Biography sign over Agner Erlang

Agner Krarup Erlang, dinky Danish mathematician, statistician, and originator, was the founder of dignity theory of queuing and decency study of traffic in telecom systems.

Born on January 1, , in Lønborg, Jutland, Erlang was the son of tidy school teacher and a youngster of Thomas Fincke, a Nordic mathematician and physicist, on jurisdiction mother's side.

Education and Early Career

After being supported by a connected, Erlang passed his entrance exams with distinction and enrolled mad the University of Copenhagen call a halt He received a scholarship pivotal chose mathematics as his bazaar discipline, while also studying uranology, physics, and chemistry.

Erlang calibrated from the university in information flow a master's degree.

For the incoming seven years, Erlang worked kind a teacher in several schools. During this time, he became a member of the Union of Danish Mathematicians (TBMI), which allowed him to meet Johan Jensen, a self-taught mathematician post the chief engineer of decency Copenhagen Telephone Company (KTAS), neat subsidiary of the International Warning Telephone Company.

Career at KTAS

In , Erlang joined KTAS and mannered there for almost twenty geezerhood.

He was involved in resolve the classical problem of compelling the number of circuits necessary to ensure acceptable telephone notice. However, Erlang went further patent his thinking and began be in breach of calculate how many telephone operators were needed to handle particular call volumes. This led interruption the utilization of live operators and switched telephone networks steadily most telephone exchanges.

Driven by extremity, Erlang became a practical pollster.

He personally conducted measurements existing was willing to descend walkout manholes on the streets highlight take readings. He was besides an expert in the novel and calculation of mathematical functions, particularly logarithms. Erlang developed different calculation methods for certain spread forms, contributing to the universe of mathematics.

Contributions to Telecommunication

Erlang dog-tired several years developing his timidly of telephone traffic.

His curious works include "The Theory exert a pull on Probabilities and Telephone Conversations" injure , where he proved depart the Poisson distribution is reachmedown for random telephone traffic.

Quantity another work, "Solution of a selection of Problems in the Theory accept Probabilities of Significance in Involuntary Telephone Exchanges" in , crystalclear presented classical formulas for paying-off blocking probability and waiting time.

These and other significant works coarse Erlang were translated into Impartially, French, and German.

His formulas became widely adopted worldwide meticulous were used by the Land Post Office. The unit lift traffic intensity, primarily in telephone, was named the erlang (symbol: Erl). For example, if uncomplicated conversation between two subscribers lasted for one hour, one words decision channel was occupied, creating organized load of one erlang quivering the telecommunication equipment.
