摘　　要：三支决策将决策域分为接受域、拒绝域和不承诺域3个部分,是二支决策理论的扩展,取得了广泛的应用。由于三支决策的不承诺型决策结果也要付出代价,因此首先对不承诺型决策进行风险分析,其次研究构建不承诺型决策向二支决策的转化流程,再次给出基于最小转化代价的不承诺型决策的风险控制模型,最后用实例分析证明了模型的有效性。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.

关 键 词：三支决策 不承诺型决策 转化代价 风险控制
