  2. Queue (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Queue_(abstract_data_type)

    In a FIFO data structure, the first element added to the queue will be the first one to be removed. This is equivalent to the requirement that once a new element is added, all elements that were added before have to be removed before the new element can be removed. A queue is an example of a linear data structure, or more abstractly a ...

  3. Bucket queue - Wikipedia

    en.wikipedia.org/wiki/Bucket_queue

    A bucket queue has the form of an array of buckets: an array data structure, indexed by the priorities, whose cells contain collections of items with the same priority as each other. With this data structure, insertion of elements and changes of their priority take constant time. Searching for and removing the minimum-priority element takes ...

  4. Queueing theory - Wikipedia

    en.wikipedia.org/wiki/Queueing_theory

    Queue networks are systems in which multiple queues are connected by customer routing. When a customer is serviced at one node, it can join another node and queue for service, or leave the network. When a customer is serviced at one node, it can join another node and queue for service, or leave the network.

  5. FIFO (computing and electronics) - Wikipedia

    en.wikipedia.org/wiki/FIFO_(computing_and...

    Representation of a FIFO queue. In computing and in systems theory, first in, first out (the first in is the first out), acronymized as FIFO, is a method for organizing the manipulation of a data structure (often, specifically a data buffer) where the oldest (first) entry, or "head" of the queue, is processed first.

    Examples M: Markovian or memoryless [6] Exponential service time. M/M/1 queue: M Y: bulk Markov: Exponential service time with a random variable Y for the size of the batch of entities serviced at one time. M X /M Y /1 queue: D: Degenerate distribution: A deterministic or fixed service time. M/D/1 queue: E k: Erlang distribution

  8. Mean value analysis - Wikipedia

    en.wikipedia.org/wiki/Mean_value_analysis

    Now write L i (n) for the mean number of customers at queue i when there is a total of n customers in the system (this includes the job currently being served at queue i) and W j (n) for the mean time spent by a customer in queue i when there is a total of n customers in the system. Denote the throughput of a system with m customers by λ m.

  9. M/M/∞ queue - Wikipedia

    en.wikipedia.org/wiki/M/M/%E2%88%9E_queue

    An M/M/∞ queue is a stochastic process whose state space is the set {0,1,2,3,...} where the value corresponds to the number of customers currently being served. Since, the number of servers in parallel is infinite, there is no queue and the number of customers in the systems coincides with the number of customers being served at any moment.
