In order to overcome some shortcomings of the former analysis methods,this paper proposed a new method to analyse warships' vital force,which regarded the problem of warships' vital force evaluation as the classification problem.The technique of Support Vector Machine was applied in this method,and the calculation model predicting the vital force of the impacted warships was established.As an illustrative instance,the vital force of a warship's subsystem was calculated,which showed that the method was highly efficient and it could be applied extensively.
