    Assessment and forecast for the creation of photochemical smog over transport overpasses in Kyiv
    (ІТГІП, 2018) Sipakov, Rostislav; Trofimovich, Volodimir; Voloshkina, Olena; Bereznitska, Julia
    This article deals with the analysis of existing models of smog situation formation over automobile overpasses and in places of substantial congestion of transport in large cities, for example, in Kyiv. A mathematical model consisting of two blocks – dynamic and kinetic, which allows determining the formation of the thermal dome of pollution and the concentration of hydrocarbon emissions in the air, depending on the number of working engines, is proposed. The kinetic block of the model allows determining the level of formaldehyde, as an indicator of the appearance of photochemical smog in conditions of atmospheric constancy. The concentration of emissions from motor vehicles in the air is calculated over the main transport overpasses of the city of Kyiv at their full load (peak hours).

    Research of the use of «ecological niche» model for definition of production risk indicators
    (ІТГІП, 2018) Gunchenko, Oksana; Voloshkina, Olena
    The issues of improving the methodology for determining the risk of labor activity using the model of «ecological niche» are considered in the presence of a number of harmful and dangerous factors for human beings in the production environment. The possibility of using an ecological niche for mathematical modeling and industrial risk indicators has been established, but it has been proved that it is necessary to consider that the response to one factor may depend on the influence of another of the existing harmful and dangerous production factors. This approach allows us to develop a multi-criteria mathematical model for determining the production risk, but it is necessary to take into account the changes in the parameters of the MHF, which complicates the problem, since the effects of the exceedances in the same percent are different for all harmful and dangerous production factors.
