Применение показателя структурной отказоустойчивости при поддержке принятия решений на этапе проектирования

Abstract

Рассматриваются вопросы, связанные с разработкой и применением для расчета показателей надежности ускоренных методов моделирования. Предложено для оценки структурной отказоустойчивости сложных систем, структурная модель которых может быть сведена к нейроподобной, использовать информационную структурную статистическую модель. На примере очистительных сооружений показана возможность сравнивать выбранные конструкции по полученным значениям показателя структурной отказоустойчивости.This article discusses issues related to the development and application for the calculation of reliability indices of structural information of the statistical model. In determining the parameters of reliability specialist must have the necessary statistical data. It establishes the necessary data on the results of the experiments of the reference guide their own experiences, and the final result of the quantified characteristics will depend on his or her qualifications and correctness of the methods and models. To ensure reliable operation of the decision of problems of a technical object at all stages of its life cycle urgent task is the use of a single information approach satisfies the requirements of CALS-technologies, the use and application of appropriate mathematical apparatus and software, can significantly reduce the time spent on the design and maintenance of the product. The paper presents an information-structural statistical model for estimating the probability of failure-free operation of a complex system. The result of this model is to obtain the values of the index of structural fault tolerance. As a result, when considering possible options for the structure of the proposed facility, this approach allows them to compare the largest index. On the example of treatment facilities the possibility to compare the selected design on the obtained values of the index of structural fault tolerance.
