“…There are many classical and extended decision rules designed for multi-criteria decision making under uncertainty, e.g. [1], [2], [7], [8], [11], [13], [20], [24], [25], [28], [29], [34], [36], [40], [41], [42], [45], [48], [49], [50], [51], [56], [57], [58], [61], [62], [63], [65], [66], [71], [74], [75], [76], however the majority of the methods refer to probability calculus. Hence, those contributions are not directly related to the topic investigated in this paper, since here we concentrate on totally new decision problems for which frequencies are not known.…”
