Rule-based autocorrection of Piping and Instrumentation Diagrams (P&IDs) on graphs
TL;DR
Chemical engineers face a significant challenge in manually reviewing piping and instrumentation diagrams (P&IDs) for errors due to the large volume of documents. A rule-based method utilizing graph representations of P&IDs was developed to automate error detection and correction.
✦ Why It Matters
Engineers can leverage this rule-based method to significantly reduce the time spent on P&ID error checking.
Key Takeaways
- Utilize the pyDEXPI package for P&ID graph generation.
- Apply the 33 developed rules for error detection.
- Reduce manual review workload significantly.
- Enhance accuracy in P&ID revisions.
How It Works
The method employs a graph-based representation of P&IDs, allowing for the application of predefined rules to identify and correct errors automatically. By converting P&IDs into a structured graph format, the system can analyze connections and components systematically, applying the 33 rules derived from chemical engineering knowledge to ensure compliance and accuracy.
