Production Change Approval Workflow for BOM, BOP, and BOE Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of reliably reflecting changes and improvements made at the production site in the information management system, particularly in cyber-physical systems, due to the difficulty in synchronizing information between the digital management system and the physical production site.
Innovation Solution
An information management system that includes a search module to identify changes at the production site, an approval request module to seek approval from designated approvers, and an update module to reflect changes in the database upon approval, along with evaluation, simulation, and logging modules to ensure valid and timely updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If information about production site changes is directly reflected in the database, then the database information is updated quickly, but the reliability and accuracy of the information may deteriorate without proper verification
Solution Approach 1:
The system performs preliminary actions by notifying designated approvers before reflecting changes in the database. The approval process is initiated in advance, with approvers reviewing change contents (such as BOM, BOP, BOE modifications) before they are committed to the database, ensuring both timely updates and information reliability.
Solution Approach 2:
The system implements feedback mechanisms where approvers review and provide feedback on proposed changes. The notification system sends change requests to relevant approvers, who can approve or reject changes based on their expertise, creating a feedback loop that ensures information accuracy while maintaining update efficiency.
2Reliability
If an approval process is implemented for reflecting changes, then the reliability of information is improved, but the time required for information updates increases
Solution Approach 1:
The system prepares approval requests in advance and notifies approvers before changes are reflected. By initiating the approval process preliminarily and using notification systems, the system reduces the actual update time while maintaining reliability through pre-arranged approval workflows.
Solution Approach 2:
The system introduces an intermediary notification mechanism that facilitates communication between change initiators and approvers. This intermediary system streamlines the approval process by automatically notifying the right people at the right time, reducing manual coordination overhead and accelerating the overall update timeline.
3Measurement precision
If all changes are reviewed by approvers, then the accuracy of information is improved, but the complexity of the system increases
Solution Approach 1:
The system applies local quality by designating specific approvers for specific types of changes or specific database items. Rather than requiring universal approval for all changes, the system tailors the approval process to local requirements, reducing overall system complexity while maintaining necessary accuracy for each change category.
Solution Approach 2:
The system changes parameters by allowing flexible configuration of approval requirements. Different change types (BOM, BOP, BOE) can have different approval workflows, and the system can adapt approval thresholds based on the nature and impact of changes, optimizing the balance between accuracy and complexity.
4Productivity
If changes are reflected without verification, then productivity is improved, but the loss of information increases due to unnecessary or incorrect changes
Solution Approach 1:
The system implements feedback mechanisms where approvers review changes before they are reflected in the database. This feedback loop prevents unnecessary or incorrect changes from being committed, reducing information loss while maintaining high productivity through efficient approval workflows and automated notifications.

AI summary
An information management system includes a storage unit configured to store a database including a bill of materials (132), a bill of process (134), and a bill of equipment (136). Each of the bill of materials, the bill of process, and the bill of equipment includes designation (1328, 1348, 1368) of an approver for included information. An information management system includes: a search module (20) configured to search an item corresponding to a change content that is a content of a change from the database in response to generation of a change to a production site or generation of a change to be reflected in the production site, and search the approver of the searched item; an approval request module (30) configured to request the searched approver to approve the reflection of the change content in the database; and an update module (40) configured to reflect the change content in a corresponding item of the database in response to the approval from the approver.
