The group aggregation approach of four kinds of uncertain preference information is studied which are interval preference order, interval utility value, and interval number reciprocal comparison matrix and interval number complementary comparison matrix. Firstly, the uniform weight model for each uncertain preference is proposed based on consistency definitions, which has the same decision-making mechanism. In order to solve the decision-making misleading problem, the weight distributing model is suggested according to the error factor. Then, the goal programming model is put forward to aggregate the group preference. The property of the model is proved. The relation degree index and the spearman rank correlation coefficient between the expert preference and the group are introduced to measure the group consistency degree.
