Multi-criteria Decision-making Method Based on Fuzzy Number and Dempster-Shafer Evidence Theory

摘要

According to the Multi-criteria Decision-making (MCDM) problem with criterion value for triangular fuzzy number, a kind of a MCDM method based on fuzzy number and Dempster-Shafer evidence theory is proposed. By means of the ability to deal with the uncertain information of evidence theory, the method first constructs the evidence body and the Basic Probability Assignment (BPA) function. In the light of the evidence weights, the evidence is discounted, corrected and fused. Finally the sort results are deserved based on the- value of each BPA. The feasibility and effectiveness of the method is verified by the supplier selection example.
