The main defects of railway structures are identified, the damage of defects is characterized by the degree of influence based on the quality indicators of building structures, a mathematical model for assessing risk and damage is created, expert surveys are conducted on the nature of the conditions for the probability of defects and bringing them to damage, an algorithm for implementing the results on the construction site is presented.
Keywords: risk assessment, probability conditions, concrete works, risk-oriented approach, risk identification
The authors implemented methodological apparatus homeostatics used to determine the effect of the internal contradictions of the processes of functioning and development of socio-economic systems and management to the survival of the system and its transition to a new stable state.
Keywords: structural and functional stability of the transport and logistics cluster, the cybernetic approach Homeostatics
Using the expression for the dynamic model calculations were performed, identified analytical and graphical relationship between resistance, systemic and the number of enterprises - participants cluster associations to characterize the sustainability of transport and logistics cluster to fluctuations in external traffic
