Research on Optimization of Carbon Emission Reduction of Coal Supply Chain System in Iron and Steel Industry

Abstract

Abstract The steel industry is an important basic industry for the development of the national economy and national defense construction, but it is also a major source of energy consumption and environmental pollution. In particular, the carbon emissions in the process of coal combustion and steelmaking are huge. This situation urgently needs to be improved and optimized. Therefore, based on the perspective of the coal supply chain in the steel industry, this paper constructs a multi-objective planning model to achieve a balanced optimization of total economic costs and carbon emission reduction, and verifies the effectiveness of the model through specific case data. This paper sets three different emission reduction scenarios, discusses and analyzes the changes of economic total cost and carbon emission under different emission reduction scenarios, and finds that suppliers with good coal mining technology and low carbon emission factor have more opportunities to be selected and can obtain more coal market orders. At the same time, steel plants with mature processing technology and low carbon emission factor can further gain market competitive advantage and undertake more steelmaking tasks. Finally, based on results, management suggestions for coal suppliers and steel plants are provided.
