Cognitive-impulse model for assessing complex technical systems survivability

Abstract

The article proposes to assess the system components failure risk during diagnostics based on the research methods analysis results and complex technical systems models, in order to ensure their survivability. The authors developed a method for assessing the survivability of systems based on cognitive- impulse modeling and interaction with a complex technical system, as with a digraph subjected to the impulse action of simulation modeling impulses. The created cognitive-impulse model allows us to evaluate the survivability, the degree of structural and functional damage to the complex technical system components and intercomponent connections. The developed cognitive-impulse model of survivability assessment has flexibility - the ability to use the method at any level of subsystem components failure risk assessment with their various configurations; adaptability - the ability to adapt to changes in the configuration of complex technical systems subsystems. The developed software allows to obtain both numerical and graphical results of various classes technical systems cognitive-impulse models studies and complexity. The developed cognitive- impulse model effects over a complex technical system makes it possible to establish emergency and pre-emergency conditions for its subsystems.
