Manufacturing Change Approval for BOM, Process, and Equipment Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information management systems struggle to reliably reflect changes made at production sites, such as adjustments to production equipment or processes, into their databases, leading to synchronization issues between cyber-physical systems and actual production sites.
Innovation Solution
An information management system that includes a search module to identify changes, an approval request module to seek approval from designated approvers, and an update module to reflect changes in the database, along with evaluation, estimation, and simulation modules to ensure valid and effective changes, while using a secondary database for temporary changes until approval is obtained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If changes at the production site are directly reflected in the database without approval processes, then the synchronization speed between cyber-physical systems and actual production site is improved, but the reliability of information management deteriorates due to unverified changes
Solution Approach 1:
The system performs preliminary actions by notifying designated approvers of changes before they are reflected in the database. The approval process is initiated in advance, allowing verification of changes while maintaining a structured workflow that ensures reliability before synchronization is completed.
Solution Approach 2:
The system implements feedback mechanisms where approvers review and validate changes before they are committed to the database. This feedback loop ensures that only verified changes are synchronized, maintaining information reliability while still achieving timely updates through the structured approval process.
2Reliability
If an approval process is implemented for all changes, then the reliability of information management is improved, but the time required to reflect changes in the database increases
Solution Approach 1:
The system applies local quality by designating specific approvers for specific items or changes based on their expertise and authority. This targeted approach ensures that only necessary approvals are sought for each change, reducing unnecessary delays while maintaining reliability through appropriate verification.
Solution Approach 2:
The system changes parameters by allowing different approval workflows and timeframes for different types of changes. Urgent or minor changes may have expedited approval processes, while significant changes undergo more thorough review, optimizing the balance between reliability and speed for each specific case.
3Manufacturing precision
If all changes are verified and approved before implementation, then the manufacturing precision of information management is improved, but the productivity of change implementation deteriorates
Solution Approach 1:
The system performs preliminary notifications to approvers, allowing them to prepare for review in advance. This preliminary action enables a smoother approval process where approvers can gather necessary information beforehand, reducing actual approval time while maintaining thorough verification for information accuracy.
Solution Approach 2:
The system enables self-service by automatically notifying designated approvers and providing them with change details for review. Approvers can independently evaluate and approve changes through the system without requiring manual intervention for each step, maintaining information accuracy while improving implementation efficiency.

AI summary
An information management system includes a storage unit configured to store a database including a bill of materials, a bill of process, and a bill of equipment. Each of the bills includes designation of an approver for included information. An information management system includes: a search module 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 configured to request the searched approver to approve the reflection of the change content in the database; and an update module configured to reflect the change content in a corresponding item of the database in response to the approval from the approver.
