UAV path evaluation method based on RE-ITOPSIS

In this paper, in order to solve the optimization problem of UAV path, an UAV path evaluation method based on RE-ITOPSIS is proposed. First, based on the various threats in the process of UAV flight, the evaluation index is established. Then, the ITPOSIS is improved by using relative entropy to measure the distance between the interval numbers, so that the RE-ITOPSIS is obtained. And the weight of the evaluation indexes is obtained by using information entropy. Finally, the eight path of UAV is evaluated and the optimal path is selected. The comparison of the evaluation results shows that the proposed method can be more accurate and effective to evaluate the path of UAV.
