1. How does adding an additional server change the value of W in any queuing system with non-zero arrival and service rate?

O W will certainly change but we are unsure of it increases or decreases.

O W will not change

O There is not enough information to answer this question.

O W will decrease.

O W will increase.

You stand in line to buy a ticket to see a movie. There are two service windows staffed with employees to complete the ticket transaction. Which type of queuing line structure do you encounter? O Multi-channel, single phase Multi-channel, multi-phase Single channel, single phase Kendall's structure Single channel, multi-phase Question 3 2 pts The arrival of airplanes at a one-runway airport follows a Poisson distribution with a mean rate of 8 planes per hour. The landing time can be modeled with an exponential distribution with a mean of 5 minutes per airplane. What is the average number of airplanes in the system? O 0.625 O2 0 2.6667 O 1.6667 O 1.6 Question 4 2 pts Queuing models use a 1/2/3 notation. The number [2] represents: the distribution of service times the average service rate the time between services the time between arrivals O the average arrival rate Question 5 2 pts A stable queuing system is one that has: an overall service rate less than the arrival rate O FIFO queue discipline an overall service rate greater than the arrival rate Poisson arrivals O exponential service times
