Abstract:

To cope with the problem of multi-UAVs cooperative mission decision-making, a composite method based on considering target importance and UAVs爷mission trust value is proposed. The method composes of two parts including improved fuzzy matter-element target importance evaluation and UAVs爷 mission trust value evaluation based on historical mission trust value. In the first part, the improved fuzzy matter-element target importance evaluation method is presented by improving the structure of matter-ele- ment, employing uniform membership grade function and introducing the subjective coefficients. In the second part, a multi-UAV trust network model is built up based on UAVs爷historical mission data; the computing method of direct trust value, indirect trust value and integrated trust value computation by u- sing entropy theory is put forward. According to the evaluative results of the above two parts, the current mission decision-making can be obtained. The results of simulation demonstrate that the proposed method is efficient and useful, and can meet the need of UAV mission decision-making.
