报告内容提要：
The objective of this talk is to study the existing approaches of ordering on interval grey numbers in the context of decision making problems. A survey of existing definitions is presented. Grey interval numbers were compared with considered methods and the results showed that some methods cannot compare numbers in some situations. Most methods are not suitable for recognizing a larger number when the nucleus of the grey numbers is the same. Also, methods are also considered in partial order and total order.
