Deployment and Upgrade for GMP-Compliant R&D Document

Data Characteristics for This Category

GMP-compliant R&D documents cover the entire drug production and quality management lifecycle. This includes batch production records, inspection records, validation protocols and reports, deviation handling reports, change control documents, and Standard Operating Procedures (SOPs). These documents typically exist as PDFs, Word files, or scanned images. They contain a mix of structured and unstructured information. Data sources primarily include internal production management systems, Laboratory Information Management Systems (LIMS), and manual entries. Document update frequencies vary. SOPs and batch records might update per batch or annually, while validation reports and deviation handling reports are event-triggered. Document structures often follow strict industry regulations. For example, batch production records include fixed fields like "Material Batch Number," "Production Batch Number," "Operator," "Start Time," and "End Time," but specific descriptions are free text. Units involve various physical quantities such as "mg," "mL," "℃," and "Pa," often with specific testing methods and limit requirements.

Constraints Imposed by These Characteristics on "Deployment and Upgrade"

The strict structure and extensive semi-structured content of GMP-compliant documents require parsing models with high-precision entity recognition and relationship extraction capabilities. This ensures accurate extraction of compliance-critical fields. The event-driven nature of document updates means the system needs to support incremental updates and version management, not just full overwrites. The prevalence of PDFs and scanned images challenges Optical Character Recognition (OCR) accuracy and multi-format processing capabilities. The presence of physical quantity units and limit values requires parsing results to distinguish between numerical values and units, and to support subsequent validation logic. Furthermore, compliance requirements make data security and audit trails critical deployment considerations, necessitating strict access control and operational log recording. For FastGPT, this means fine-tuning model selection, data preprocessing workflows, vector store configuration, and permission management.

Configuration Settings

Configuration Item	Recommended Value	Rationale for This Value
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	GMP documents often contain many images and charts, leading to larger file sizes, requiring a higher upload limit.
`maxContext`	`1500 characters`	Individual paragraphs or clauses in GMP documents can be long, requiring sufficient context to capture complete semantics.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Processing complex scanned PDFs and performing OCR takes considerable time; this avoids parsing timeouts.
`Chunk size`	`800 characters`	Balances the integrity of long paragraphs with vector retrieval efficiency, avoiding excessive fragmentation or loss of detail in large chunks.
`Recall count`	`Top 10 entries`	Increases the recall rate of relevant information, covering more potential compliance clauses or batch record details.
`Similarity threshold`	`0.75`	Ensures the precision of recalled content, preventing irrelevant or low-relevance compliance text from interfering with judgment.

Three Common Mistakes

Key fields (e.g., "Batch Number," "Test Result") in parsing results are empty or incorrectly formatted. This occurs due to OCR errors or named entity recognition models not fine-tuned for specific terminology.
After a document update, old version information is still recalled, leading to incorrect compliance judgments. This happens when version control or incremental update mechanisms are not configured.
Processing large batch production record PDF files results in 404 no body or parsing timeouts. This might be due to insufficient resource limits for the FastGPT container or PARSE_FILE_TIMEOUT_SECONDS being set too low.

How to Verify Correct Configuration

Select a test set containing various document types (SOPs, batch records, validation reports). Upload them and check the extraction accuracy of key fields (e.g., "Material Batch Number," "Inspection Method," "Limit"). Ensure it meets predefined compliance standards.
Simulate a document version update scenario. Upload a new version of an SOP file, then query related clauses. Verify the system prioritizes recalling the latest version content.
Use test documents with complex tables and scanned images for parsing. Monitor fastgpt logs to confirm no parsing failures or timeouts occur. Check the completeness of the parsed text content.
