Abstract: In multiple attributes decision making problem under risk, the attribute has compensation features of linear and nonlinear and the attribute values have formats of crisp numbers, interval numbers and linguistic information. Thus, a new decision making approach on the base of error-eliminating theory is proposed. Firstly, by the theory of error-eliminating, decision making attributes are divided into key attribute, important attribute and redundant attribute. Error function and maximum loss values are given on the basis of these three kinds of attributes and the type of attribute values. And then, minimum weight is given to key attribute, in this way the “one vote negation” function of key attribute is maintained and the important role of important attribute is highlight. At last, three methods of calculating the error-loss value are given, according to the different attitude about the error-loss, and the better strategy are prioritized and selected according to the expected error-loss values. Besides, the feasibility and effectiveness of this model have been proved by an example of new citizen information service project.
