A multicriteria model of qualitative assessment and selection of modern time-domain reflectometers is proposed in the article. The purpose of this study is to accelerate the procedure of determining the best model of the reflectometer from the appropriate company by creating a criterial equation based on modeling and visualization of multi-parameter quality criteria. A relational model of a set of modern time-domain reflectometers with structured data of technical and economic indicators has been developed. Conditional dimensional criteria for determining values based on dimension theory have been compiled. A multicriteria model of qualitative assessment of modern time-domain reflectometers in dimensionless coordinates has been constructed. A comparative analysis to determine the best model of the reflectometer of a certain company by parameters has been performed. To solve this problem, a set of modern time-domain reflectometers with structured data of technical and economic parameters in the form of a relational model is defined. It is proposed to use dimensional theory, physical modeling and to create conditional quality criteria based on the heuristic method. Comparative analysis shows that Megger company is the best in terms of dimensional criteria. The histogram compares technical and economic indicators of time-domain reflectometers of this company. As can be seen from the comparison of technical and economic indicators of Megger time-domain reflectometers, Megger Teleflex VX model, which has the best range and accuracy is the best one. The developed model allows to accelerate the design process and select the way to improve and ensure high quality for devices of this type.
