1Measurement precision
If manual division of objects into subsystems is performed for acoustic analysis modeling, then modeling accuracy is improved, but working time and complexity increase significantly
Solution Approach 1:
The system enables automatic self-service modeling where the computational system autonomously divides the object into subsystems, determines element affiliations, and generates spatial models without requiring manual intervention. This automation maintains modeling accuracy while dramatically reducing the time and expertise required for the division process.
Solution Approach 2:
The patent replaces the manual mechanical process of dividing objects into subsystems with an automated computational system. The system uses algorithms to automatically perform the division, determine which elements belong to which subsystems, and generate the spatial models, substituting human manual work with computational automation.
2Measurement precision
If manual division of objects into subsystems is performed for acoustic analysis modeling, then modeling accuracy is improved, but operational complexity increases
Solution Approach 1:
