Why, Where and When to Queue, A Comparative Study
Journal Title: International Journal of Scientific Research and Reviews - Year 2013, Vol 2, Issue 3
Abstract
In everyday life, we observe that, the numbers of people arrive at a cinema-ticket-window. If the people arrive ‘frequently’, they will have to wait for getting their tickets. Under such circumstances, the only alternative is to form a ‘queue’, called the ‘waiting- line’. Thus we see that queues or waiting-lines are very common in modern civilized life as at bus-stops, doctors’ clinics, bank-counters, traffic-lights, reservation-office, counters of super-market etc. In festive season we can see a queue at temples also. But for queuing theory purpose it may be remembered that the queue need not be a physical line, it may be a dispersed list of persons e.g. waiting list for a berth on a train. Queues are found in workshops also, where the machines wait to be repaired, in factories where manufactured goods wait to supply, store-rooms where articles wait to be used, incoming-calls wait to mature in telephone-exchange, ships wait to be unloaded, aeroplanes wait to take-off, vehicles waiting to proceed and so on. Such lists are as real as physical queues. In computer science a sequence of stored data or programs a waiting processing are the examples of queue. Computer programs often work with queues as a way to order tasks. For example, when the CPU finishes one computation, it will process the next one in the queue. A printer queue is a list of documents that are waiting to be printed. When we decide to print a document, it is sent to the printer queue, if there are no jobs currently in the queue, the document will be printed immediately. However, if there are jobs already in the queue, the new document will be added to the list and printed when the other have finished. Most printers today come with software that allows us to manually sort, cancel and add jobs to the printer queue.
