Purpose. Development of an adaptive economic and mathematical model of raw material supply management for the production activities of industrial enterprises. Methodology. In the course of the study, the following methods of understanding economic phenomena and processes were used to solve the problems posed in the work: system analysis, economic and mathematical modeling, abstract-logical and graphical methods. Findings. The work identifies specific characteristics of the organization of supply of raw materials, equipment, inventory and finished products to industrial enterprises. An adaptive economic and mathematical model of optimization of material and technical supply of these enterprises is formulated. The proposed model simplifies the choice of raw material inventory management system depending on the specifics of the production process of a particular enterprise and the external conditions of its operation. The use of adaptive model is necessary in the formation of supply and demand change programs in the markets of finished products, monitoring the movement of own funds in the organization of transportation of raw materials from suppliers and redistribution of available financial resources to address the priorities of business entities. Originality. The authors propose an adaptive economic and mathematical model for optimizing material and technical supply, which takes into account the possibility of violation of the delivery time of inventory items under the influence of force majeure, and also determines the optimal amount of raw materials for supply under certain operating conditions of a particular industrial enterprise. Practical value. The use of the economic and mathematical model formed by the authors in the economic activity of industrial enterprises will allow the latter to timely forecast and plan their logistics costs and, as a consequence, avoid irrational spending of available financial resources.

“…The energy management strategies are proposed for heavy-duty fuel cell hybrid electric vehicles (Rudolf et al, 2021). For high energy-consuming mining enterprises, the system-dynamic simulation of logistics system has been studied to meet the needs of coal transportation (Mishkurov et al, 2021). Compared with the above-mentioned transportation fuel, substituting diesel with hydrogen is regarded as an effective way to reduce the air pollution and greenhouse gas emissions of heavy trucks (Lao et al, 2020).…”

Integrated Energy System Optimal Operation in Coal District With Hydrogen Heavy Trucks

et al. 2021

The coal industry contributes significantly to the social economy, but the emission of greenhouse gases puts huge pressure on the environment in the process of mining, transportation, and power generation. In the integrated energy system (IES), the current research about the power-to-gas (P2G) technology mainly focuses on the injection of hydrogen generated from renewable energy electrolyzed water into natural gas pipelines, which may cause hydrogen embrittlement of the pipeline and cannot be repaired. In this paper, sufficient hydrogen energy can be produced through P2G technology and coal-to-hydrogen (C2H) of coal gasification, considering the typical scenario of coal district is rich in coal and renewable energy. In order to transport the mined coal to the destination, hydrogen heavy trucks have a broad space for development, which can absorb hydrogen energy in time and avoid potentially dangerous hydrogen injection into pipelines and relatively expensive hydrogen storage. An optimized scheduling model of electric-gas IES is proposed based on second-order cone programming (SOCP). In the model proposed above, the closed industrial loop (including coal mining, hydrogen production, truck transportation of coal, and integrated energy systems) has been innovatively studied, to consume renewable energy and coordinate multi-energy. Finally, an electric-gas IES study case constructed by IEEE 30-node power system and Belgium 24-node natural gas network was used to analyze. The results show that by introducing the proposed hydrogen production technology, typical daily operating costs are effectively reduced by 7.7%. Under China’s carbon emissions trading system, the operating costs of hydrogen heavy trucks have been reduced by 0.95 and 4.68% respectively, compared with electric vehicles and diesel trucks. Under Europe’s stricter carbon emissions trading system, the percentages of cost reduction are 2.56 and 9.12%, respectively. The above technical results verify the feasibility, economy, low carbon, and effectiveness of the proposed mechanism.
