【 摘 要 】

How to reasonably calculate index weight is an important topic in target situation assessment and other information processing studies. The traditional method is to obtain the subjective weight and the objective weight respectively, and then calculate the summation by multiplying the given coefficients. However, the traditional method is constant weight summation, which could not adjust under different situation and easily lead to unreasonable result, and the coefficients are difficult to determine. This letter presents a twice variable weight strategy. The strategy could provide a better consideration of subjectivity and objectivity without additional coefficients, and adaptively adjust index weight as the situation changes. Experimental results demonstrate that the target situation assessment based on the proposed strategy is more reasonable than that under constant weight.
