AI Technical Summary
In the process of multi-unit collaborative production, some production lines lack the ability to handle defects, resulting in information asymmetry, lack of state control of processes, and data dispersion when problem volumes are entrusted for processing, making it impossible to achieve full life cycle management.
The system adopts a PDCA closed-loop process design, combined with full-dimensional data binding and front-end visual filtering, to achieve full traceability and reconciliation of the problem voucher from application to final destination. It ensures data consistency through status-driven processes and automatic data comparison, and processes are handled through access control and operation traceability.
It enables full traceability and reconciliation of issue volume processing, improves processing efficiency and data management uniformity, solves the problems of information asymmetry and stateless process control, and provides a solution for rapid location and unified recording.
Abstract
Description
Technical Field
[0001] This invention relates to the field of quality control technology for metallurgical strip steel production lines, specifically to a production line that does not have its own defect handling capabilities. It entrusts problematic rolls to other units for processing such as rewinding, trimming, and recutting, and uses the PDCA cycle to achieve a closed-loop reconciliation management method for the entire process of application, processing, feedback, confirmation, and final destination determination. Background Technology
[0002] In multi-unit collaborative production processes, some production lines are only responsible for rolling or basic processing and lack the capabilities for defect handling, slitting, and cutting. When problematic coils occur, they must be outsourced to other specialized processing units. The traditional model suffers from the following pain points: 1. Entrustment without formal application, verbal communication of key information such as volume number, defects, and handling plan is prone to omission; 2. There is an information asymmetry between the client and the processing party; there are no unified records of changes in weight, surface grade, and defects before and after processing, making reconciliation difficult. 3. The processing flow lacks state control, making it impossible to quickly locate the "applied / processed / confirmed" nodes, resulting in low efficiency; 4. After the problematic volumes are processed, their final destination (downgrade, classification, reuse, storage, etc.) is not uniformly recorded and cannot be traced. 5. Data is scattered across paper or multiple systems, making it impossible to achieve full lifecycle management of problem volumes across production lines. Summary of the Invention
[0003] This invention provides a method for cross-production line issue volume delegation processing and PDCA closed-loop reconciliation management. Through state-driven processes, multi-dimensional data binding, and front-end visual filtering, it enables full traceability and reconciliation of issue volumes from application to final destination.
[0004] 3.1 PDCA Closed-Loop Process Design • Plan (Application): The production line is tasked with entering the problem roll information, including roll number, defect description, proposed processing unit, and proposed processing solution (splitting / trimming / recutting, etc.), and the application is initiated. The status is marked as "Application Completed".
[0005] • Do (Execution / Processing): The entrusted crew receives the application, enters the actual processing information, including processing date, shift, crew, actual processing plan, post-processing defects, post-processing weight, surface grade, etc., and updates the status to "Processed".
[0006] • Check (Inspection / Confirmation): The production line is tasked with verifying the processing results, confirming the consistency of data before and after processing, and updating the status to "Confirmed".
[0007] • Act (Disposal / Flow): After confirmation, the system records the final flow of the issue volume (downgrade, judgment, reuse, storage, etc.), completing the entire closed loop.
[0008] 3.2 Comprehensive Data Binding and Reconciliation Client information: Roll number, raw material information (thickness / width / weight / length), production shift / team, defect description, proposed processing unit, proposed processing plan.
[0009] • Processing information: Processing date, processing shift / team, actual processing plan, defects after processing, weight after processing, surface grade.
[0010] • Core of reconciliation: Automatically compares changes in weight, defects, and surface grade before and after processing to ensure data consistency and solve the problem of unclear reconciliation in traditional systems.
[0011] 3.3 Front-end visualization and status filtering • Color-coded status indicators: Different colors are used to visually mark process nodes: "Applied", "Processed", "Confirmed", allowing you to identify the current progress at a glance.
[0012] • One-click filtering function: Provides a status filtering button to quickly filter issue volumes with corresponding statuses, making it easier for each position to locate pending tasks and improve processing efficiency.
[0013] 3.4 Operation Tracking and Access Control • Every operation (add / modify / process / confirm / delete) records the operator, operation address, and operation time, enabling audit-level traceability.
[0014] • Access control: Only the delegating party can initiate / confirm the application, and only the entrusted party can enter and process the information, preventing unauthorized operations.
[0015] 3.5 Reports and Export • Automatically generate issue volume processing ledgers, cross-production line outsourcing statistical reports, and reconciliation reports.
[0016] • Supports one-click export to Excel for internal auditing, quality analysis, and cost accounting.
