On the automated survivability evaluation technology and safety for russian navy ships
The article was published in issue no. № 2, 2014 [ pp. 131-135 ]Abstract: Many military shipbuilding specialists connect the numerous accidents and disasters which occurred on ships after the World War II with their insufficient survivability. The paper states that the ship safety is the main feature which can withstand accidents and probable damage in the peacetime during the ship service process under routine con ditions. The au-thors analyse the “safety” term, used in the Russian Navy. They also propose an approach to develop an automated assess-ment technology for this term. This method is based on a minimum level criterion of ship operation. The article describes and proves events which should be excluded to ensure such level of the ship functioning. The ship safety criteria definition is based on its functional efficiency of preventing these events by means (systems) of the ship. Definitions and basic parities to describe their parameters calculation are given. It is offered to enter two management levels of the ship and its means (sys-tems) at struggle for safety: low at manual and high at remote control by means (systems) of the ship. The re is an example of possible division of the ship on emergency regions . Their equipment and mechanisms fall within the scope of adverse factors of various accidents. Safety estimations formalization is based on allocation of the functional -independent operations which are carried out by significant elements of the ship means (systems) on maintenance a minimal necessary level of its functio n-ing. It also is based on construction of functional -topological circuits of elements and structural -logic circuits of these opera-tions performance conditions as direct graph. Quantitative values of functional-independent operations performance parame-ters are calculated according to corresponding circuits to logic expressions.

Аннотация:Многочисленные аварии и катастрофы на кораблях в послевоенный период многие специалисты в области военного кораблестроения связывают с их недостаточной живучестью. Авторы статьи утверждают, что в мирное время при эксплуатации корабля в повседневных условиях основным его свойством, противостоящим авариям и возможному ущербу от них, является безопасность. Приводится анализ существующего в ВМФ термина «безопасность» и предлагается подход к разработке технологии его автоматизированной оценки, в основу которого положен критерий минимально необходимого уровня функционирования корабля. Перечислены и обоснованы события, которые должны быть исключены для обеспечения такого уровня функционирования корабля. Полнота выполнения техническими средствами (системами) корабля задач по предотвращению этих событий положена в основу определения критериев его безопасности. Даются определения и основные соотношения для вычисления характеризующих их показателей. Предложено ввести два уровня управления кораблем и его техническими средствами (системами) при борьбе за безопасность: низкий при ручном и высокий при дистанционном управлении техническими средствами (системами) корабля. Приведен пример возможного деления надводного корабля на аварийные участки, оборудование и механизмы которых попадают под действие поражающих факторов различных аварий. Формализация оценок безопасности базируется на выделении функционально самостоятельных операций, выполняемых значимыми элементами технических средств (систем) корабля по обеспечению минимально необходимого уровня его функционирования, и на построении функционально-топологических схем элементов и структурно-логических схем условий выполнения этих операций в виде ориентированного графа. Количественные значения показателей выполнения функционально самостоятельных операций вычисляются по соответствующим схемам логическим выражениям. Рассмотрен порядок определения оценки безопасности проектируемых кораблей по введенным критериям и показателям и выработки рекомендаций для повышения их безопасности. В заключительной части статьи дается ряд предложений по повышению безопасности кораблей ВМФ.

Many military shipbuilding specialists connect the numerous accidents and disasters which occurred on ships
after the World War II with their insufficient survivability. The paper states that the ship safety is the main feature which can
withstand accidents and probable damage in the peacetime during the ship service process under routine con ditions. The au-thors analyse the “safety” term, used in the Russian Navy. They also propose an approach to develop an automated assess-ment technology for this term. This method is based on a minimum level criterion of ship operation. The article describes and
proves events which should be excluded to ensure such level of the ship functioning. The ship safety criteria definition is
based on its functional efficiency of preventing these events by means (systems) of the ship. Definitions and basic parities to
describe their parameters calculation are given. It is offered to enter two management levels of the ship and its means (sys-tems) at struggle for safety: low at manual and high at remote control by means (systems) of the ship. The re is an example of
possible division of the ship on emergency regions . Their equipment and mechanisms fall within the scope of adverse factors
of various accidents. Safety estimations formalization is based on allocation of the functional -independent operations which
are carried out by significant elements of the ship means (systems) on maintenance a minimal necessary level of its functio n-ing. It also is based on construction of functional -topological circuits of elements and structural -logic circuits of these opera-tions performance conditions as direct graph. Quantitative values of functional-independent operations performance parame-ters are calculated according to corresponding circuits to logic expressions.
