【摘要】：为减小传统的二支决策中直接接受或拒绝决策带来的决策风险,分析问题决策的多粒度空间,研究了基于风险最小化的多粒度三支决策模型.在三支决策风险代价分析基础上,为寻求最优的粒度空间,结合不同属性特征在粒度空间中具有不同决策权重的特点,以粒化重要度和粒化决策权重为启发式信息,从多个不同的粒度层次出发,寻求风险最小的决策行动.最后针对不承诺选项中一些急需决策的现实问题,给出了基于风险控制的二支决策转化方法,并进行了具体的实例应用.
[Abstract]:In order to reduce the risk of accepting or rejecting decision directly in traditional two-branch decision making, the multi-granularity space of problem decision is analyzed, and the multi-granularity three-branch decision model based on risk minimization is studied. Based on the analysis of risk cost of three branches of decision making, in order to find the optimal granularity space, combining the different attribute features with different decision weight in the granularity space, the granulation importance and granulation decision weight are used as heuristic information. From different granularity levels, the decision-making actions with minimum risk are sought. Finally, aiming at some urgent problems of decision making in the option of non-commitment, a two-branch decision transformation method based on risk control is presented, and an example is given.
