In response to security threats to physical protection systems (PPS), monitoring their risk profile and assessing their vulnerability is an effective response. Aiming at the ambiguity and randomness in the assessment process, this paper proposes a vulnerability assessment method based on combined weights and cloud models. First, construct the security risk assessment index system, use the optimized mathematical model to find the optimal combination weight of the assessment index, obtain the cloud model digital characteristics of the assessment index and the comprehensive assessment cloud of the physical protection system with the help of the cloud generator, and construct the standard assessment cloud, At the same time, the final evaluation results are obtained by combining the improved cloud similarity calculation method, and finally the validity and feasibility of the model are verified by simulation experiments. The research results show that the model can obtain accurate evaluation results. Compared with methods such as fuzzy comprehensive evaluation, the evaluation method has higher reliability and better evaluation effect.
