A Threat Assessment Algorithm Based on AHP and Principal Components Analysis

AbstractIn allusion to the shortage of traditional analytic hierarchy process in the determination of weight coefficient, a threat evaluation model based on the principle components analysis and analytic hierarchy process was proposed in the article. The subjective and objective factors were comprehensive considered. The importance of each index in index layer obtained by the principal components analysis method was used to gain the judge matrix in the analytic hierarchy process to improve the veracity and rationality of the judge matrix. The simulation proved that the threat assessment result of anti-warship missiles to warship obtained through the threat assessment algorithm based on AHP and the principal components analysis was objective and reasonable
