Description

Technical Field

[0001] The present invention relates to the technical field of automobile raw material emission reduction, and in particular to a method and an evaluation system for collaboratively optimizing carbon emissions and costs of automobile steel materials. Background Art

[0002] Under the background of "dual carbon", carbon reduction in the automotive industry is imminent. The low-carbon development of automotive steel materials is an important way to reduce carbon in the entire life cycle of the automotive industry. The coordinated carbon reduction between the automotive industry and upstream and downstream industries has gradually become a consensus. Carry out carbon emissions and production and operation cost accounting for typical automotive steel materials from raw material production, vehicle manufacturing, use to scrapping, introduce a technical information base for carbon emission reduction of automotive steel materials throughout the life cycle, and intelligently form the optimal comprehensive cost plan through system optimization methods. Combined with advanced digital technology, develop an automotive steel material evaluation visualization system with an open data collection interface and guaranteed data security, which can effectively improve the evaluation and management level of automotive companies on upstream steel raw material suppliers, help the automotive industry achieve carbon reduction throughout the entire process, and help the country achieve the "dual carbon" goal as soon as possible.

[0003] The Chinese patent "CN116402235A A method for calculating carbon emissions throughout the life cycle of a whole vehicle" provides a method for calculating carbon emissions throughout the life cycle of a whole vehicle. This patent calculates the total ecological carbon emissions and economic costs of a single vehicle throughout its life cycle, and establishes carbon economic indicators to achieve the correlation between carbon emissions and economic costs. It conducts differentiated accounting for each technical route and provides reference opinions for the low-carbon development of the automotive industry.

[0004] However, existing methods mainly focus on carbon emissions and cost accounting during the production and use stages of automobiles, or stay at the level of accounting for carbon emissions and economic costs throughout the entire life cycle, lacking the coordinated accounting, analysis and management of carbon emissions and costs. For example, the comprehensive cost optimization method in the present invention considers application decision variables such as carbon emission reduction technology and real-time carbon prices, and systematically optimizes the optimal emission reduction plan and comprehensive cost value for automobile steel materials. In addition, existing evaluation tools often lack comprehensiveness and real-time performance, such as the lack of analysis of the comprehensive cost of automobile steel products under the influence of real-time carbon prices, and cannot provide timely decision support for the automotive industry.
