A digital twin-based park management method

Abstract

This invention discloses a park management method based on digital twins, specifically relating to the field of park operations. It addresses the problem of unstable chaining of multi-source events under conditions of reporting delays and evidence gaps, leading to inaccurate handling triggers. The method includes: event pool registration to generate event numbers and write the arrival time to the platform; anchor event filtering and mapping to park object identifiers and process stage identifiers to generate management tokens; event chain construction based on the event chain rule table to verify the stage order and evidence item requirements and generate a conflict point list; a delay profile library to generate source time credibility markers and form a reverse-order violation spectrum; a digital twin object relationship graph to form influence domain span markers; a receipt closure table to obtain the handling convergence guarantee level; a cost-sensitive decision tree to output handling template identifiers; a handling template table to generate management action instructions and trigger credentials and record instruction acceptance identifiers; and receipt comparison to freeze abnormal management tokens and update the event chain rule table and delay profile library.
