Exam 7: Service Processes

A department of 25 machines is kept running by three operators who respond to randomly occurring equipment problems. When an operator is absent, the amount of production being lost by machines waiting for service increases. The analyst can use queuing theory analysis to determine whether to pay overtime to an operator from a different shift or not.

The demand on a hospital's emergency medical services is considered a controllable arrival pattern of the calling population.

The term "queue discipline" involves the art of controlling surly and unruly customers who have become irritated by waiting.

In the service-system design matrix, a face-to-face total customization service encounter is expected to have which of the following?

Which of the following is a suggestion for managing queues presented in the textbook?

Buying a ticket for a college football game where there are multiple windows to buy the ticket at features which type of queuing system line structure?

Getting an autograph from a famous person might involve standing in which type of queuing line structure?

The service blueprint makes a distinction between:

Highest-profit customer first is a queue discipline discussed in the textbook.

In the service-system design matrix, an internet and on-site technology service encounter is expected to have which of the following?

A variable arrival rate is more common in waiting line management than a constant arrival rate.

The demand on a hospital's emergency medical services is considered an uncontrollable arrival pattern of the calling population.

A department of 25 machines is kept running by three operators who respond to randomly occurring equipment problems. An analyst wanting to know whether to add a fourth operator or downsize to two operators would be helped by using queuing theory analysis.

Customers arrive at a common queue at the coffee station with two identical coffee machines in a busy mall at the rate of 48 per hour, following Poisson distribution. Each customer mixes his or her specialty coffee taking 2 minutes on an average following an exponential process. What is the expected number of customers in the system at this coffee station?

Which following queue discipline is discussed in the textbook?

The central problem in virtually every waiting line situation is a trade-off decision balancing the costs of adding services with the costs of waiting.

The customer arrivals in a queuing system come almost exclusively from finite populations.

An infinite population in waiting line management refers to a population that is large enough in relation to the service system so that the change in population size caused by subtraction or additions to the population does not significantly affect the system probabilities.

Assuming a 24 hour operation in a warehouse, and an arrival following Poisson distribution with mean rate of 36 per day and service (unloading using a single bay) following exponential distribution with a rate of 48 trucks per day, answer the following question. What is the expected waiting time in the system (in hours) for a typical truck?

There are many applications of poka-yokes in service organizations. Which of the following is one of the three-T's used to classify poka-yokes?
