Видим, что полученные данные не совсем совпадают с аналитическими расчетами. Попробуем увеличить число генераций до 50000. Тогда получаем в результате данные наиболее приближенные к аналитическим, но видим, что при увеличении числа генераций увеличивается и очередь, которую можно уменьшить увеличением μ.
