Agner Krarup Erlang

Agner Krarup Erlang was a Danish engineer and mathematician known for developing models to analyze telephone traffic and call patterns. His work helped determine the necessary number of phone lines and capacity to handle varying call volumes efficiently, ensuring quality service without excessive costs. Erlang’s formulas are still used today in telecommunications to predict traffic load, optimize infrastructure, and improve network reliability. His contributions provided a scientific basis for managing communication systems as they grew in complexity, influencing modern network planning and capacity management principles.
