| Summary: | Background. Simulation modeling is a powerful tool for studying the behavior
of various systems, including the «technosphere object – human» system. One of the reasons
for the use of simulation modeling is the need to increase the level of automation of the
processing of initial data for the rapid adoption of managerial decisions. The purpose of the
study is to develop a simulation model for the interaction of elements in the «technosphere
object – human» system based on risk using the Lotka – Volterra system of differential equations
using MatLAB/Simulink. Materials and methods. The study was carried out using an
integrated ecosystem approach and methods of analysis and synthesis, grouping and generalization,
as well as mathematical and simulation modeling. Results. As a result of modeling
using the phase plane, two singular points were obtained: the «center» or «focus», the stability
of which must be further investigated by mathematical methods, and the «saddle», which
is unstable in this system. Conclusions. Proceeding from this, it should be noted that if any
state of the «technosphere object – human» system satisfies us from the point of view of the
correlation between the values of technogenic risk and the risk to human health, then in all
cases it is necessary to make efforts and spend resources to maintain it, carrying out medical
treatment. preventive, environmental and technological measures.
