The article deals with the actual issue of improving the scientific and methodical apparatus for evaluating the effectiveness of the digital communication line. Recent researches and publications on this issue have been analyzed. The analysis shows that these methods can not provide a sufficient level of accuracy and objectivity of the assessment due to the failure to take into account the experience of using communication lines during the operation and some factors that significantly influence the efficiency of digital lines functioning in these conditions. Another methodological approach for solving the applied problem is considered in the article. The application of the method of vector estimation of the efficiency indicator is proposed. The determined integral indicator of efficiency and the criterion for evaluating the effectiveness of the digital line for solving the problem. The relationships for estimating external and internal factors and their influence on the efficiency of digital communication line operation are presented. The proposed method gives an opportunity to obtain a more objective and adequate assessment of the efficiency of the communication line. The application of this method of vector estimation of efficiency eliminates the need to solve a problematic issue, which consists in the normalization of the components of the evaluation criterion, bringing to uniform dimensions and scales, their ranking or assigning weight coefficients, and also convolutions of individual components, which makes it possible to use the method described in the article for problems evaluation of the efficiency of different kind of lines and communication networks.
