Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to determine maintenance work, then the process is simple, but the accuracy of work cost and operational value assessment is insufficient
Solution Approach 1:
The analysis system is segmented into distinct functional modules: a work cost calculation unit for calculating work costs under different work items, an operational value analysis unit for analyzing operational values, and a value comparison unit for comparing results. This segmentation allows each module to specialize in specific calculations, improving overall assessment accuracy while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent introduces an intermediary analysis system that mediates between traditional maintenance planning and decision-making. The system processes work items, calculates costs, analyzes operational values, and provides comparative assessments, serving as a bridge that enhances decision accuracy without requiring complete overhaul of existing maintenance processes.
2Measurement precision
If comprehensive analysis of work cost and operational value changes is performed, then decision accuracy improves, but the analysis time and computational resources increase
Solution Approach 1:
The system performs preliminary calculations by establishing baseline work costs and operational values before comparing them with alternative work scenarios. By pre-calculating reference values and organizing data structures in advance, the system reduces the time required for comparative analysis while maintaining comprehensive assessment accuracy.
Solution Approach 2:
The patent focuses on analyzing changes in work cost and operational value parameters when work items are added or modified, rather than recalculating absolute values from scratch. This parameter change approach significantly reduces computational time and resources while maintaining the accuracy needed for informed maintenance decisions.
3Productivity
If detailed comparison of different work scenarios is conducted, then optimization capability improves, but the complexity of data processing increases
Solution Approach 1:
The analysis system is designed with universal functionality to handle various types of maintenance work items, work cost calculations, and operational value assessments through a unified framework. The work cost calculation unit, operational value analysis unit, and value comparison unit can process different maintenance scenarios using the same core methodology, improving optimization capability while avoiding the need for separate complex processing systems for each maintenance type.
