THE SELECTION OF RESERVED STRUCTURE AND THE CREATION OF THE FUNCTION FOR RELIABILITY
The determining of reliability of water systems is introduced, is derived formulas for
definition the reliability of some water pipe structures and is made the comparative analysis of
reliability and topology of these structures. The engineering method of analysis the reliability
of tracing the cyclical water pipe systems is developed, which is allowed to select a structure of
network with maximum reliability, is defined the limit reliability of area of network, is
identified that areas which would increase the reliability of the structure during its
development. The method of graph–analytic formation of tracing the new circular water pipe
system was developed ed, which would given the opportunity to build a number of competitive
options for trace circular water network and choose the best for reliability.
Keywords: the reliability of the network structure, the topology, the boundary reliability
