Determination of the optimal period for replacement of pipelines

The goal is to create and test an algorithm for finding places the optimal replacement of sections heating network district system maintain standard values trouble-free operation with a minimum financial costs. Methods. To carry out computer modeling, mathematical methods were used calculate flow distribution in branched looped thermal-hydraulic circuits. A systemic model indication parameters construction function costs, method determining pipelines indicator failure-free above have been developed. Results. An proposed implement principle increasing reliability networks through development network. As result using technique, schedule area under consideration over next 30 years was obtained. It shown that complex qualitative quantitative assessment efficiency allows one identify operation, which may be higher than entire period time. has established timing replacing individual due variation input network: year laying this system, calculation made, diameter pipeline its length, type location, output — costs maintaining likelihood uptime. Conclusion. Based on results obtained, comprehensive assessing cost operability recommended. improves quality management decisions ensure heat supply system. In future, it planned develop guidelines use section survivability promising schemes cities towns.
