Abstract:
Organizational and methodological problems of providing reliability for automation means complexes of secured automated information systems based on analysis, generalization, and evaluation of experience of supervisions on their operations are considered. The article shows some factors which determine lead-up and operational time of maintenance and repairs concerning electronic components. The suggestions regarding the structure of the spare parts list and the components quantity and their utilizations during repair work organization as like as four-level hierarchical structure are justified by the authors. Calculations of stock necessity of spare parts at the object are presented. Finally, there is an example of real calculations regarding quantity of necessary spare parts stock to achieve conditions of reliability.
Keywords:Secured Automated Information System; reliability; hardware failures; hierarchical principles; spare parts list; system recovery; sufficiency of spare parts parameter.
