Abstract

Many interval number ranking methods cannot represent
the different attitudes of decision makers with different risk
appetites. Therefore, interval numbers are expressed in the Rectangular
Coordinate System (RCS). After mining the interval numbers in the RCS,
the Symmetry Axis Compensation Factor, which is known as $$\lambda$$,
was introduced, and the Equivalent Function of the Goal Interval Number
(GIN) was deduced. Thus, the interval number ranking method considering
symmetry axis compensation was defined along with its application
procedures. Additionally, the feasibility and effectiveness of this
method were verified through examples. This method is intuitive and
simple and can represent multiple attitudes of decision makers with
different risk appetites.
