Multi-expert opinions combination based on evidence theory

An approach is presented to multi-expert's opinions combination based on the Dempster-Shafer evidence theory. In the method, we use multi-expert's knowledge as evidence, the possible value of weight as frame of discernment, expert's evaluation to a weight on frame of discernment as basic probability assignment, and use D-S rule combining to give fusion basic probability assignment in. Finally, the weight is given C, according to fusion basic probability assignment. The result is shown that the method can keep exactitude information, reduce conflict factor, strong degree opinion and improve knowledge quality.
