Solution Overview
Problem
Industrial control systems face challenges in efficiently identifying and addressing deviations from optimal conditions due to incomplete process models, varying environmental factors, and lack of intuitive solutions for operators, especially those with less experience.
Innovation Solution
A guidance system that learns from experienced operators by correlating parameter data with human-machine interface (HMI) data to identify issues, track corrective actions, and provide key performance indicators (KPIs) and visualizations for future reference, enabling novice operators to address problems effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive process models are created to cover all production scenarios, then measurement precision and reliability improve, but device complexity and difficulty of manufacture increase significantly
Solution Approach 1:
The system pre-configures multiple template models covering different production scenarios (batch, continuous, discrete) with pre-defined relationships between process parameters. When a scenario is detected, the appropriate pre-configured template is selected and customized with actual process data, avoiding the need to create comprehensive models from scratch while maintaining accuracy.
Solution Approach 2:
Instead of creating a single comprehensive model covering all scenarios, the system creates specialized template models for specific production scenarios (batch processing, continuous processing, discrete manufacturing). Each template contains parameter relationships specific to that scenario type, improving measurement precision for each local context without requiring one overly complex universal model.
2Productivity
If detailed parameter monitoring and analysis systems are implemented, then productivity and operator efficiency improve, but device complexity increases
Solution Approach 1:
The system implements a universal guidance system that works across multiple production scenarios (batch, continuous, discrete) and multiple device types. A single system architecture handles parameter monitoring, anomaly detection, root cause analysis, and guidance generation for different production contexts, improving productivity without proportionally increasing complexity through standardized multi-functional components.
Solution Approach 2:
The system introduces an intermediary guidance layer between raw process data and operators. This intermediary automatically correlates parameter deviations, identifies root causes, and generates actionable guidance, reducing the complexity burden on operators while maintaining detailed monitoring capabilities. The intermediary translates complex data relationships into simple, actionable insights.
3Loss of time
If real-time data correlation and analysis capabilities are enhanced, then loss of time in identifying problems decreases, but use of energy and device complexity increase
Solution Approach 1:
The system pre-establishes correlation rules and analysis templates for common production scenarios and typical parameter relationships. When real-time monitoring detects anomalies, the system applies pre-configured analysis templates rather than performing exhaustive real-time correlation analysis, significantly reducing computational energy while maintaining fast problem identification.
Solution Approach 2:
The system implements hierarchical monitoring where only critical parameters and their immediate correlations are analyzed in real-time with high computational intensity. Less critical parameters use simpler monitoring thresholds and less frequent analysis. This partial intensive action approach reduces overall energy consumption while maintaining fast response for critical issues.
Data Source
AI summary
A guidance system of an industrial process captures process parameter data that is correlated with a human-machine interface (HMI) in order to learn how an experienced operator selects visualizations of key performance indicators (KPI) in order to take a corrective action to address an abnormal or non-optimal performance condition. Such solution learning can be invoked to recognize onset of another similar occurrence and responding by suggesting visualizations utilized by the experienced operator to diagnose the problem. Analytics can further determine which visualizations provided useful information relative to the problem. In addition, the corrective action can be suggested or automatically implemented.
