P&ID Library Generation Using LLM Annotation and Typical Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creating Piping and Instrumentation Diagrams (P&IDs) is a labor-intensive and time-consuming process due to the complexity of accurately representing process equipment and their interconnections, requiring deep understanding and multiple revisions to ensure accuracy and compliance with industry standards, and the challenge of combining standard configurations of equipment and instrumentation.
Innovation Solution
A system using Large Language Models (LLMs) to generate P&IDs from functional requirements, leveraging a database of annotated P&IDs, and employing few-shot prompting and capability matching to automate the annotation process, reducing the need for manual modeling and increasing the degree of automation.

Engineering Contradiction Analysis
1Manufacturing precision
If manual methods are used to create P&IDs, then accuracy and compliance with industry standards can be ensured through deep understanding and multiple revisions, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The system performs preliminary actions by pre-annotating P&ID databases with structured information about equipment, instruments, and connections before the actual P&ID creation process. This preprocessing enables the LLM to quickly retrieve and assemble accurate components without manual analysis during the creation phase, thus maintaining accuracy while improving productivity.
Solution Approach 2:
The system creates standardized templates and reusable components from existing annotated P&IDs in the database. These copied templates represent proven, compliant configurations that can be rapidly instantiated and modified, ensuring accuracy through replication of validated designs while dramatically reducing creation time.
2Stability of the object's composition
If companies create and maintain a database of common sub-systems (typicals) to simplify P&ID creation, then consistency and adherence to standards are improved, but identifying and combining the required sub-systems remains challenging and time-consuming
Solution Approach 1:
The LLM analyzes the process description and provides feedback about which sub-systems from the database are relevant, then iteratively refines the selection by checking against functional requirements. This feedback loop automates the complex selection process while maintaining consistency with company standards through structured querying of the annotated database.
Solution Approach 2:
The system replaces the manual mechanical process of searching, identifying, and combining sub-systems with an automated LLM-based information processing system. The LLM naturally language interface substitutes for complex search and selection mechanisms, automatically matching process requirements with appropriate sub-systems from the database.
3Extent of automation
If manual annotation of P&IDs in the database is performed, then the database can support automated P&ID generation, but tremendous efforts from domain experts are required
Solution Approach 1:
The system enables self-service annotation by using the LLM to automatically extract and annotate equipment, instruments, and connection information directly from unstructured P&ID images or existing documentation. This eliminates the need for manual expert annotation while still creating the structured database required for automated P&ID generation.
Solution Approach 2:
Manual expert annotation is replaced with automated optical character recognition (OCR) and natural language processing techniques. The LLM processes unstructured P&ID content and automatically generates structured annotations, substituting the manual mechanical annotation process with automated information extraction and classification.
