| Abstract: | With respect to multiple attribute clustering analysis problems with uncertain interval numbers, based on the traditional FCM(fuzzy c_means) clustering algorithm, a new clustering analysis algorithm is proposed. In this paper, firstly, the multiple attribute clustering analysis problem with interval numbers is introduced. Secondly, two theorems for determining the optimal partition and the optimal clustering center are proposed and proved. Then, based on the proposed two theorems, calculation steps of the FCM clustering algorithm for multiple attribute information with interval numbers are presented. Finally, a numerical example is also used to illustrate the applicability of the FCM clustering algorithm proposed in this paper. |
