Sensitivity analysis of group decision making based on set pair analysis

Decision making is the basic activity in daily life. More andmore different decision methods have been developed to treat more and more complex real problems. Still, there exists a kind of decision problem which has to be quickly answered within a short period, such as project evaluation, voting, staff hiring, etc. Based on the concept of "similarity, difference and opposite" of the set pair analysis theory, in the paper, the corresponding model and its solving method for a kind of commonly used multi-level group decision problem is offered. Through sensitivity analysis on the relevant parameters, some useful results are infered which give guidance to real implementation. All conclusions and methods are interpreted together with the inferences and calculations.
