Нечітке моделювання поведінки елементів хімічного обладнання

Abstract

This work is devoted to the creation of new models of metallic constructions behavior with changing geometric characteristics as a result of corrosion and effective digital algorithms of their computer implementation with fuzzy information about environmental parameters.Fuzzy information is formalized using the theory of fuzzy sets. A new mathematical task statement of durability prediction of corroding constructions with fuzzy parameters of aggressive environment are formulated. Rate of corrosion is considered as interval value given by linguistic variable value. Linguistic variable degree of "aggressiveness of the environment" is considered. Aggressive environment parameter is presented as expansions in α-level sets.The result of the solution of the prediction of durability will be a tuple of values of durability of construction. It is converted to a clear number by the known methods of the theory of fuzzy sets

В работе рассмотрена математическая модель коррозионного износа элементов химического оборудования при нечёткой информации о параметрах агрессивной среды. Скорость коррозии рассматривается как интервальная величина, заданная значением лингвистической переменной. Используя прямые экспертные оценки, предлагается рассматривать её как нечёткое число с заданной функцией принадлежности, которое представляется в виде разложения по α-уровневым множествам

В роботі розглянуто математичну модель корозійного зносу елементів хімічного обладнання при нечіткій інформації про параметри агресивного середовища. Швидкість корозії розглядається як інтервальна величина, що задана значенням лінгвістичної змінної. Використовуючи прямі експертні оцінки, пропонується розглядати її як нечітке число с заданою функцією належності, яке представлене у вигляді розкладання по α-рівневим множинам
