Проблема оценки надежности систем автоматизированного управления потенциально опасными технологическими процессами всегда является актуальной. В статье приведен пример описания процесса моделирования и расчета основных показателей функциональной надежности одной из функций АСУТП операции поддавливания в технологическом процессе формования крупногабаритных изделий из смесевого композиционного материала, проведенный по технологии автоматизированного структурно-логического моделирования с использованием программного комплекса «АРБИТР». Кратко описаны основные этапы практической реализации данного метода, такие как: декомпозиция и выделение из общей структуры АСУ функциональных подсистем; формирование на их основе схем функциональной целостности; расчет системных показателей надежности. Отмечено, что описанные в статье методы проектной оценки надежности и полученные на их основе результаты, позволяют сделать вывод о высокой эффективности применения программного комплекса «АРБИТР» при решении широкого круга задач по определению фактических значений показателей надежности и комплексной оценки безопасности автоматизированных систем управления специальными химическими производствами. The problem of assessing the reliability of automated control systems for potentially hazardous technological processes is always relevant. The article gives an example of a modeling process description and calculation of the main indicators of the functional reliability of one of the APCS functions that is pressurization in the technological process of molding large-sized products from MCM (mixed composite materials) that was carried out using the automated structural-logical modeling technology with the use of the ARBITR software package. The main stages of the practical method implementation are described briefly. They are decomposition and separation of functional subsystems from the general ACS structure; formation of functional integrity schemes on their basis; calculation of system reliability indicators. The methods of design reliability assessment that are described in the article and the results obtained on their basis are obvious to conclude about high efficiency of ARBITR software package use in solving a wide range of tasks in order to determine the actual reliability indicators and get a comprehensive safety assessment of automated control systems for special chemical industries.

The paper describes one of the approaches to solving the problem of ensuring the reliability of automated manufacturing system of hazardous chemical plants using various hazardous chemicals in the production processes. Exposure to these substances can be harmful to personnel and infrastructure. Our goal is to create an automated manufacturing system that ensures not only fault-free operation, but also the safety of automated manufacturing systems of hazardous chemical plants. Depending on the type and specifics of the hazardous production, the automated manufacturing system should have a certain integral level of safety. We have developed a method for analyzing system reliability, taking into account many reliability indicators. The proposed method, considering the target probability of failure-free operation of the entire system and the probability of failure-free operation of the hazardous module required for the desired integral level of safety, determines the target probability of failure-free operation of all the system modules. It also provides for the inclusion of not only functional modules into the system, but also modules that block failures and dangerous effects. The paper considers an example of chemical production, however, the proposed method is applicable to a wide range of technological processes of hazardous industries.
