To determine the angle and position in width direction of canted deck objectively, this paper analyzed the factors that influence the angled deck general arrangements. Principal component analysis was introduced to determine the essential factors which influence the general arrangement of canted deck. Based on several flight deck schemes of foreign mature aircraft carriers, support vector machine was introduced to regression and gain the characteristics of canted deck arrangement. The training result gained by support vector machine algorithm is more accurate than other regression methods. The regression for former Soviet Union Ulyanovsk aircraft carrier demonstrates that the accuracy and validity of this method is good.

For multiple attribute group decision-making problems in intuitionistic fuzzy theory, a new targeted consistency-adjusting method is proposed to insure the efficiency and consistency of the decision process as well as preserving the original information of the experts. To reach this goal, the new method modifies the evaluation information of the expert who has large difference with the group evaluation information in the level of attribute which differs from the traditional modification without target. By applying the new method in longitudinal position selection model of engine room in naval ships, the practicality of the method is proved. By contrasting to traditional method, it is indicated that the method adjusts evaluation information with high efficiency and little modification of original information.
