Erlang (unit) - Wikipedia

The erlang (symbol E ) is a dimensionless unit that is used in telephony as a measure of offered load or carried load on service-providing elements such as telephone circuits or telephone switching equipment. A single cord circuit has the capacity to be used for 60 minutes in one hour. Full utilization of that capacity, 60 minutes of traffic, constitutes 1 erlang. Carried traffic in erlangs is the average number of concurrent calls measured over a given perio… WebErlang Loss Formula The formula E (ρ, N) is called the Erlang loss formula. It represents the fraction of time that the N circuits are busy. This fraction of time is also the fraction of … WebKeywords: Partition function, loss systems, closed queueing networks, asymptotic ex- pansions. 1.

Erlang Loss Models for the Static Deployment of Ambulances

WebThe function name is an atom. Each argument is a pattern. The number of arguments N is the arity of the function. A function is uniquely defined by the module name, function name, and arity. That is, two functions with the same name and in the same module, but with different arities are two different functions. WebThis paper develops the properties of the Erlang loss function, B (N, a), used in telephone traffic engineering. The extension to a transcendental function of two complex variables is constructed, thus permitting the methods of complex analysis to be employed for the further study of its properties.
