Abstract :
This paper presents the fuzzification process on the data warehouse attribute of decision making support system in the sphere of foreign policy, as the result of which the fuzzy OLAP-cube is obtained. For this purpose, comparative analysis of clustering algorithms was fulfilled, and then selected algorithm CLARANS was applied in clustering the warehouse attributes, using medoids obtained as the result of clustering, the values of membership functions were derived.
