What the Data for This Category Looks Like
The business data for complete vehicle final assembly takes the Vehicle Identification Number (VIN) as the core thread. Daily documents include production orders, VIN lists, assembly work instructions, tightening data, offline inspection reports, rework records, and conformity and release documents. Data sources cover ERP/MES systems, VIN and configuration systems, supplier batch ledgers, tightening tools, EOL inspection lines, and quality traceability systems. Update frequencies are per vehicle, real-time, and per shift. Data fields include VIN codes, part numbers, torque values, inspection results, and some fields have exclusive units, such as newton meters (N·m) for torque.
Constraints Imposed on Forms and Interactions by These Characteristics
Mixed-line production centered on VIN requires forms to support bulk import of multiple VINs and precise single-item matching to prevent mismatching and missed assembly. Real-time updated tightening and inspection data requires forms to have real-time verification capabilities, to block submissions that do not meet process requirements. Supplier batch data updated per shift requires forms to quickly associate the latest batch information, to avoid using expired data. Compliance requirements for vehicle traceability require forms to record every fill and modification operation, to facilitate subsequent problem troubleshooting. High-complexity configuration matching requires interactive options in forms to be displayed in hierarchical categories, to reduce fill difficulty.
Configuration Settings
Configurations below are adapted for FastGPT v4.17.0:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
formInput Bulk Import Limit | 50 items per batch | Adapts to the batch scale of mixed-line production per shift, avoids import timeouts |
userSelect Part Classification Hierarchy | Three-level classification by assembly - component - part | Matches the configuration matching logic of VIN lists, simplifies the fill selection process |
formInput Input Format Verification | Configured according to VIN format, torque range, and part number rules | Matches the exclusive data field formats of complete vehicle final assembly, blocks invalid fills |
| Timeout Threshold | 600 seconds | Adapts to the loading and verification duration of large tender documents, calibrated based on actual testing |
| Fill Operation Logging | Enable full-process log recording | Meets compliance requirements for vehicle traceability, facilitates subsequent problem troubleshooting |
| Error Prompt Template | Bound to the business meaning of the corresponding field | Allows fill personnel to quickly locate mismatched items, such as prompts for torque values exceeding the range |
Three Common Misconfigurations
- The phenomenon where some fields are empty after importing a VIN list. The cause is that format verification rules for the corresponding fields are not configured, causing non-standard VIN codes or part numbers to not be recognized by the system.
- The phenomenon of timeout errors returned during bulk submission. The cause is that the timeout threshold is not adjusted, exceeding the system's default short duration limit, and unable to complete verification of large tender documents.
- The phenomenon of cross-level duplicate options when selecting parts. The cause is that lower-level options are not filtered by assembly hierarchy, causing redundant display of parts in mixed-line configurations.
How to Verify Correct Configuration
- Import test data of one standard VIN code and one non-standard VIN code, verify whether the system only completes normal recognition and matching for standard data.
- Submit 50 pieces of bulk import test data, confirm that there are no timeout errors during the submission process, and all data has completed verification.
- Select a certain assembly classification, check that the drop-down menu only displays part options of the corresponding level, with no cross-level redundant content.
- Modify a certain torque value to exceed the reasonable range, check whether the system pops up an error prompt corresponding to the business meaning.
