单词 queuing theory
释义
queuing theory

Mathematics
  • A study of the processes relating to customer wait and service time patterns where there is a random element involved in one or other or in most cases both parts. In various contexts, the probability model for each part can be quite different, and the randomness of each stage makes analysis appropriate for simulations where the behaviour of the queue can be observed repeatedly for a variety of parameter values in order to investigate the effect of a variety of management strategies.


Computer
  • The study of systems in which customers, arriving at random and requiring varying periods of service, may have to wait in order to be served. From the number of service points and the probability distributions of arrival times and service times, the distribution of the length of queue and the waiting time before service may be predicted.

    Queuing theory has important applications in any system liable to congestion, where the costs of improved service may be balanced against the costs of congestion.
