Due to advances in sensing technology\, a massive amount of observational data is collected from various aspects of the system. Calibrating digital twins with the observational data is crucial to enabling them to accurately replicate the physical system. One way to calibrate digital twins is through parameter calibration. This study develops quantitative calibration methods that harness the full potential of big data\, addressing research challenges posed by its scale and complexity. These include: (a) developing an approach that integrates nonlinear optimization with statistical theory to guide the sequential design of computer experiments\, (b) devising a stochastic dimension reduction method for high-dimensional simulation parameters with explainability\, and (c) extending the framework to accommodate a wide range of problems\, including functional calibration. The approaches are validated through real-world case studies.
