Предлагается использовать редукцию рёбер и упорядочивать рёбра при расчёте надёжности известным методом ветвления. Данные приёмы существенно сокращают время расчёта надёжности сети с ограничением на диаметр, что подтверждается приведёнными результатами численных экспериментов.</p></abstract><trans-abstract xml:lang="en"><p>Calculating diameter constraint network reliability is NP-hard problem. The methods for edge reduction and special ordering of edges while calculating the reliability index by the well-known factoring method are proposed. Experiments show a considerable speeding up of diameter constraint network reliability computations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>надёжность сети</kwd><kwd>случайный граф</kwd><kwd>диаметр сети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>network reliaЬility</kwd><kwd>random graph</kwd><kwd>diameter constraint</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Colbourn Ch.
