Получена нечеткая оценка для средней прибыли от эксплуатации комплекса в единицу времени. Приведен пример численного вычисления исследуемого показателя эффективности с нечеткими параметрами.</p></abstract><trans-abstract xml:lang="en"><p>The present work offers the method of estimation of economic efficiency indicators of the automated technological facility “protection object – safety system” with recoverable elements considering the uncertainty of a model’s parameters. The fuzzy estimation for the average profit of facility operation per time unit is obtained. The example of numerical evaluation of the examined indicator of efficiency with fuzzy parameters is given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глубина восстановления</kwd><kwd>интенсивность отказов</kwd><kwd>ремонт</kwd><kwd>замена</kwd><kwd>периодичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reliability</kwd><kwd>profit</kwd><kwd>efficiency</kwd><kwd>safety system</kwd><kwd>stochastic variables</kwd><kwd>a mean lifetime</kwd><kwd>casual process</kwd><kwd>mathematical time expectations</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">Перегуда А.И., Тимашов Д.А.
