Model of process of selecting communications channel equipment in data transmission networks

A model for the selection of the different types of communications channels for data transmission networks which form the basis of their technical equ ipment is proposed. Unlike the classical models [1], the proposed approach takes into account the discrete: nature of the problem and, therefore, does not require construction of analytic relations between the desired charact eristics of the communications channels and the output indicators of the ch annel performance. An algorithm for approximate construction of the model t hat is less "sensitive" to the dimension of the problem by comparison with well-known exact methods of integer optimization is proposed, By means of t he algorithm it is possible to estimate the: error of the feasible solution .
