Engineering Contradiction Analysis
1Measurement precision
If existing systems are used to optimize intermediate physical streams and units, then optimization is performed, but marginal values and shadow values are inaccurately tracked leading to inefficient optimization
Solution Approach 1:
The system segments the plant into discrete physical units and physical streams, creating a detailed flow sheet model. Each intermediate physical stream and unit is individually identified and analyzed, allowing for precise tracking of marginal and shadow values at each segment rather than treating the plant as a monolithic system.
Solution Approach 2:
The system implements feedback mechanisms by continuously calculating and updating impact value data based on changes in physical and chemical properties of intermediate streams. This feedback loop enables accurate tracking of marginal and shadow values, allowing the optimization system to respond dynamically to changes in plant operations and adjust optimization strategies accordingly.
2Manufacturing precision
If detailed analysis of intermediate physical streams is performed, then optimization accuracy is improved, but system complexity increases
Solution Approach 1:
The system introduces an intermediary computational layer that automatically calculates impact value data, marginal values, and shadow values based on the flow sheet model. This intermediary processing layer handles the complexity of detailed analysis, allowing accurate optimization without requiring the user to manually manage the computational complexity of tracking numerous intermediate stream parameters.
3Loss of information
If comprehensive impact value data is collected for all intermediate streams, then optimization decisions are more informed, but data processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing impact value data, marginal values, and shadow values in the flow sheet model before optimization decisions are required. This advance preparation ensures that comprehensive impact value information is readily available when needed, eliminating the need for time-consuming data collection and processing at the moment of decision-making.
