Концептуальная модель многоэтапной комплексной оценки надежности автоматизированных систем управления предприятиями

Концептуальная модель многоэтапной комплексной оценки надежности автоматизированных систем управления предприятиями

Abstract

Статья посвящена проблеме оценки свойств надежности автоматизированных систем управления предприятием на основных этапах их жизненного цикла. Рассмотрены особенности автоматизированной системы управления предприятием, как объекта исследования, отличающие ее от других систем. Исследование свойств надежности автоматизированных систем управления предприятием наиболее эффективно может быть выполнено при использовании следующих концептуальных моделей: концептуальной модели самой автоматизированной системы управления предприятием, концептуальной схемы пользователей системы, а также концептуальной схемы различных источников отказов автоматизированной системы управления предприятием. Оценка надежности автоматизированных систем управления предприятием выполняется на основе трех показателей надежности: коэффициента функциональной готовности, назначенного ресурса, коэффициента сохранения эффективности. В статье предложена новая концептуальная модель многоэтапной комплексной оценки надежности автоматизированных систем управления предприятием.

The article concerns the problem of assessment of the reliability properties of automated enterprise management systems at main stages of its life cycle. It is considered the features of automated enterprise management system that distinguish the system from other ones. The assessment of automated enterprise management systems can be performed in the most efficient way with support of the following conceptual models: a conceptual model of automated enterprise management systems, automated enterprise management system user’s conceptual scheme, a conceptual diagram of the various sources of automated enterprise management systems’ failures. The system reliability assessment is performed on the base of three parameters of reliability such as coefficient of operational availability, assigned resource, and conservation efficiency factor. The paper presents the developed conceptual model of multi-stage integrated assessment of the reliability of automated enterprise management systems.
