Wgner friends nicknamed him “The Private Person”. He died some days later on Sunday, 3rd February Skip to main content. His work on probability theory led him to join the Mathematical Association, where he met Johan Jensen, chief engineer at the Copenhagen Telephone Company.

Without this knowledge it would be a challenge to say the least for designers to establish the necessary trunk group sizes for their networks to kdarup efficient and scalable. Erlang died in in Copenhagen.

Nyt Tidsskrift for Matematik. This interest is described in: Please help to improve this article by introducing more precise citations. Jensen persuaded Erlang to join the telephone company and find a solution to the problem of waiting times for telephone calls.

A comprehensive survey of his works is given in “The life and works of A. His studies at Copenhagen were in mathematics and natural science. He published his first paper on these problems The theory of probability and telephone conversations in The foundation of any good call center outsourcer is a proper understanding of Erlang and thus queueing theory.

He won a scholarship to the University of Copenhagen and completed his studies there in as an MA with mathematics as the main subject and astronomy, physics and chemistry as secondary subjects. His major was mathematics but he chose physics, astronomy, and chemistry as minor studies.

For a call center looking to maximize agent utilization, these concepts resonate strongly with FCR. Erlang at once started to work on applying the theory of probabilities to problems of telephone traffic and in published his agmer work on it “The Theory of Probabilities and Telephone Conversations” [1] proving that telephone calls distributed at random follow Poisson’s law of distribution.

In Erlang joined the Copenhagen Telephone Company and began applying probability to various problems arising in the context of telephone calls.

Agner returned home where he remained for two years, teaching at his father’s school for two years and continuing with his studies. He was also an expert in the history and calculation of the numerical tables of mathematical functions, particularly logarithms. For example, if a team of agents handled 50 calls in one hour, and each call had an drlang call length of 10 minutes, then the number of Erlangs this represents could be worked out as follows: Even though his natural inclination was toward scientific research, he proved to have excellent teaching qualities.


Erlang devoted all his time and energy to his work and studies.

Change settings No, thanks. Out of necessity, Erlang was a hands-on researcher.

Understanding Erlang and Queuing Theory

He devised new calculation methods for certain forms of tables. Further publications followed, the most important work was published in “Solution of some Problems in the Theory of Probabilities of Significance in Automatic Telephone Exchanges” erlangg. He attended the mathematics lectures of Zeuthen and Juel and these gave him an interest in geometrical problems which were to remain with him all his life.

Can you beat our games? He maintained his interest in mathematics, and received an award for a paper that he submitted to the University of Copenhagen.
