D-S evidence theory is an important information fusion method in decision level, of which the conflict measure is mportant component. However, the existing conflict measures can not proclaim the mutual difference between evidences for ack of asymmetry. Accordingly, an asymmetrical method is proposed based on the inherent asymmetry of conflict measure. y importing inclusion metric and non-inclusive factor, the method can express the difference of mutual support degrees
between evidence, and the experimental results show the effectiveness of the proposed method.
