چکیده انگلیسی

In 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.

مقدمه انگلیسی

The threat assessment of anti-warship missiles is the foundation for the antimissile weapon system to do WTA. At present, AHP, the method of multiattribute decision and the principal components analysis are mostly using for threat assessment, and it has some success (Tian and Sun, 2005; Qu et al., 2000; Zhang, 2005; Zhu et al., 2010). Ba i et al.(2008) introduce a amelio rate AHP method which using fuzzy ntegration judgment and geminating comparing to establish the judge matrix, it has some progress to the traditional AHP method, but it is still affected by the subjective factors of expert judgment when deciding the index weight that affect the target treat degree. Hong et al. (2006) introduce a threat assessment model based on principal components analysis, it translated the original variable into principal components, which conquered the influence of subjective factors and objectively reflected the real relationship among the sample. The principal components analysis method used few principal components to do integration judgment, which was not making the best of data information. A threat assessment algorithm based on AHP and the principal components analysis is used in this article, which not only solved the influence of subjective factors, but also objectively reflected the real relationship among the sample, and meanwhile, the data information was fully used.

نتیجه گیری انگلیسی

In 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 advantages of the principle components analysis and analytic hierarchy process are effectively exerted. 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
