Исследовано влияние ремонтопригодности на надежность технической системы. Невысокая ремонтопригодность является одной из причин того, что поступающие в подразделения и участки машины требуют частых остановок для замены недолговечных элементов, регулировки и устранения отказов. Разработана методика управления надежностью технических систем путем улучшения ее ремонтопригодности. Проанализированы существующие методы оценки ремонтопригодости систем и предложена усовершенствованная методика управления надежностью технических систем путем улучшения ее ремонтопригодности, используя теорию графа. Получен и введен показатель ε, названный фактором совершенства.В процессе использования технической системы потребитель несет большие убытки из-за отказов. Это прежде всего прямые затраты на устранение самого отказа и убытки от простоя отказавшей техники. Надежность системы в общем случае определяется долговечностью, безотказностью, ремонтопригодностью и сохранностью.Нередко для замены быстро изнашивающегся элемента необходимо почти полностью разбирать систему, нарушая взаимосвязи узлов и деталей. Следовательно, серьезные конструктивные недостатки техники вызывают большие затраты рабочего времени и материальных ресурсов при их использовании потребителями.В предлагаемой методике учитывается технологическая последовательность разборочных работ при капитальном ремонте, использование утвержденных технических норм времени на разборно-сборочные работы.Результаты ранних исследований авторов показывают, что технологический процесс разборки систем при разборке на элементы заключает в себе 7 уровней доступности, а двигателя на детали – 4. На показатели ремонтопригодности существенное влияние оказывает уровень доступности элементов системы. На основании этого далее предлагается взаимоувязать показатель надежности элементов системы с уровнем их доступности.</p></abstract><trans-abstract xml:lang="en"><p>Identified and analyzed factors, along with maintainability, determining the reliability of the technical system. The influence of maintainability on the reliability of a technical system is investigated. Low maintainability is one of the reasons that entering the units and sections of the machine require frequent stops to replace short-lived elements, adjust and eliminate failures. A technique for managing the reliability of technical systems by improving its maintainability has been developed. The existing methods for evaluating the maintainability of systems are analyzed and an improved technique for managing the reliability of technical systems by improving its maintainability using the graph theory is proposed. The indicator ε, called the perfection factor, is obtained and introduced.In the process of using the technical system, the consumer suffers large losses due to failures. This is primarily the direct costs of eliminating the failure itself and losses from the downtime of the failed equipment. The reliability of the system in the general case is determined by the durability, reliability, maintainability and safety.Often, to replace a wearing element, it is necessary to almost completely disassemble the system, disrupting the relationships of components and parts. Consequently, serious design flaws in technology cause a large expenditure of working time and material resources when used by consumers. The proposed methodology takes into account the technological sequence of dismantling work during overhaul, the use of approved technical standards for time for dismantling and assembling.The results of early research by the authors show that the technological process of disassembling systems when disassembling into elements comprises 7 levels of accessibility, and the engine for parts - 4. The level of accessibility of system elements has a significant impact on maintainability indicators. Based on this, it is further proposed to interlink the reliability indicator of system elements with the level of their availability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ремонтопригодность</kwd><kwd>теория надежности</kwd><kwd>теория графов</kwd><kwd>фактор совершенства</kwd><kwd>показатели ремонтопригодности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>maintainability</kwd><kwd>reliability theory</kwd><kwd>graph theory</kwd><kwd>perfection factor</kwd><kwd>maintainability indicators</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">Wu-Lin Chen.
