Эта задача является актуальной при реконструкции объектов культурного наследия, имеющих поврежденные несущие конструкции из дерева. В качестве протезов применены рамные стержневые системы, для которых рациональные решения находятся на дискретных множествах варьируемых параметров с использованием микрогенетического алгоритма. В отличие от классической схемы эволюционного моделирования вводится только оператор адаптивной многоточечной мутации. Целевая функция формируется с возможностью учета приоритетов осуществления как единовременных затрат на устройство протезирования, так и затрат на эксплуатацию в течение расчетного периода. Приведен пример проектирования протезирования балки, где с помощью восстановительного опорного и превентивно устанавливаемого пролетного протезов обеспечивается требуемая прочность и жесткость конструкции.</p></abstract><trans-abstract xml:lang="en"><p>The technique of optimal design of the recovery systems for the bearing capacity of timber beams using prosthetics with steel spatial systems is considered. This task is relevant for the reconstruction of cultural heritage sites that have damaged structural structures made of wood. Rational solutions are discrete sets of variable parameters using a micro genetic algorithm that uses, unlike the classical scheme of evolutionary modeling, only the operator of an adaptive multi-point mutation. The objective function is formed with the possibility of taking into account the priorities for the implementation of both the one-off costs for the device of prosthetics and the costs of operation during the exploitation period. An example of beam prosthesis is given where the required strength and rigidity of the structure is provided with the help of a restorative supporting and preventively installed span prosthesis. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>эволюционное моделирование</kwd><kwd>микрогенетический алгоритм</kwd><kwd>протезирование деревянных конструкций</kwd><kwd>восстановление несущей способности</kwd><kwd>адаптивная мутация</kwd><kwd>оптимизация</kwd><kwd>прочность</kwd><kwd>жесткость</kwd><kwd>объекты культурного наследия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>evolutionary modeling</kwd><kwd>micro genetic algorithm</kwd><kwd>recover of timber structures</kwd><kwd>bearing capacity</kwd><kwd>adaptive mutation</kwd><kwd>optimization</kwd><kwd>strength</kwd><kwd>rigidity</kwd><kwd>objects of cultural heritage</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">Колчунов В.И., Пятикрестовский К.П.
