Model development is a research area focused on creating mathematical or computational models to represent and analyze complex systems or phenomena. These models can range from simple theoretical frameworks to sophisticated simulations that incorporate data from various sources. Researchers in this field work to develop models that accurately capture the behavior of the system they are studying, allowing them to make predictions, test hypotheses, and gain insights into the underlying mechanisms at play. Model development is used in a wide range of disciplines, including physics, biology, economics, and engineering, to address a variety of research questions and problems.
