摘　　要：三支决策理论是决策粗糙集理论的推广,它同样可以应用于覆盖粗糙集理论的决策分类。论文借鉴三支决策思想,利用矩阵形式,提出了协调覆盖决策系统下的一种新的多类分类矩阵模型计算方法。首先给出协调覆盖决策系统和三支决策的有关定义,然后将延迟决策类的多类分类模型运用到协调覆盖决策系统中,提出了一种新的协调覆盖基于三支决策的多类分类矩阵模型,减少代价参数,降低决策风险,最后通过一个实例分析验证此方法的有效性和可行性。Three-way decision is a generalization of rough set theory,which can also be applied to decision classification in the covering rough set theory.In this paper,a new multi-category classification matrix model is proposed based on three-way decision.First,the related definitions of coverage decision system and three decisions are given,and then,the delayed decision classes of multi-category classification model are applied in covering decision system.A new consistent covering multi-category based on three-way decision is proposed,cost parameters and decision risks are reduced.Finally,and it shows the effectiveness and feasibility by an example for this method.
