Claim 0:
1. A 4-dimensional trajectory regulatory decision-making method for air traffic, comprising:
acquiring a node vector set of a target flight to obtain a target node vector set; wherein the target node vector set is determined according to a real-time knowledge graph, and the real-time knowledge graph is used to represent a relationship between flight information, air route information and air traffic control unit information related to an aircraft corresponding to the target flight during flight;
acquiring the node vector set of all historical flights simultaneously to obtain a historical node vector set; wherein the historical node vector set is determined according to a historical knowledge graph, and the historical knowledge graph is used to represent a relationship between historical flight information, historical air route information and historical air traffic control unit information related to aircraft corresponding to the historical flights during flight;
acquiring a similarity between the target node vector set and the node vector set of each historical flight in the historical node vector set to obtain a plurality of similarity data;
acquiring a similarity data which is greater than a preset data, from the plurality of similarity data to obtain a target similarity data;
acquiring a historical flight to which the target similarity data belongs to obtain a target historical flight;
acquiring a historical decision-making instruction of the target historical flight to obtain a target decision-making instruction, wherein the target decision-making instruction is used to assist in regulatory decision-making for the target flight.
