摘要: 多粒度思想是近些年来处理复杂数据的常用方法，受多粒度思维的启发，本文结合多粒度标记信息系统的概念，提出了多源决策信息系统的广义决策函数的定义；然后利用广义决策函数讨论了协调和不协调的多源决策信息系统的最优选择以及局部最优选择，并讨论了局部相对约简。同时，给出了相应的例子来验证所提出方法的可行性。
Abstract: The multi-granularity thinking is a common method for handling complex data in recent years. Inspired by the multi-granularity thinking, this paper combines the concept of multi-granularity labeled information systems and proposes the definition of the generalized decision function of multi-source decision information systems. Then, the generalized decision function was used to discuss the optimal selection and local optimal selection of coordinated and uncoordinated multi-source decision information systems, and the local relative reduction was also discussed. Meanwhile, corresponding examples were given to verify the feasibility of the proposed method.
