1Productivity
If manual processes are used for damage assessment, then device complexity is reduced, but productivity and measurement precision deteriorate
Solution Approach 1:
The patent replaces manual damage assessment processes with an automated machine learning-based system. The system uses algorithms (such as random forests, neural networks, or support vector machines) to automatically analyze building characteristics, earthquake parameters, and structural data to predict damage levels, eliminating the need for manual inspection and significantly improving assessment speed and consistency.
Solution Approach 2:
The system creates a virtual model of the physical assessment process by using machine learning algorithms that replicate and extend human expert judgment. The algorithm learns from training data containing building characteristics, earthquake parameters, and actual damage outcomes to produce predictions that mirror and surpass manual assessment capabilities.
2Measurement precision
If real-time data processing is implemented, then measurement precision and reliability are improved, but device complexity and loss of time increase
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing building characteristics, structural data, and earthquake parameters in databases before actual damage assessment is needed. The machine learning models are trained in advance on historical data, allowing them to make rapid, accurate predictions during actual earthquake events without requiring complex real-time computations.
Solution Approach 2:
The patent replaces complex real-time manual analysis with automated machine learning algorithms that can rapidly process data and produce accurate damage predictions. The system uses algorithms such as random forests, neural networks, or support vector machines that efficiently handle large datasets and provide precise results in real-time.
3Measurement precision
If comprehensive feature analysis is performed, then measurement precision is improved, but device complexity and processing time increase
Solution Approach 1:
The system performs preliminary action by pre-identifying and storing relevant building features and earthquake parameters in structured databases. The machine learning models are pre-configured with the most predictive features (such as building age, construction material, structural type, and earthquake intensity), allowing rapid retrieval and analysis during actual assessment without time-consuming feature selection processes.
Solution Approach 2:
The patent applies parameter changes by transforming complex structural and earthquake data into standardized numerical parameters that machine learning algorithms can process efficiently. The system converts qualitative building characteristics into quantitative features and normalizes earthquake parameters, enabling fast computation while maintaining assessment accuracy.
