In order to clarify the uncertain relationship among decision-making elements such as decision-making subject,de-cision-making and decision-making scheme in the dynamic decision-making process of coping with rainstorm waterlogging dis-aster,an emergency decision-making method combining Multi-Agent and Bayesian decision network(BDN)was proposed.Firstly,a"subject-task"visualization network was constructed in stages,and the main tasks and decision-making subjects in-volved in each emergency stage of rainstorm waterlogging disaster were analyzed.Under the premise that the dynamic uncer-tainty among decision-making elements may cause decision-making risk,the Multi-Agent and BDN methods were used to ex-plore the influence relationship of each decision-making element,so as to carry out the scheme set optimization.The results show that the method has practicality and practical significance.The research results can provide theoretical reference for emergency decision-making of urban rainstorm waterlogging disasters.
