Abstract

Relevance The development of the region is reflected in its socio-economic policy and depends on the projected gross domestic product growth data, which affects the increase in freight traffic by road. In the Republic of Bashkortostan, by 2030, the volume of such traffic may grow by 30–40 %, while the number of freight transport will double. The number of personal vehicles of the population of the region will reach the level of 300–350 vehicles per 1000 inhabitants. All these data will certainly lead to an increase in the intensity and density of traffic on transport arteries, both regional and inter-municipal significance by 30–40 %. Already today, about 80 % of the length of transport arteries of regional municipal significance need to increase the strength indicators due to the accelerated wear of the roadway and a decrease in the service life between scheduled repairs. In the course of the implementation of the national project of the Russian Federation «Safe High-Quality Roads», the capacity of highways in the republic is insufficient, and the quality of highways requires an increase in strength characteristics. Therefore, the development of new approaches to the functioning of information systems is becoming in demand and makes it possible to simulate the interaction of subsystems of an automated control system (ACS): ACS for supplying mineral materials and ACS with sand and crushed stone bins will allow us to assess the complexity of organizing the interaction of ACS subsystems. The foregoing sets the task of improving the quality of the asphalt concrete mixture at the output of the asphalt concrete plant, which is ensured by the automation of the enterprise. Therefore, the task of developing a distributed hierarchical control system for information systems of the asphalt concrete plant is urgent. Aim of the research Creation of a methodological basis for the development of structures for modern management systems for the production of asphalt concrete mix. Research methods The research is based on a set of methods of the theory of probability and mathematical statistics, optimal systems and mathematical modeling, as well as the theory of automatic control. Modeling of the technological process and system analysis was carried out using the MatLab package. Results The solution of problems of digital control of asphalt concrete production in the form of a generalized approach is presented. All data on raw materials and technological process are collected in a single database, which allows them to be processed at a new level. The result of the research carried out makes it possible to apply the proposed concept and methodology to further research, which will lead to the development of the optimal structure of the ACS in the construction industry. The introduction of new research results will improve the assessment of the effectiveness of solutions for the technical re-equipment of asphalt concrete plants ACS.
