With respect to multiple attribute clustering analysis problems with uncertain interval numbers, according to the traditional FCM clustering algorithm, a new clustering analysis algorithm for solving the problems is proposed. In this paper, firstly, the multiple attribute clustering analysis problem with interval numbers is introduced. Secondly, two theorems for determining the optimal subordination and the optimal clustering center are proposed, respectively. Then, based on the proposed two theorems, calculation steps of the FCM clustering algorithm for multiple attribute information with interval numbers are presented. Also, the two theorems show the convergence of the proposed algorithm, and the characteristic of the proposed algorithm is that the optimal clustering center is exactly numerical data. Finally, a numerical example is given to illustrate the applicability of the FCM clustering algorithm proposed in this paper.
