What Data for This Category Looks Like
Core data for this category comes from production and quality systems of enterprises producing coatings, resins, additives and similar products. Daily documents include batch production instructions, material feeding review forms, reaction process records, site cleaning records, inspection reports, and deviation and change notices. Data sources cover formula and process libraries, raw material batch ledgers, reactor DCS systems, weighing record systems, LIMS laboratory management systems, and warehouse inventory systems. Data updates are triggered per batch production or each key process step. Individual documents contain fields such as batch identifiers, process parameter values, material weighing values, equipment cleaning records, and inspection results. No fixed universal template exists, and adjustments are made based on the product variety being produced.
Constraints on Multi-turn Dialogue and Prompt Engineering
The multi-variety, batch-switching production characteristics of this category require multi-turn conversations to bind to process and quality data for a specific batch, to avoid mixing data across batches. Production data updated per key step must be called in process order during conversations. Prompts must clearly define the batch scope and link type for the data. Batch synthesis has a long single process cycle and multiple links. Conversation context must retain multi-step feeding, reaction, and site cleaning records to prevent key information loss from context overflow. Due to confidentiality of formula and process information, prompts must block unauthorized cross-enterprise data calls, and strictly match raw material and equipment information for the current production batch to avoid unrealistic associated recommendations.
Configuration Settings
These configurations are formulated for FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Maximum Context Length | 8000–12000 token | The total length of multi-step records for a single batch production in this category is approximately 6000–10000 token, reserving sufficient space to retain historical information for multi-turn conversations |
| Default Response Token Limit | 3000 token | Covers full explanatory requirements for single-batch feeding review and reaction judgment, avoiding truncation of critical content in short responses |
variables Binding Rule | Only bind raw material, equipment, and process variables for the current batch | Prevent cross-batch data mixing, aligning with batch-based management requirements for this category |
chatId Association Rule | Bind the unique identifier of the current production batch | Ensure conversation context only links to production and quality data for that batch |
messages History Retention Limit | First 20 conversation messages | Avoid context overflow while covering multi-step operation records and quality feedback |
| Multi-turn Dialogue Trigger Condition | Trigger in the order of process steps | Match the step-by-step operation logic of batch synthesis in this category |
Three Common Misconfigurations
- Symptom: The response token limit for some questions in conversations automatically changes to 200, resulting in overly short output. Cause: The context scope for the current batch is not clearly defined in the prompt, causing the system to trigger the short context protection mechanism.
- Symptom: Site cleaning records and inspection reports for a single batch cannot be successfully imported into the knowledge base. Cause: Documents are not categorized and labeled using the batch identifier field for this category, causing knowledge base retrieval to fail to match data for the corresponding batch.
- Symptom: Advanced orchestration nodes cannot send two messages in a single conversation. Cause: The array structure of
messagesis not configured correctly, and role and content fields are not added for each of the two messages separately.
How to Verify Proper Configuration
- Manually import the feeding review form and reaction process records for a single batch, then ask about the feeding parameters for that batch in the conversation, confirming that returned content matches the imported data.
- Initiate a multi-turn conversation, sequentially ask about requirements for different process steps, confirming that the system associates document information for the corresponding steps in order.
- Check the
chatIdbinding identifier, confirming that the conversation context only displays relevant data for the current production batch, with no irrelevant cross-batch content. - Test questions of varying complexity, confirming that the response token limit remains stable at the preset value and no automatic reduction occurs.
