Вµнные результаты показывают, что при экспоненциальном распределении потока обслуживания на первой станции характер распределения на последующей станции сохраняет входное экспоненциальное распределение, при нормальном распределение меняется. Дальнейшие исследования проведем для различного количества станций и различных связей между ними при экспоненциальном распределении входного потока и потока обслуживания.
