Board Production Alert Escalation for Faster Error Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current board production management systems face challenges in effectively notifying operators of error causes, leading to delays in countermeasures, especially when low-skilled operators are involved or notifications are missed due to busy schedules, resulting in prolonged production interruptions.
Innovation Solution
A board production management device and method that escalate notifications by increasing the authority level or number of notifyees and the complexity of countermeasures after a specified time has elapsed, ensuring that error causes requiring manual intervention are addressed quickly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If notification is issued to low-skilled operators or operators with limited authority, then notification simplicity is maintained, but resolution speed and effectiveness deteriorate due to lack of expertise or authorization
Solution Approach 1:
The notification system dynamically adjusts the notifyee's authority level based on the error cause type and elapsed time. When an error occurs, the system initially notifies operators with basic authority, and if unresolved within a specified time, automatically escalates to operators with higher authority levels, enabling appropriate personnel to respond effectively without manual intervention
Solution Approach 2:
The system changes the parameter of operator authority level in the notification process. By varying the authority level parameter based on error characteristics and time elapsed, the system ensures that the right level of expertise is engaged for each situation, resolving the contradiction between simple notification and effective resolution
2Loss of information
If notification is issued to a specific operator, then notification precision is maintained, but notification reliability deteriorates when the operator is busy or unavailable
Solution Approach 1:
The notification system is designed to notify multiple operators with different authority levels for the same error cause. This multi-functionality ensures that if the primary operator is unavailable, alternative operators can still receive and act on the notification, maintaining both precision and reliability
Solution Approach 2:
The system implements feedback through automatic escalation based on whether the error is resolved within a specified time. If no resolution feedback is received, the system automatically notifies operators with higher authority levels, ensuring reliable delivery of critical notifications
3Reliability
If re-notification is issued after specified time elapsed, then alarm overlooking is prevented, but production downtime increases when errors require complex countermeasures
Solution Approach 1:
The notification system dynamically escalates to operators with higher authority levels based on the elapsed time and error type, rather than simply re-notifying the same operator. This dynamic adjustment prevents alarm overlooking while minimizing downtime by engaging appropriately skilled personnel from the outset
Solution Approach 2:
The system performs preliminary action by pre-defining escalation paths and authority levels for different error causes. When an error occurs, the appropriate escalation sequence is automatically executed, preventing the need for repeated notifications and reducing overall resolution time
4Productivity
If notification is escalated to operators with higher authority level, then resolution effectiveness is improved, but notification complexity increases
Solution Approach 1:
The notification system is segmented into distinct authority levels and error cause categories. Each segment has predefined notification rules, simplifying the overall system design while enabling effective escalation. The segmentation allows complex escalation logic to be managed through modular, rule-based segments rather than a monolithic complex system

AI summary
A board production management device (1) configured to manage a board production line (2), including: an initial notification section (51) configured to issue notification information including at least one of a contents of an error cause or a contents of countermeasures to a notifyee when the error cause that requires countermeasures occurs at the board production line; and an escalation notification section (52) configured to issue the notification information after escalating at least one of the notifyee or the contents of the countermeasures in a case in which the error cause is not resolved after a specified time (T1) has elapsed since the error cause occurred. Accordingly, because when the specified time has elapsed, a notification is issued as escalating the notifyee or escalating the contents of countermeasures to resolve error causes more effectively, and compared to conventional technology in which only re-notification of the occurrence of the error cause is performed, notification is performed more efficiently, enabling an error cause that requires countermeasures to be resolved more quickly.
