Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If process models are manually built to accurately represent manufacturing processes, then data acquisition accuracy is improved, but the complexity and time required to build and maintain the models increases significantly
Solution Approach 1:
The system automatically generates process models by copying and structuring actual site data, eliminating the need for manual model building. The process models are dynamically created from real manufacturing data, ensuring accuracy while reducing complexity.
Solution Approach 2:
The system performs self-updating by automatically detecting changes in actual site data and regenerating process models without human intervention. This self-service mechanism maintains data accuracy while eliminating the manual maintenance burden.
2Reliability
If process models are manually updated to reflect changes in work processes, then data accuracy is maintained, but the time and resources required for updates increase
Solution Approach 1:
The system continuously monitors actual site data and uses this feedback to automatically detect discrepancies between actual and master process models. This feedback loop ensures data accuracy is maintained while eliminating manual update efforts.
Solution Approach 2:
The system proactively detects changes in actual site data before they cause data acquisition errors. By performing preliminary detection and automatic model regeneration, the system maintains accuracy without requiring reactive manual updates.
3Loss of time
If automated process models are generated from actual site data, then model building time is reduced, but mismatches between actual data and models occur when work processes change
Solution Approach 1:
The system implements dynamic process models that automatically adapt to changes in actual site data. When work processes change, the system detects the changes and regenerates models in real-time, maintaining consistency between actual data and models without manual intervention.
Solution Approach 2:
The system automatically detects discrepancies between actual and master models and performs self-updating by regenerating process models from actual site data. This self-service capability ensures model reliability is maintained while keeping model building time minimal.
4Reliability
If frequent model updates are performed to match actual site changes, then data acquisition reliability is improved, but the computational resources and processing time increase
Solution Approach 1:
The system performs model updates periodically based on detected changes in actual site data rather than continuously. This periodic action approach maintains data acquisition reliability by updating models only when necessary, reducing unnecessary computational resource consumption.
Solution Approach 2:
The system uses feedback from change detection mechanisms to trigger model updates only when actual site data changes are detected. This feedback-driven approach ensures reliability is maintained while minimizing computational resource usage by avoiding unnecessary updates.
Data Source
AI summary
A process model management system includes a processor and a storage device, the storage device being configured to store actual data of tasks at a manufacturing site and master data including design information of the tasks. The processor is configured to generate an actual process model based on the actual data, generate a master process model based on the master data, generate a synthetic process model by synthesizing the actual process model and the master process model, when the actual data is changed, detect a difference of the actual process model due to the change of the actual data, when the master data is changed, detect a difference of the master process model due to the change of the master data, detect a difference of the synthetic process model due to the change of the actual data or the master data, and output a notification based on the detected difference.
