Abstract
Probability theory, as a core mathematical tool for quantifying uncertainty, provides a scientific basis for decision-making by constructing probability models. This paper systematically reviews the model construction path of the basic theories of probability theory in the quantification of uncertainty. Starting from the theoretical framework of probability space and random variables, it analyzes the influence of parameter estimation methods on model uncertainty, explores the advantages of Bayesian inference in the quantification of cognitive uncertainty, and further elaborates on the application of probability models in the propagation of uncertainty in complex systems. Research shows that the fundamental theories of probability theory provide a full-chain methodology from data generation to decision support for the quantification of uncertainty, which is of great value in enhancing the reliability of models and the scientific nature of decisions.
