41
Which of the following characteristics apply to queuing system?
Discuss
Answer & Solution
Answer: Option C
Solution:
Customer population and Arrival process characteristics apply to queuing system. Queuing theory is the mathematical study of the congestion and delays of waiting in line. Queuing theory (or "queueing theory") examines every component of waiting in line to be served, including the arrival process, service process, number of servers, number of system places, and the number of customers—which might be people, data packets, cars, etc.
42
Which of the following is not a key operating characteristics apply to queuing system?
Discuss
Answer & Solution
Answer: Option D
Solution:
In designing a good queuing system, it is necessary to have good information about the model. The characteristics listed below would provide sufficient information.
1. The arrival pattern.
2. The service mechanism.
3. The queue discipline.
4. The number of customers allowed in the system.
5. The number of service channels.
43
Priority queue discipline may be classified as.
Discuss
Answer & Solution
Answer: Option C
Solution:
Priority queue discipline may be classified as Pre-emptive or non-pre-emptive. For priority queues, one must distinguish pre-emptive service from non-pre-emptive service. A service discipline is said to be non-pre-emptive if, once the service to a customer is started, it is not disrupted until the whole service requirement is completed.
44
The calling population is assumed to be infinite when.
Discuss
Answer & Solution
Answer: Option A
Solution:
The calling population is assumed to be infinite when arrivals are independent of each other. The population of potential customers is refered to as the calling population. The calling population can be finite or infinite. In the systems with large population, we usually assume the population is infinite.
45
Which of the cost estimates & performance measures are not used for economic analysis of a queuing system?
Discuss
Answer & Solution
Answer: Option D
Solution:
Average waiting time of customers in the system of the cost estimates & performance measures are not used for economic analysis of a queuing system. Queuing theory (or "queueing theory") examines every component of waiting in line to be served, including the arrival process, service process, number of servers, number of system places, and the number of customers—which might be people, data packets, cars, etc.
46
A calling population is considered to be infinite when.
Discuss
Answer & Solution
Answer: Option B
Solution:
A calling population is considered to be infinite when Arrivals are independent of each other. If new customer's arrival is independent of the number of customers already in the system, the calling population is called unlimited or infinite.
47
The cost of providing service in a queuing system decreases with.
Discuss
Answer & Solution
Answer: Option D
Solution:
In designing queueing systems we need to aim for a balance between service to customers (short queues implying many servers) and economic considerations (not too many servers).
48
Service mechanism in a queuing system is characterized by.
Discuss
Answer & Solution
Answer: Option A
Solution:
Service mechanism in a queuing system is characterized by Server’s behavior. Queuing theory is the mathematical study of the delays of waiting in line, covering all aspects, from arrival time to the number of servers.
49
Probabilities of occurrence of any state are.
Discuss
Answer & Solution
Answer: Option D
Solution:
Probabilities of occurrence of any state are Collectively exhaustive, Mutually exclusive and Representing one of the finite numbers of states of nature in the system.
50
In a matrix of transition probability, the probability values should add up to one in each.
Discuss
Answer & Solution
Answer: Option A
Solution:
In a matrix of transition probability, the probability values should add up to one in each row.
