Defect and anti-measure false closed-loop judgment method and system based on planned work order

The invention discloses a defect and anti-measure false closed-loop judgment method based on a planned work order, and the method comprises the steps: receiving work order data submitted by a terminal user, and analyzing the work order data through a natural language processing technology; constructing a work order judgment model, comparing historical work order data, generating defect reports, and sorting the defect reports according to severity levels; based on the defect report, making improvement measures, and using a decision support system to optimize selection and scheduling of the measures; and updating the work order management system, carrying out deep analysis on the updated work order data, finally confirming true closing of a defect closed loop through a comprehensive evaluation module according to a deep analysis result, and generating a final report. By deeply analyzing the work order data, the accuracy and classification of problem identification are improved, historical and current data are d
