Construction of the Current Steiner Network of the Second Optimality Rank.

Mathematical models and the rank optimization method for current Steiner networks are presented in the work. This method is based on the nonlocal minimum condition and on the dynamical decomposition of the current Steiner network in optimized intersecting subnetworks of an equal dimension that follows from it. A computer simulation is presented that shows a sufficient effectiveness of the method in applying it in designing distributive piping networks of water- and gas-supply. [ABSTRACT FROM AUTHOR]
