Abstract

The connection degree is used in set pair analysis theory to build a new model of three-way decisions. The concept “Set pair situation” can help deal with the reliability of the new model. When the parameter “b” of connection degree function becomes 0, three-way decisions turns into binary decisions. The new model is an extension and new application of three-way decisions theory. Examples verify good effect.
