| Abstract: | The advantage of the expert system based on Bayesian Network is given. The inference model based on Bayesian Network is discussed and the algorithm based on the model is presented. The Threat Level Assessment model is built using this algorithm. Simulation result shows that the algorithm is effective and is able to reflect the real threat level. |
