Engineering Contradiction Analysis
1Measurement precision
If conventional comparison data is used for device replacement proposals, then the proposal process is simple, but the accuracy of cost and power consumption comparisons is insufficient
Solution Approach 1:
The system segments the comparison process into distinct functional modules: a prediction part that generates operation amount predictions, a calculation part that computes indicator values, and an extraction part that identifies substitute devices. This segmentation allows each module to specialize in specific calculations, improving accuracy while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The prediction part performs preliminary calculations by generating predicted operation amounts for the target device during the prediction period. This preliminary action enables the calculation part to compute accurate indicator values (costs and power consumption) before the actual replacement decision, thereby improving comparison accuracy in advance.
2Reliability
If detailed operation amount predictions are generated, then the persuasiveness of replacement proposals improves, but the calculation time and processing load increase
Solution Approach 1:
The system changes parameters by focusing predictions on the most critical indicators (cost and power consumption) rather than computing all possible device attributes. The calculation part computes indicator values based on predicted operation amounts, transforming raw prediction data into meaningful comparison metrics that enhance persuasiveness without requiring exhaustive calculations.
Solution Approach 2:
The extraction part selectively extracts and compares only the most relevant substitute devices based on the calculated indicator values. This extraction process filters out unnecessary devices and focuses on those with the highest replacement potential, reducing the time required for comprehensive comparison while maintaining proposal reliability.
3Measurement precision
If multiple indicator values are calculated for accurate comparison, then the quality of replacement proposals improves, but the data storage and processing requirements increase
Solution Approach 1:
The system applies local quality by storing and processing detailed prediction and indicator data only for the target device and its most relevant substitutes during the prediction period. Rather than maintaining comprehensive historical data for all devices, the system focuses computational resources on generating high-quality comparison data for specific replacement scenarios, thereby improving data quality while controlling storage requirements.
