decreases. Ans: all three options
Queuing system A has a utilization of 80 percent, and queuing system B
has a utilization of 90 percent. Both have a single server. Say the
utilization of both systems increases by 5 percent; that is, A increases
from 80 percent to 85 percent while B increases from 90 percent to 95
percent. Which system is likely to experience the bigger change in the
average time in queue? Ans: System B
system A; utilization = 80% -> 85%
system B; utilization = 90% -> 95%
, 3 for specific request mail
Time in queue increases at a faster rate as the utilization increases.

number of customers in a queuing system (y-axis) over a long period of
time (x-axis). Which of the following is most likely a stable system? Ans:
The one that's most linear is the stable queue system
Which of the following best reflects pooling capacity to reduce restroom
queue lengths? Ans: Convert the separate men's and women's rooms into

country). Which single suggestion in the following list (and explanation)
is most likely to reduce the average time callers wait before speaking
with a nurse? Ans: Instead of using callers' zip codes, route calls to the
2026
call center with the fewest callers to help prevent situations in which
