Abstract: Abstract Project portfolios (PPs) have various risks in the implementation process. Project portfolio risks (PPRs) management is of great importance in achieving project portfolio objectives. In this study, hyperparameter optimization of GA-BPNN model is carried out, and the optimized GA-BPNN model is used to assess the primary risks and secondary risks of PPs. The test results show that the optimized model had higher test accuracy, and the critical primary risks and critical secondary risks are identified through sensitivity analysis, so as to determine the primary risk response action and secondary risk response action. Effective PPRs assessment and response can help managers better deal with risks, and thus promote the smooth implementation of PPs and improve the efficiency of projects execution.
