Abstract:

Aiming at the problem that the traditional Dempster-Shafer (D-S) theory cannot effectively integrate highly conflict evidence, an evidence modification method based on eigenvector and Jousselme distance is proposed. First, the decision maker combines subjective experience to give a judgment matrix based on the relative importance of the original evidence and uses the eigenvector method to solve the subjective weight. Then calculate the Jousselme distance between the original evidence to obtain the objective weight and combine the subjective and objective weights to modify the original evidence. Finally, the D-S theory is used to fuse the revised evidence body. The simulation results show that the method has fast convergence speed and high accuracy when fusing highly conflict evidence, and at the same time has good adaptability, and it solves the fusion problem of heavy conflict evidence.

Key words: multi-sensor fusion, Dempster-Shafer (D-S) evidence theory, eigenvector method, Jousselme distance
