Maintenance Permission Persistence Across System Restarts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing systems, maintenance workers need to repeatedly obtain operation permission from manager users after each restart of an information processing apparatus during maintenance, requiring unnecessary effort from both parties.
Innovation Solution
An information processing apparatus that assigns maintenance worker operation permission in advance and automatically cancels it upon completion of the maintenance work, maintaining the state of permission if the work is not finished, eliminating the need for repeated approvals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operation permission is assigned to maintenance worker before maintenance work, then productivity is improved, but security risk increases
Solution Approach 1:
The system performs preliminary action by assigning operation permission to the maintenance worker before the maintenance work begins. The manager user approves the maintenance work application in advance, and the system automatically assigns operation permission without requiring repeated approvals after restarts. This preliminary assignment of permission improves productivity while the system maintains security through automatic cancellation when work is completed.
Solution Approach 2:
The system implements feedback mechanisms to monitor the maintenance work status. The operation permission is automatically canceled when the maintenance work is completed, as detected by the system. This feedback loop ensures that permission is maintained only when necessary, balancing productivity improvement with security risk management.
2Reliability
If operation permission is reassigned after each restart, then security is maintained, but loss of time increases
Solution Approach 1:
The system performs preliminary action by assigning operation permission in advance before the maintenance work begins. The manager user approves the maintenance work application once, and the operation permission remains valid across restarts without requiring reapproval. This eliminates the time loss associated with repeated approval processes while maintaining security through automatic cancellation upon work completion.
Solution Approach 2:
The system ensures continuity of useful action by maintaining the operation permission state across restarts. Once the manager user approves the maintenance work and the system assigns operation permission, this permission persists through restarts without interruption or reapproval requirements. The permission is continuously valid until the maintenance work is completed and automatically canceled.
3Productivity
If operation permission is maintained during restart, then productivity is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically managing the operation permission state through integrated logic. The permission management function is built into the existing maintenance work management system, allowing it to automatically assign and cancel permissions based on maintenance work status without requiring separate complex permission management infrastructure. This keeps the system relatively simple while maintaining productivity improvements.

AI summary
An information processing apparatus includes a processor configured to assign a maintenance worker operation permission of a maintenance work applied for in advance for the information processing apparatus in accordance with an input received from a manager user, and after a return from a restart, cancel the operation permission in a case where the maintenance work applied for in advance is finished, and maintain a state of the assigned operation permission in a case where the maintenance work applied for in advance is not finished.
