1 results about "Trajectory pattern" patented technology

This invention belongs to the field of engineering progress diagnosis technology, specifically disclosing a method and system for diagnosing engineering construction progress deviations based on cluster analysis. The method includes: slicing the original progress data of the target project into time-series states to obtain a continuous progress state sequence; measuring the similarity of the evolution trajectory of the continuous progress state sequence and performing topological mapping on the measurement results to obtain a trajectory similarity matrix; based on the trajectory similarity matrix, performing trajectory pattern clustering on the continuous progress state sequence to obtain progress state trajectory clusters; locating key turning points in the evolution trajectory to obtain state transition points; performing critical condition backtracking on the state transition points to obtain preconditions, and performing correlation mining on the preconditions to obtain common conditions; and based on the common conditions, performing predictive risk analysis on the target project to obtain deviation diagnosis results. This invention can improve diagnostic efficiency and decision support capabilities.
