A. K. Erlang

A. K. Erlang was a Danish mathematician and engineer who developed methods to analyze telephone traffic and capacity. His work helps determine how many telephone lines are needed to handle a specific volume of calls without excessive wait times or wasted lines. Essentially, Erlang’s formulas model call patterns, call durations, and network usage, helping service providers efficiently plan and manage communication systems. His contributions are fundamental in telecommunications, ensuring reliable service while optimizing infrastructure costs.
