Production Line Event Routing for Balanced Operator Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In production line monitoring systems, when multiple operators receive emails about stopped production devices, it leads to uneven operator placement and delayed maintenance, reducing the operational rate of production devices.
Innovation Solution
A production line monitoring system with a server communicating via a wireless network to terminals, processing operation information, generating event information, and transmitting it to specific terminals based on defined criteria, allowing efficient allocation of maintenance tasks.

Engineering Contradiction Analysis
1Reliability
If event information is transmitted to multiple terminals, then more operators can respond to the stopped production device, but operator placement becomes uneven and maintenance work is delayed
Solution Approach 1:
The system transmits event information selectively to specific terminals based on their proximity to the stopped production device. The server determines which operators are located near the affected device and sends notifications only to those terminals, ensuring that maintenance personnel are locally positioned for effective response while avoiding the problem of uneven operator distribution across the facility.
Solution Approach 2:
The system pre-positions operators by transmitting event information to terminals of operators who are already near the stopped production device. This preliminary action of notifying the right personnel in advance allows for immediate maintenance response without requiring operators to travel across the facility, thereby maintaining high operational rates.
2Ease of operation
If operators are notified via email, then operators can respond to stopped devices, but multiple operators may converge on the same device causing uneven placement
Solution Approach 1:
The system incorporates feedback mechanisms where the server receives information about operator locations and production device statuses, then uses this feedback to intelligently determine which terminals should receive event information. This feedback loop ensures that notifications are sent to the most appropriate operators based on real-time conditions, preventing unnecessary operator convergence and optimizing maintenance timing.
Solution Approach 2:
The system dynamically adjusts notification targets based on changing conditions such as operator locations and device statuses. Rather than using a static notification approach, the server continuously evaluates current system state and adapts which terminals receive event information, ensuring optimal maintenance response timing while preventing operator扎堆 (clustering).

AI summary
A production line monitoring system for monitoring a production line including a plurality of production devices is provided. The production line monitoring system includes: a plurality of terminals attached to a plurality of workers; and a server configured to communicate with the plurality of terminals via a wireless network. The server performs processing of receiving operation information about the production device and generating event information based on the operation information, processing of transmitting the event information to a first terminal and a second terminal of the plurality of terminals, and processing of transmitting event stop information to the second terminal when receiving response information transmitted from the first terminal after performing the processing of transmitting the event information.
