OPTIMAL CHOICE OF ELECTRONIC THEODOLITE FOR HIGHWAY CONSTRUCTION
DOI: 10.33868/0365-8392-2026-1-286-24-32
Abstract. In order to optimize engineering and surveying support for the building and repair of motorways and roads, it is proposed to use the latest surveying instruments and technologies, the effective use of which often depends on choosing the best available option based on an assessment of their technical and economic characteristics. The use of new instruments and technologies makes it possible to significantly expand the range of tasks, speed and accuracy of their implementation, and increase the availability of topographic and geodetic materials when developing project documentation.
The article is devoted to the analysis of the current state of development of the electronic theodolite market, the study of their main characteristics and features of application. Among the characteristics considered are multiplicity of magnification, battery life, dust and moisture protection, angular measurement accuracy, liquid crystal display characteristics, weight, cost (price) of the device, and warranty period. The task of selecting the best theodolite (as a management decision) is formulated based on the use of T. Saaty’s Analytic Hierarchy Process. The issue of expert assessment of criteria is discussed. The main stages of solving the problem are presented. A reasonable approach to evaluating individual criteria in the case of conflicting information about them is justified. The practical use of the hierarchy analysis method is illustrated by the problem of evaluating the technical level of some models of electronic theodolites. It is proposed to take into account, as additional criteria, the specifics of working with other systems, the nature and causes of possible errors during measurements, contradictory and incomplete information regarding the measuring devices under consideration.
Keywords: electronic theodolites, hierarchy analysis method, optimization criteria and alternatives, normalized vectors of local priorities of criteria and alternatives, assessment of the technical level of electronic theodolites.
