AI Technical Summary

⚠Technical Problem

Existing technologies suffer from problems in carbon emission accounting during the construction period of highways in plateau and mountainous areas, such as ambiguous boundaries, neglect of network topology characteristics, reliance on static factors leading to low accounting accuracy, inaccurate identification of emission reduction targets, and insufficient targeted measures.

⚗Method used

By acquiring and preprocessing multi-source datasets, a supply chain network-graph theory fusion model is constructed. A multi-dimensional accounting method is used to calculate the carbon emissions of the entire chain. Combined with network analysis algorithms, key carbon emission nodes and key poor paths are identified, and a three-level differentiated emission reduction optimization strategy of nodes-paths-network is generated.
