Abstract
The paper analyzes the problem of choosing an automatic control system for a road milling cutter for cold milling. The analysis of the ACS of the leading manufacturers was carried out, the typical structure of the ACS, the features of their functioning was determined, the necessity of building a selection model was substantiated, which would take into account the entire set of the main characteristics of the ACS of the road milling machine and make a scientifically grounded choice in conditions of uncertainty.
 The purpose of this work is to increase the efficiency of the use of cold milling cutters by developing a model for choosing an ACS for a road milling cutter under uncertainty. To achieve this goal, the most appropriate is the use of the Analytic Hierarchy Process (methodology) based on the decomposition of the choice problem using a hierarchical structural model. Economic criteria (cost of ACS, operating costs), technical criteria (accuracy, speed, adaptive speed control, engine control, alignment of the cutter, working out of small radii), operational criteria (reliability, diagnostics and registration, ease of installation and adjustment, external control, service) and ergonomic criteria (visualization of parameters, operator comfort) that characterize the ACS of a road milling machine. The originality consists in the construction, on the basis of these groups of criteria, of a hierarchical structural model for choosing an ACS for a road milling cutter, which makes it possible to implement an Analytic Hierarchy Process and choose a reasonable alternative. The practicalvalue lies in the fact that the use of the developed model will make it possible to carry out a scientifically grounded choice of the ACS of the road milling cutter, taking into account the entire set of economic, technical, operational and ergonomic groups of criteria. In the course of further research, the software implementation of the developed model will be carried out in the form of an expert system for choosing the ACS of a road milling machine.
