摘　　要：运用灰色理论中的多目标局势决策方法对轴承的类型进行优选,根据要求的目标和用途对各种轴承类型的评价因素进行了研究和分析,引入熵值法来确定目标的权重。通过实例表明,添加熵值权重的多目标灰色决策方法是一种合理、可行、有效的新型决策方法。The method of the multi-object situation decision-making in grey theory is used in the type selection of rolling bearings.According to required target and purpose,the evaluation index of various types of bearing is investigated and analyzed.And the entropy method is introduced to determining objective weight.The example can prove that the method of multi-object grey decision-making that appending entropy weight is a new type decision-making method,which is reasonable,feasible and efficient.
