A combination of physics-based and data-driven models can be employed to capitalize on the respective strengths of both approaches. For instance, a physics-based model can serve as the fundamental framework, while a machine learning model can be employed to enhance the simulations through the incorporation of real-world data.
Uncertainty quantification and sensitivity analysis
It is an inherent limitation of real-world data that it is uncertain. Furthermore, models have limitations. Uncertainty quantification techniques assess the level of confidence in model predictions by considering the variability in input data and model assumptions. A sensitivity analysis identifies the manner in which alterations in specific input parameters (e.g., weather patterns, fertilizer application rates) affect the model's outputs. This enables farmers to comprehend the prospective consequences of disparate managerial choices.
High-performance computing and parallel simulations
Complex agricultural systems, particularly for large-scale farms or regional models, require significant computational resources to run simulations efficiently. High-performance computing clusters can provide the necessary processing power, while parallel processing techniques can distribute the computational workload across multiple processors, accelerating simulations.
By integrating these diverse data sources and employing various modeling techniques, digital twins create a comprehensive and dynamic virtual representation of a physical agricultural system. This allows farmers to gain deeper insights, predict potential challenges, and optimize agricultural practices for improved efficiency, sustainability, and yield.
