The research of software practicality of computing complexes by using expert statistical method

Мodern software is quite widely presented in various spheres of life in our country. The software is characterized by many features. If we compare the stated characteristics of software of computing complexes from different producers, the most of the elements of comparison, especially quantitative characteristics, are turned out to be quite close to each other, and the objects of comparison are almost identical. There is an urgent task to select the best object from several identical ones for further researches. This is especially actual if the comparison of the quantitative characteristics of the software does not produce the desired results. Then the problem should be solved with the help of experts to evaluate the qualitative characteristics and using the appropriate mathematical methods that justifies the scientific meaning of the chosen approach. In this work, high-quality software metrics are proposed to investigate . In particular, one of the qualitative characteristics of the software that can be evaluated by users without much difficulty is practicality. To study the characteristics and metrics of practicality, the work proposes to use expert and statistical procedures, which are combined in the expert statistical method. Questions of organization of expert survey for assessment of practical characteristics are covered, method of statistical processing of expert data is presented, procedure of selection and analysis of mathematical model of complex indicator of software practicality quality is investigated. The further development of the ideas set out in this article will be the development of software for expert and statistical procedures in assessing the quality metrics of software.
