Choose difficulty:

Beginner

Intermediate

Advanced

What is the main goal of using queuing models like M/M/1/N?

a: To minimize the average waiting time of customers Explanation

Explanation

b: To maximize the number of customers in the system Explanation

Explanation

c: To reduce the utilization factor of the service provider Explanation

Explanation

d: To increase the variability of the service time distribution Explanation

Explanation

What happens if the arrival rate exceeds the service rate in an M/M/1/N queuing system?

a: The waiting time increases indefinitely Explanation

Explanation

b: The system becomes unstable and breaks down Explanation

Explanation

c: The utilization factor decreases Explanation

Explanation

d: The queue capacity is exceeded and customers are turned away Explanation

Explanation

What is the utilization factor in an M/M/1/N queuing model?

a: The ratio of the arrival rate to the service rate Explanation

Explanation

b: The ratio of the service rate to the arrival rate Explanation

Explanation

c: The ratio of the arrival rate to the product of the service rate and the maximum number of customers Explanation

Explanation

d: The ratio of the service rate to the product of the arrival rate and the maximum number of customers Explanation

Explanation

What is the difference between an M/M/1 queuing system and an M/M/1/N queuing system?

a: M/M/1/N has a finite queue capacity, while M/M/1 does not have a queue capacity Explanation

Explanation

b: M/M/1 has a finite queue capacity, while M/M/1/N does not have a queue capacity Explanation

Explanation

c: M/M/1 has multiple servers, while M/M/1/N has a single server Explanation

Explanation

d: M/M/1/N has multiple servers, while M/M/1 has a single server Explanation
