Which of the following are the three major components of a queuing system?

The source population, how the customer exits the system, and the servicing system

Assume the service rate for a queue in a truck-loading operation is 2 trucks per hour. Using the infinite queuing notion for the models presented in the textbook, which of the following is the average service time?

0.5 hour

Name two things that are not a suggestion for managing queues presented in the textbook?

Determine an acceptable waiting time for your customers. periodically close the service channel to temporarily disperse the line.

Buying food at a large food store with multiple checkout counters features which type of queuing system line structure?

Multichannel, single phase

Standing in line to buy a ticket for a movie where there are multiple windows at which to buy tickets is which type of queuing system line structure?

Multichannel, single phase

A company is concerned about the number of customers who have to wait for service in its customer service department. Assume the rate at which customers are serviced is 12 per hour. Using the infinite queuing notion for the models presented in the textbook, which of the following is the mean time between arrivals?

None of these

In modeling a simulation, random numbers from 00 to 99 are assigned with the intervals determined from frequency distributions for each behavior occurrence. Assume there are two behaviors, X and Y, out of 50 tallies. On behavior X you record 20 tallies, and on behavior Y you record 30 tallies. Which of the following is a correct random-number interval for behavior X?

00 to 39

In modeling a simulation, random numbers from 00 to 99 are assigned with the intervals determined from frequency distributions for each behavior occurrence. Assume there are two behaviors, A and B, out of 100 tallies. On behavior A you record 45 tallies, and on behavior B you record 55 tallies. Which of the following is a correct random-number interval for behavior A?

00 to 44

A small vendor has either a good day of sales with an average of $1,000 or a bad day with an average of only $500 for the day. To simulate these outcomes, random numbers from 00 to 99 should be assigned with the intervals determined from the frequency distribution. If, during the last 100 days, the vendor had 27 good days and 73 bad days, which of the following is a correct random-number interval for a bad day?

27 to 99
