Tracing of large branched pipeline hydraulic networks of high optimality rank with graph presentation

The paper deals with a tracing technique for large branched pipeline hydraulic networks of the high optimality rank. The novelty of the method is that while increasing the optimization rank of the designed networks, the redundant graph of possible connections between nodes is dynamically reduced. In this case, the redundant graph of the follow-up rank is formed from previous networks rank. The method provides a computer solution to the problem of tracing of large networks containing more than one hundred nodes of the seventh optimality rank. The system is developed for large pipeline networks design of regional and interregional pipe distribution network (PDN) for irrigation purpose.
