The combination of conflicting evidences of multi-Agent decision was studied based on knowledge fusion in virtual environment. The error, unanti-resutt was caused by normalized constant in the Dempster-Shafer theory. The combination of evidence in Dempster-Shafer theory was transformed formally that the formula was disassembled into two terms and the normalized constant was also disassembled. The second term contains an unknown. So a new improved combination rule with equivalent method was proposed and the concept of the errors of the fusion wa...
