Collaborative decision-making method for large equipment enterprise's supplier selection with incomplete information

摘要

To solve the supplier selection problem for the large equipment enterprise with incomplete information, DEMATEL is adopted to construct the connect relationship among the evaluation index sets of each candidate supplier firstly, so we can know the mutual influence among index sets. And ANP is used to calculate the weight for each index set. Considering the incomplete information fully in the globalization market environment, D-S evidence theory is used for multi-source evaluation information fusion from different decision makers. Finally, TOPSIS is adopted to make the final order of candidate suppliers and find out the most satisfying supplier. The numerical results show that the collaborative decision-making method in the paper is reasonable and has a certain reference value in the practice.
