The invention relates to a method and a
system for generating emergency
action plan based on pre-arranged plan; the method comprises: an information recording step for receiving and storing the current affair information input by users; a pre-arranged plan extraction step for detecting at least one group of emergency pre-arranged plans matched with the current affair from a pre-arranged plan
database according to the current affair information; a pre-arranged
plan analysis step for extracting all correlated secondary and derivative affairs from an affair chain
database, searching typical cases similar to the current affair from a case
database, and correcting the at least one group of emergency pre-arranged plan to form an emergency
action plan; and a plan generation step for constantly forming a corrected emergency
action plan according to basic decision data in the current affair information, and generating a current emergency action plan according to a man-
machine interaction step. In the invention, the emergency action plans are generated to change artificial
decision process, thereby reducing the loss caused by artificial error and ensuring the safety of social public property.
