Rule-based autocorrection of Piping and Instrumentation Diagrams (P&IDs) on graphs
Researchers have developed a novel rule-based method to automatically detect and correct errors in Piping and Instrumentation Diagrams (P&IDs), which are crucial documents in chemical process engineering. The system represents P&IDs as graphs and applies rule graphs to identify and fix discrepancies, significantly reducing the manual workload associated with reviewing hundreds or thousands of pages. A case study demonstrated the method's reliability and effectiveness, utilizing 33 developed rules and the pyDEXPI Python package for P&ID graph generation. AI
