Questions
A customer enters a business and joins the one line that snakes back and forth through the
lobby in order to receive service. The initial part of the service is performed by one customer
service representative, after which the customer enters a second, shorter line to complete the
service before leaving the establishment. Which description of this waiting line system is
appropriate? - ✔✔multiple channel/single phase
Customer arrivals at a dry cleaning service occur randomly throughout the day. The distribution
that is usually used to model the interval between arrivals is the: - ✔✔Poisson Distribution
The bank manager of a busy downtown location found herself unable to find good teller help so
she invested in an ATM to handle the routine withdrawals that tended to occupy an inordinate
amount of the teller's time. Before she installed the ATM she found that customers were
arriving on average every 2 minutes (Poisson distributed) and it took a teller 30 seconds
(exponentially distributed) to process their request. The ATM is able to maintain a constant 30
second service time. What is the impact on system utilization? - ✔✔there is no change
One advantage of simulation modeling is: - ✔✔It allows the user to conduct a "what if"
analysis
4) Which of the following statements about simulation is BEST? - ✔✔Simulation permits
managers to test the effects of new policies and procedures without disrupting customer
service.
Which of the following is characteristic of Monte Carlo simulation? - ✔✔statistical sampling is
used to create outcomes for many trials
Each outcome of flipping a fair coin is completely independent of the previous flip. This
outcome is known as: - ✔✔memory less
