Erlang (Agner Krarup Erlang)

Agner Krarup Erlang was a Danish mathematician and engineer who developed models to analyze telephone traffic and network capacity. His work introduced the concept of how many calls or data connections a system can handle simultaneously, using statistical methods. Erlang formulas help determine the optimal number of lines or resources needed to ensure efficient service without congestion or wasted capacity. His contributions are fundamental in telecommunications for designing reliable, efficient networks that balance capacity with demand, ensuring users experience minimal delays or dropped connections.
