Abstract

 
 
 
 The article presents the main propositions of logical-probabilistic method of analysis the assurance and enhancement of reliability of structurally complex systems, in which the structure of the system is described by means of mathematical logic and quantitative assessment of reliability is performed using probability theory. An example build script the dangerous condition and performed a quantitative investigation of the reliability of complex systems with interdependent basic events. The methods and models are implemented in a computer system that provides the ability to objectively assess the reliability and safety of structurally complex systems and solving problems of operational decision-making in complex emergencies.
 
 
 
Highlights
To solve successfully the task of ensuring the health and safety of people in modern conditions is possible only for a range of activities and, above all, the prevention of industrial accidents
The mathematical apparatus of logic-probabilistic method (LPM) developed on the basis of theoretical works Georg Boole, who saw a connection between logic and probability, and K.E
[1] LPM was defined as the method of calculation of reliability of structurally complex systems, in which the structure of the system is described by means of mathematical logic and quantitative assessment of reliability is performed using probability theory
