The Balance and Optimization Model of Coal Supply in the Flow Representation of Domestic Production and Imports: The Ukrainian Case Study

The successful supply of an economy with coal fuel, for a country that carries out its large-scale extraction and import, is complex production logistics problem. Violations the usual scheme in conditions crises energy markets, international conflicts, etc., lead to problem simultaneous restructuring entire scheme. This requires changes directions capacities domestic imports. In this article, above solved by economic mathematical model type. developed includes subsystems import supply. results modeling thermal different values demand are given. was used determine amounts Ukraine structure industry 2021 under condition anthracite consumers’ transformation high volatile coal. Simulations have shown eliminating use modernization existing mines. Under those conditions, will amount 3.751 million tons 2030 11.8 2035. coking imports be 5.46 tons, 5.151 7.377 2025, 2030, 2035, respectively.
