Queue areas are places in which people queue (first-come, first-served) for goods or services. Such a group of people is known as a queue (British usage)...

In queueing theory, a discipline within the mathematical theory of probability, an M/M/1 queue represents the queue length in a system having a single...

mathematical queueing theory, Little's law (also result, theorem, lemma, or formula) is a theorem by John Little which states that the long-term average number L...

In queueing theory, a discipline within the mathematical theory of probability, the M/M/c queue (or Erlang–C model: 495 ) is a multi-server queueing model...

In queueing theory, a discipline within the mathematical theory of probability, an M/D/1 queue represents the queue length in a system having a single...

computer science, a double-ended queue (abbreviated to deque, /dɛk/ DEK) is an abstract data type that generalizes a queue, for which elements can be added...

Tutte–Coxeter is one of the 13 such graphs. It has crossing number 13, book thickness 3 and queue number 2. The Tutte–Coxeter graph is the bipartite Levi graph...

A bucket queue is a data structure that implements the priority queue abstract data type: it maintains a dynamic collection of elements with numerical...

where A denotes the time between arrivals to the queue, S the service time distribution and c the number of service channels open at the node. It has since...

Multi-level queueing, used at least since the late 1950s/early 1960s, is a queue with a predefined number of levels. Items get assigned to a particular...
