The purpose of the article is modeling the efficiency system assessment of network infrastructure subsystems development and identifying their natural monopoly properties. Methods and models of natural monopoly theory, nonlinear network transport projection and variation analysis are used. The spectrum of models for identifying the natural monopoly properties of the network transport infrastructure, corresponding to changes in the parameters of the total cost functions, has been researched. Applying to modeling the development of fragments of regional transport network, computational algorithms for efficiency system assessment have been elaborated. The influence of the effect of natural monopoly synergy as the sphere of positive values of the economy of scope based on subadditivity testing for cost function has been specified. The results of calculations are presented related both specifying the assessment methodology under diagnostics of natural monopoly properties (primarily using special extensions of algorithms for finding the optimal transportation technology), and with modifications of computational experiments and quantitative assessment with variations of the factors.
