uncertainty and the stakes are
high as in emergency response services. Which of the following services should plan for
a high utilization rate?
A. An expensive restaurant
B. The fire department
C. A hospital ambulance service
D. A customer help line
E. A stage performance - Answers -E. Stage performance
(All sports teams like sellouts, not only because of the virtually 100 percent contribution
margin of each customer, but because a full house creates an atmosphere that pleases
customers, motivates the home team to perform better, and boosts future ticket sales.
Stage performances share this phenomenon.)
The point at which the scale economy curve and the learning curve intersect is called
the capacity optimum.
T/F - Answers -FALSE
(Capacity optimum is a meaningless term not referenced in the text.)
The unit improvement factor for a 60% learning curve at 25 units is 0.0933. The first and
second timings of a person doing a job are 10 minutes and 6 minutes respectively. The
learning-adjusted time estimate for the unit number 25 is 0.9330 minutes.
T/F - Answers -Learning curve rate = 60% = 0.6
Unit improvement factor at 25 units = 0.0933
Time required for 1st unit = 10 minutes
The unit time for the nth unit can be calculated using learning curve formula as follows:
Tn = T1 x C
,T1 = time required for first unit
Tn = time required for nth unit
C = unit improvement factor
T25 = T1 x C = 10 x 0.0933 = 0.9330 minute
TRUE
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 - Answers -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 - Answers -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 - Answers -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 - Answers -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.
T/F - Answers -TRUE
In solving a tree problem, we work from the end of the tree backward to the start of the
tree.
The capacity cushion is the ratio of capacity used to the best capacity level.
T/F - Answers -FALSE
