Risk early warning method and device of supply chain node and storage medium

Abstract

The application provides a supply chain node risk early warning method and device and a storage medium. The method comprises the following steps: determining a supply chain; the supply chain comprises a plurality of production nodes representing independent factories; a production prediction model is constructed for each production node in a chain mode; other production nodes having relevance with a current production node are found in the upstream of the current production node as relevant nodes; material production information of the current production node at a future time point is predicted by using the material production information of the relevant nodes at a historical time point and the future time point according to the production prediction model; a target production risk value of the production node is detected according to the geographical position of the production node and the material production information of the production node at the historical time point and the future time point; and a warning operation is performed on the production node according to the target production risk value. In this embodiment, the accumulation of uncertainty is reduced while the risk transmission is maintained, so that the early warning accuracy of the risk event is effectively improved, and the false positive rate is reduced.
