Exam 21: The Modi and Vam Methods of Solving Transportation Problems

A university has several technicians in the repair station to care for the computers in the student labs. This system is most likely

A waiting line meeting the M/M/1 assumptions has an arrival rate of 10 per hour and a service rate of 12 per hour. What is the average time a unit spends in the system and the average time a unit spends waiting?

The source population is considered to be either __________ in its size.

In a repetitive focus factory, the number of channels available for the processing of a certain part would likely refer to

Provide an example of a limited or finite population for a queue.

A waiting line meeting the M/M/1 assumptions has an arrival rate of 10 per hour and a service rate of 12 per hour. What is the probability that the waiting line is empty?

Which one of the following is not a characteristic of a Model C or M/D/1 system?

In the analysis of queuing models, the Poisson distribution often describes arrival rates and service times are often described by the negative exponential distribution.

A queuing model which follows the M/M/1 assumptions has λ = 3 and μ = 2. The average number in the system is

What does it mean to have a patient customer in a waiting line?

A finite population waiting line model with a single server has an average service time T of 50 minutes and an average time between service requirements U of 350 minutes. Calculate the service factor X. If the population consists of 5 elements, what are the average number waiting, the average number being serviced, and the average number running? Refer to Table D.8.

A concert hall, employing both ticket takers and ushers to seat patrons, behaves typically as a

A waiting line meeting the M/M/1 assumptions has an arrival rate of 4 per hour and a service rate of 12 per hour. What is the average time a unit spends in the system and the average time a unit spends waiting?

What is the waiting-line problem? Why is it important to operations?

The common measures of a queuing system's performance include

Why does it matter whether a population of arrivals is limited or unlimited? Compose your answer in a well-organized, convincing paragraph.

Most banks have changed from having a line in front of each teller to a system where one line feeds all tellers. Which system is better? Why?

In queuing problems, arrival rates are generally described by the normal probability distribution.

The greater the margin by which the arrival rate exceeds the service rate, the better the performance of the waiting line.

A university has only one technician in the repair station to care for the computers in the student labs. This system is most likely
