description: The work is devoted to the determination of the optimal instance of construction machines in the considered park of construction machines using mathematical models of nonlinear programming. Tasks that were solved during the research: 1. Analysis of scientific literature in the field of substantiation of the characteristics of the fleet of construction machines; 2. Formation of analytical models of the dependence of the cost of renting a unit of a copy of construction machines on the corresponding technical characteristics. 3. Development of an optimization model for substantiating the technical characteristics of a unit of a copy of construction machines as part of a technological group based on performance criteria and rental cost. 4. Development and implementation on a practical example of a methodology for substantiating the characteristics of a fleet of construction machines using analytical and optimization modeling tools. As a result of the study, practical results were obtained based on the technical characteristics and the number of construction vehicles using the developed optimization models. An analysis of the results indicates the adequacy and progress of the proposed methodology.
