SIMULATION MODELING OF THE INTERACTION OF A HUMAN AND AN OBJECT OF TECHNOGENICS ON THE BASIS OF RISK

Abstract

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.
