Abstract: With regard to the problem of determining attribute weights in multiple decision making，in which the attribute values are in form of intuitionistic fuzzy number，a new method is proposed to determine entropy weights of intuitionistic fuzzy number.According to the traditional concept of entropy weights，a formula is used to get entropy for intuitionistic fuzzy number and then the attribute entropy is obtained by a formula.And the attribute weights are determined on the basis of traditional formula of entropy weights.Furthermore，score function is used to get the priorities of alternatives.Finally，an example is used to illustrate the feasibility and effectiveness of the proposed approach.

摘要： 针对属性值以直觉模糊数形式给出的多属性决策中确定属性权重的问题，提出了一种直觉模糊数熵权的确定方法，依照传统权熵的确定方法的思路，通过一个公式求得直觉模糊熵；然后求得属性的信息熵；根据传统熵权确定公式得到属性权重，进而利用得分函数对方案进行排序；最后通过算例说明该方法的有效性和实用性。
