The probabilistic analysis of the remote monitoring systems of critical infrastructure safety

Zhulina S., Kuznetsova T., Kostogryzov A., Kurpatov O., Nistratov A., Nistratov G.

183--188

The approach for probabilistic analysis of the remote monitoring systems (RMS) of critical infrastructure safety (CIS) is proposed. It allows to estimate the reliability and timeliness of information producing, the completeness, validity and confidentiality of the RMS information. In application to composed and integrated CIS with RMS and without RMS the earlier models, developed by authors, are used. The methods for evaluating influence of RMS quality on risk to lose CIS integrity are developed. Some effects of RMS applications in Russia are demonstrated.

The approach for analytical modelling operation processes of composed and integrated information systems is proposed. It allows to estimate the reliability and timeliness of information producing, the completeness, validity and confidentiality of the used information from users’ point of view. In application to composed and integrated systems the existing models are developed by introducing the space of elementary events for operation processes from system engineering point of view. It is intended for systems analysts for any IS. Some effects are demonstrated by examples.

Applicable technologies to forecast, analyze and optimize reliability and risks for complex systems

Kostogryzov A., Nistratov G., Nistratov A.

Journal of Polish Safety and Reliability Association

2012

Vol. 3, No. 1

1--14

The paper is concerned with the application of the original mathematical models and supporting them software technologies to forecast, analyze and optimize reliability and risks for complex systems (system is defined as a combination of interacting elements organized to achieve one or more stated purposes). Functionality and usability to analyze information system processes and standard processes in system life cycle are presented. Rational use of the proposed results allows to go «from a pragmatical filtration of information to generation of the proved ideas and effective decisions». Effects are demonstrated by examples.
