摘　　要：三支决策模型是近年来提出的一种新的决策理论,双论域信息系统下的三支决策是目前的研究热点。针对双论域信息系统的动态更新问题,提出一种双论域三支决策模型的增量式更新算法。对于双论域信息系统两个论域的动态变化,分别研究三支决策模型中三个区域的增量式更新。基于这种更新机制提出对应的增量式更新算法。仿真实验表明,与非增量式的更新算法相比,该增量式更新算法具有更高的动态更新性能。The three-way decision model is a new decision theory put forward in recent years.The three-way decision under two universes information system is a hot topic at present.For the problem of dynamic updating of two universes information system,an incremental updating algorithm based on three-way decision model with two universes is proposed.The incremental updating of the three regions in the three-way decision models was studied respectively when the two universes of the two universes information system were dynamically changed.Then a corresponding incremental updating algorithm was proposed based on this updating mechanism.The simulation experiments show that compare with the non-incremental updating algorithm,the proposed incremental updating algorithm has higher dynamic updating efficiency.
