SCIENTIFIC AND PRACTICAL MECHANISM OF ECONOMIC EVALUATION OF THE APPLICATION OF TECHNOLOGICAL SCHEMES IN LOGISTICS MULTIMODAL SYSTEMS

The industrial sector of Russia is the most important segment of the country's economy. The modern chemical industry has well-established technologies for the production of high-quality caustic soda. Caustic soda is widely used in various production segments, including: chemistry and petrochemistry, metallurgy, gas, food, textile, pulp and paper industry. The unstable economic situation in the world has stopped the action of freight traffic flows in the logistics systems and led to an increase in prices for raw materials. Many countries have started searching for import substitution of raw materials and goods against the background of a sharp break in import supplies. The "leading chemical enterprise" in the Volgograd region is engaged in the production of chemical products. The main volumes of the company's foreign supplies accounted for Europe and Asia. The paper studies the unevenness of foreign supplies in recent years (2020-2021). The characteristic of the links of the logistics system for the transportation of chemical products along the routes "Volgograd – Bishkek" and "Volgograd – Netherlands" is obtained. The time economic costs in the links of multimodal logistics systems are calculated. International routes for the transportation of chemical products to Kyrgyzstan and the Netherlands have been compiled. The effective modes of operation of drivers of automobile transport are determined. Technological schemes for the transportation of caustic soda from Volgograd to Bishkek, using reverse loading of motor transport, have been developed, ensuring a reduction in transport costs.
