The System Dynamics Model and Simulation Analysis of Iron and Steel Supply Chain Carbon Emissions

Abstract

This paper built the iron and steel supply chain system dynamics model of carbon emissions with an in-depth analysis on the iron and steel supply chain system causality, and simulated the effects of three parameters on the iron and steel supply chain total carbon emissions, which are tons of steel production of carbon emissions, units purchasing carbon emissions and procurement cycle. The study shows that: with the increase of tons of steel production of carbon emissions and units purchasing carbon emissions, supply chain total carbon emissions increase correspondingly, and the effect is very obvious. While procurement cycle has certain influence on supply chain total carbon emissions, but the effect is not obvious; Finally, the paper put forward carbon emission control suggestions from three aspects: the introduction of relevant technologies and equipment to reduce tons of steel production of carbon emissions, optimizing logistics processes to reduce units purchasing carbon emissions, and arranging reasonable procurement cycle to optimize inventory levels.
