Engineering Contradiction Analysis
1Measurement precision
If a simulation model is created once to predict future complex realities, then initial prediction accuracy is achieved, but prediction reliability degrades over time due to accumulated errors
Solution Approach 1:
The simulation model transitions from a static structure to a dynamic one that automatically evolves over time. The model incorporates a self-evolution mechanism that continuously adjusts its parameters and structure based on new real-world data, allowing it to adapt to changing realities and maintain prediction reliability without manual intervention.
Solution Approach 2:
A feedback loop is established where the simulation model's output is continuously compared with real-world data, and the differences (errors) are fed back into the model to trigger automatic evolution. This feedback mechanism enables the model to identify and correct its own deviations from reality, preventing error accumulation and maintaining long-term prediction accuracy.
2Device complexity
If the simulation model structure is kept fixed for stability, then implementation simplicity is maintained, but the model cannot adapt to changing real-world conditions
Solution Approach 1:
The model structure incorporates dynamic elements that allow it to evolve automatically. While the core architecture remains stable, the model's parameters, agent behaviors, and interaction rules can dynamically adjust in response to changing real-world conditions, achieving both structural stability and adaptive flexibility.
Solution Approach 2:
The simulation model performs self-evolution without external intervention. It automatically detects discrepancies between its predictions and real-world data, generates evolution strategies, and reconstructs its own components to improve its performance, eliminating the need for manual model updates while maintaining adaptability.
3Measurement precision
If manual model updates are performed to correct prediction errors, then prediction accuracy can be restored, but time and resources are consumed for continuous maintenance
Solution Approach 1:
The simulation model autonomously performs its own evolution and optimization. It automatically compares its output with real-world data, identifies errors, generates evolution strategies, and reconstructs its components without human intervention. This self-service capability eliminates the need for manual model updates and significantly reduces maintenance time and resources.
Solution Approach 2:
The model evolution process operates continuously rather than through periodic manual interventions. The self-evolution mechanism runs continuously, constantly monitoring prediction accuracy and making incremental adjustments to maintain optimal performance, eliminating gaps in model maintenance and ensuring continuous improvement.

AI summary
A self-evolving agent-based simulation system generates model evolution strategy for applying a difference between real-data and a simulation resulting value to a simulation model, and reconstructing components included in the simulation module using the model evolution strategy to evolve the simulation model when the difference between the real-data and the simulation resulting value of the agent-based simulation model does not satisfy a value in a predetermined error range.
