Проводится сравнение моделей между собой, а также с моделями, предполагающими полное или минимальное восстановление элемента (однородный и неоднородный пуассоновские процессы соответственно). Для оценки параметров модели используется метод максимизации функции правдоподобия. Для оценки ведущей функции потока, заданной в неявном виде, наиболее популярным методом является моделирование по методу Монте-Карло. В статье рассматривается пример применения разработанной методики для расчета характеристик надежности элементов, входящих в состав штатного оборудования энергоблоков АС.</p></abstract><trans-abstract xml:lang="en"><p>The paper describes modern techniques of parametrical estimation of the failure rate leading function and the assessed failure rate under the assumption of incomplete recovery using Kijima models. Models are compared among themselves and with the models assuming full or minimal recovery of a component (homogeneous and nonhomogeneous Poisson processes respectively). For estimating model parameters, the method of maximum likelihood function is used. For estimating the failure rate leading function given in implicit form, the most popular method of modeling is the Monte-Carlo method. The paper also offers an example of application of the developed technique for calculation of reliability characteristics of components, which are part of the regular equipment of NPP power units.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неполное восстановление</kwd><kwd>модели Кижима</kwd><kwd>ведущая функция потока</kwd><kwd>параметр потока отказов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>incomplete recovery</kwd><kwd>Kijima models</kwd><kwd>rate leading function</kwd><kwd>assessed failure rate</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">Kijima M., Sumita N.
