Информационные технологии. 2017. Т. 23. № 9. С. 627-634.

The article deals with the stages of the decision-making process when choosing a computer networks project. The authors propose a mathematical apparatus for the evaluation of project solutions and selection of network equipment. The work considers questions of selecting the most preferred company-integrator, based on it’s assessment of the project solutions, network equipment, vendors, developers, and complex project presentation. It is shown that at the first stage (formation of the integrators list, their evaluation and ranking criteria) the use of methods based on information on allowable values, criteria: method of expanding the set of satisfactory and unsatisfactory or methods of lexicographic ordering and semi-ordering will be effective to reduce the of alternatives number. As the main method for evaluation and selection of alternative design decisions the decision maker proposes the use of the analytic hierarchy process.

The article consider the case when the decision maker can specify the relative evaluation of the alternatives, it is advisable to enlist the expert group The method of ranking alternatives is advisable to use for decision-making on integrated assessment of the project. The method of permutations is suggested for detailed consideration by experts of the projects quality offered by the integrators. The method allows project comparison on several criteria (calculation criteria weights on the basis of the procedure from the analytic hierarchy process).
