Plant Error Prioritization by Procedural Relevance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in efficiently prioritizing and addressing errors in process engineering system devices, leading to difficulties in minimizing production downtimes and restrictions, as diagnostic information is often not procedurally relevant to operators and is mainly handled by maintenance personnel.
Innovation Solution
A method where error messages from multiple system devices are transmitted to an electronic computing device, which determines the procedural relevance based on current production steps and frequency of use, allowing for dynamic prioritization and graphical representation to facilitate efficient maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diagnostic information is presented through topographical trees and message lists without procedural relevance, then all error messages are captured and transmitted, but operators and maintenance personnel cannot efficiently prioritize which errors to address first
Solution Approach 1:
The patent introduces an intermediary system (the operator station with procedural relevance evaluation) that mediates between the error messages from system devices and the operators/maintenance personnel. This intermediary automatically evaluates which errors are procedurally relevant to the current production step and presents them in a prioritized manner, eliminating the need for operators to manually sort through all errors.
Solution Approach 2:
The patent replaces the manual mechanical process of operators reviewing and prioritizing errors with an automated electronic system. The operator station automatically evaluates procedural relevance based on the current production step, substituting human judgment with automated logic that continuously monitors production status and error priority.
2Loss of information
If multiple system devices report errors simultaneously, then comprehensive error coverage is achieved, but it becomes difficult to determine which error has the greatest impact on production flow
Solution Approach 1:
The patent applies local quality by evaluating each error message individually based on its specific procedural relevance to the current production step. Instead of treating all errors uniformly, the system assigns different priority levels to different errors depending on their local impact on the ongoing production process, allowing operators to focus on the most critical errors first.
Solution Approach 2:
The patent changes the parameter of error presentation from a static list to a dynamic evaluation based on procedural relevance. The operator station continuously monitors the current production step and adjusts the priority ranking of errors accordingly, transforming the error information from a fixed state to a dynamically optimized state that reflects current production needs.
3Ease of repair
If troubleshooting begins with the least procedurally relevant errors, then all errors are addressed, but production downtime and restrictions are maximized
Solution Approach 1:
The patent performs preliminary action by pre-evaluating and prioritizing errors before operators begin troubleshooting. The operator station automatically determines which errors are most relevant to the current production step and presents them in priority order, allowing operators to address critical errors first rather than working through errors in an arbitrary or least-relevant-first sequence.
