In the analysis of the project documentation of a two-storeyed sports complex it was established that despite compliance of the project to all standards in the fire safety field, under certain conditions there is a danger of a delay of full people evacuation from the gym room in case of fire that can entail people’s death. For the purpose of ensuring fire safety several versions of space-planning decisions were considered. The scientific literature analysis showed efficiency of game theory use in the field of fire safety, however in the field of fire safety in construction it was not applied yet. Game theory Application (games with the nature in the conditions of uncertainty) for the revealed problem solution was proved. Three possible scenarios of emergence and development of the fire and four alternative space-planning decisions were considered. For all development scenarios of the fire time of critical values achievement of dangerous fire factors was defined. All necessary evacuation schemes are made and calculations are executed. On the calculated parameters basis the payoff matrix was constructed. An optimal variant of space-planning decisions was chosen. Research results showed expediency and efficiency of game theory application in the field of fire safety in construction.

The choice of methods of water treatment in conditions of increasing requirements for drinking water quality, lack of funding for the commissioning of new water supply capacities and non-decreasing anthropogenic loads on water sources, is dominant in the design of new and reconstruction of existing water treatment stations. The authors developed an electronic classifier of natural water treatment technologies for computer support of selection and feasibility study of optimal design solution of water supply on the basis of classifiers of technological schemes of water treatment, developed by the team of authors under scientific and methodological guidance of M.G. Jurba. Use of this system allows to increase efficiency of design of new water treatment stations and reconstruction of existing ones due to reduction of selection time of technological schemes, to minimize probability of selection error. It provides the best value for money for the project.

На естественное воспроизводство промысловых рыб влияют многие факторы, которые зависят от характеристики водной среды, гидрохимического и гидрологического режимов водных источников. В статье рассматриваются многолетние наблюдения по основным характеристикам водоисточника, антропогенное воздействие на р. Урал по Атырауской и Западно-Казахстанской областям в весенний, летний и осенний периоды. Ежегодно в реке Урал наблюдается колебание уровня воды в период нерестового хода рыб, сокращение сроков подъема и спада паводковых вод в период нереста производителей рыб. Наиболее низкая эффективность воспроизводства рыб наблюдалась в маловодные годы. В эти годы нерест рыб проходил в основном в русловой части реки, так как береговые нерестилища затапливались только на 50 %. В маловодные годы промысловый возврат от молоди снижался в 10 раз и меньше, таким образом в условиях Урал-Каспийского бассейна контроль за состоянием среды обитания рыб, их кормовой базы и биоресурсов является первоочередной задачей.
