Abstract: The three-way decisions theory is formulated based on the notions of acceptance,rejection and non-commitment,which is an extension of the commonly used binary-decision model and has been widely used in many fields and disciplines.Considering that the costs of non-commitment are often the same with misjudgment in positive region or negative region,firstly,the risk of non-commitment decision was analyzed.Secondly,conversion process into two decision-making commitments was studied,and based on the minimum conversion price,non-commitment decision risk control model was given.Finally,case study shows the effectiveness of the model.

Key words: Three-way decisions,Non-commitment decision,Transformation cost,Risk control
