Alarm Response Process Mapping for Critical Alarm Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alarm management systems lack the ability to track and analyze the sequence of operator actions in response to alarms, making it difficult to understand how operators respond to alarms and identify effective response processes.
Innovation Solution
The proposed method uses process mining techniques to map the alarm response process with real data, allowing for the visualization of operator actions and their relationship to specific alarms, thereby generating an alarm resolution flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional alarm management systems are used to monitor technical alarms, then alarm detection capability is maintained, but the ability to track and analyze operator response sequences is lost
Solution Approach 1:
The patent combines alarm monitoring functionality with operator action tracking into a unified system. The alarm management system integrates with the control system to automatically capture both alarm events and subsequent operator responses, eliminating the need for separate tracking mechanisms and interviews while preserving all relevant information.
Solution Approach 2:
The patent replaces manual information gathering methods (interviews, paper records) with automated electronic tracking. The system automatically logs operator actions and correlates them with alarm events through digital data processing, eliminating information loss associated with manual recording methods.
2Reliability
If multiple alarm triggers are monitored simultaneously, then comprehensive alarm coverage is achieved, but operator response effectiveness decreases due to alarm overlap
Solution Approach 1:
The patent implements feedback mechanisms that provide operators with information about their response actions and their effectiveness. The system tracks whether alarms were successfully resolved following operator actions, enabling continuous improvement of response procedures and reducing alarm overlap impacts through learned optimizations.
Solution Approach 2:
The patent segments alarm analysis by tracking individual alarm-resolution sequences separately. This allows the system to maintain comprehensive monitoring of multiple alarms while analyzing each response sequence independently, preventing operator overload by processing information in discrete, manageable units.
3Loss of information
If process mining techniques are applied to map alarm response processes, then understanding of operator responses improves, but data processing complexity increases
Solution Approach 1:
The patent enables the system to automatically perform process mining and generate process maps without requiring external analytical tools or manual intervention. The alarm management system inherently captures and processes the necessary data, performing self-analysis of response patterns and generating insights autonomously.
Solution Approach 2:
The patent creates a multi-functional system that simultaneously performs alarm monitoring, operator action tracking, data processing, and process analysis. This universal system handles multiple functions within a single integrated platform, reducing overall complexity compared to using separate specialized tools for each function.
