摘要： 利用集对分析(SPA)方法，定义带有元素单向迁移不完备信息系统中集合的上、下近似，给出了不完备信息系统的单向迁移粗糙集模型及其数学结构，并通过实例说明了不完备信息系统的单向迁移粗糙集存在的意义。不完备信息系统的单向迁移粗糙集是对完备信息系统单向S-粗集和不完备信息系统粗糙集理论的完善和发展。

Abstract: Using set pair analysis (SPA) method, this paper defines the upper approximation and the lower approximation of set in a incomplete information system with one-direction transfer, puts forward the one direction transfer rough sets model and its mathematicas structures in an incomplete information system, shows the existing background and meaning of the one direction transfer rough sets in an incomplete information system. One direction transfer rough sets in an incomplete information system is perfect to the theory of one direction S-rough sets in a complete information system and the rough sets in an incomplete information system.

Key words: Incomplete information system, Transfer, Rough sets, Set pair analysis(SPA)
