We have used the neutrosophic statistical interval method introduced by F. Smarandache to describe the parameters of the Erlang service queueing model and to find the neutrosophic performance measures. 2020 106 112 467 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.060202 https://www.americaspg.com/journal/21/article/467 https://www.americaspg.com/storage/1305.pdf
