A systematic approach to the supply of non-metallic construction materials on river transportation

Abstract

n the presented study, the process of extraction and supply of non-metallic building materials on river transport is described from a systematic point of view. In the course of the study, functional and organizational models of a generalized river transport enterprise were developed for the system of extraction and supply of non-metallic building materials, as well as several organizational models of the following functional subsystems included in it: pre-production, extraction and production of non-metallic building materials, supply management, planning, logistics. Special attention is paid to the study of the pre-production stage of the logistic process of extraction and production of these materials. A systematic approach has made it possible to show that currently the weakest link in the supply of non-metallic building materials by river transport is the backward technical base of production and transshipment of non-metallic building materials. This is due to the fact that the modernization of mining equipment is hampered, on the one hand, by the practical absence of its production by domestic enterprises, and, on the other hand, by sanctions restrictions on foreign supplies. This affects the cost and quality of non-metallic construction materials supplied; environmental processes accompanying the extraction process. Additionally, the weak development of digital technologies in interaction with customers has an impact on supply management in general, and the lack of a scientifically based inventory management system in the process of year-round production and supply affects the level of service and cost of supplies.
