Все эти свойства приводят к практически полному отсутствию адаптационных механизмов для оптимизации условий эксплуатации данных систем. Причиной нарушения водоснабжения являются непредсказуемость развития систем и отсутствие алгоритмов определения вероятности миграции населения, уровня удельного водопотребления и аварийности. К ярким примерам таких ошибок можно отнести групповые водопроводы, построенные более 60 лет назад. В связи с оттоком населения и индустриализацией большое количество водопроводов продолжает оставаться «в земле», но не эксплуатируются, так как нет потребителей. Одновременно с этим существуют перегруженные системы больших городов и мегаполисов из-за активной точечной застройки, приводящей к несбалансированности инженерных систем. Парадоксально, но статистика за последние 20 лет показывает понижение уровня удельного водопотребления почти в два раза.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Предлагается при разработке перспективных схем водоснабжения учитывать неопределенность потребления воды, удельную стоимость электроэнергии в будущих периодах строительства систем водоснабжения и выбирать траектории их развития с минимальными экономическими и технологическими рисками.</p></sec><sec><title>Результаты</title><p>Результаты. С помощью составления матрицы критериев принятия решения можно выбрать параметры перспективной системы водоснабжения в условиях неопределенности численности населения, удельных нагрузок водоснабжения, удельной стоимости электроэнергии и др.</p></sec><sec><title>Выводы</title><p>Выводы. Следует переходить к многовариантному проектированию и рассматривать водопотребление, численность населения, стоимость электроэнергии как нечеткие и неопределенные значения и выбирать из них те, которые обеспечивают минимальные риски по стоимости их жизненного цикла.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Water supply systems are strategically important, energy-intensive, capital-intensive, and highly inertial systems. These characteristics result in a virtually complete lack of adaptive mechanisms for optimizing their operating conditions. Water supply disruptions are caused by the unpredictability of system development patterns and by the lack of algorithms for determining the probability of population migration tracks, specific water consumption and system failure rates. Demonstrative examples of such errors include group water supply systems built more than 60 years ago. Due to population outflow and industrial decline, many water supply systems remain underground but are no longer operated because of insufficient consumer demand. At the same time, systems in large cities and megalopolises are overloaded because of active infill development, which causes imbalances in utility networks. Paradoxically, statistics for the past 20 years show that specific water consumption has decreased by almost half.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. When designing advanced water supply schemes, uncertainties related to future water demand and electricity unit costs should be considered, and system development trajectories that minimize economic and technological risks should be selected.</p></sec><sec><title>Results</title><p>Results. A decision-making criteria matrix can be applied to select the parameters of a future water supply system under conditions of uncertainty related to population size, unit water demand, electricity costs, and other factors.</p></sec><sec><title>Conclusions</title><p>Conclusions. A multivariant design approach should be adopted, treating water consumption, population size, and electricity cost as fuzzy and uncertain variables and selecting options that minimize life-cycle cost risks.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>системы подачи и распределения воды</kwd><kwd>неопределенность в численности населения и водопотребления</kwd><kwd>выбор предпочтительного варианта строительства и реконструкции систем водоснабжения</kwd><kwd>матрица рисков</kwd><kwd>стоимость жизненного цикла</kwd><kwd>критерии принятия решения</kwd><kwd>водопроводные системы</kwd><kwd>эксплуатация и проектирование водопроводных систем</kwd><kwd>удельное водопотребление</kwd><kwd>электропотребление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>water supply and distribution systems</kwd><kwd>uncertainty in population size and water consumption</kwd><kwd>selection of the preferred option for construction and reconstruction of water supply systems</kwd><kwd>risk matrix</kwd><kwd>life-cycle cost</kwd><kwd>decision-making criteria</kwd><kwd>water supply networks</kwd><kwd>operation and design of water supply systems</kwd><kwd>specific water consumption</kwd><kwd>electricity consumption</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Чупин Р.В., Примин О.Г.
