GENERALIZATION OF THE PROCESSING METHOD FOR THE RESULTS OF PAIRWISE COMPARISONS IN PROBLEMS GROUP CHOICE OF NETWORK DEVICES

Abstract

The article considers the problem of decision-making when choise network equipment in conditions of multi-criteria selection and group expertise, where the object of study is the process of selecting network devices, and the subject is mathematical methods for processing and reconciling matrices of pairwise comparisons. The aim of the work is to develop a generalized method for processing the results of pairwise comparisons, based on the method of pairwise comparison, which allows to increase the accuracy of the results of expertise by correcting inconsistent judgments and adaptively taking into account the competencies of each group member. The application of the proposed method allows for a well-founded selection of network devices, in particular routers, and increases the efficiency of network operation. The developed method is based on the apparatus of the pairwise comparison method, matrix theory, iterative procedures for refining the weight coefficients of compared objects, and the aggregation of individual assessments of different competencies experts into a group assessment using the weighted sum method with the use of weight coefficients of expert competence. As a result of the study, a system of criteria for selecting routers was formed, covering functional, technical, and economic aspects, and an algorithm was developed that includes a stage of iterative correction of the consistency of assessments, which ensures the accuracy of the result in the presence of conflicting assessments of individual experts. The multi-criteria problem of selecting routers is solved by the well-known method of converting criteria into constraints The scientific novelty is in the further development of methods of group decision-making theory, which allow dynamically adjusting the influence of individual experts on group assessment depending on the level of relevance of their assessments to the specifics of the network infrastructure and increasing the accuracy of the group expertise result. The practical significance of the results obtained lies in the possibility of their use for the informed selection of equipment
