“Rough集研究进展”学术研讨会（济南）

Rough集理论是处理不协调、不确定信息的有力的数学工具。自1982年由波兰数学家Zdzislaw Pawlak教授提出以来，该理论引起了
国内外专家学者的广泛关注，在诸多领域获得了成功的应用。
为了更好地了解Rough集研究的最新动向，交流当今Rough集研究的热点问题，定于2013年7月25日-7月26日在jiuyou官方网站jiuyou.com,九游（中国）有限公司召开“Rough
集研究进展”学术研讨会（济南）。本次研讨会特邀请加拿大里贾纳大学YiYu Yao教授、国内高校，特别是山东省内高校粗糙集与粒计
算研究领域的专家学者做精彩报告，围绕粗糙集、粒计算、三支决策等问题展开深入研讨。
本次“Rough集研究进展”学术研讨会（济南）主要分为两个阶段：
1.YiYu Yao教授特邀学术报告；
2.各位参会专家学者报告、交流自己的最新研究进展。

YiYu Yao教授学术报告
Granular Computing and Sequential Three-Way Decisions
Abstract:
Real-world decision-making typically involves the three options of acceptance, rejection and non-commitment. Three-way
decisions can be motivated, interpreted and implemented based on the notion of information granularity. With coarse-
grained granules, it may only be possible to make a definite decision of acceptance or rejection for some objects. A
lack of detailed information may make a definite decision impossible for some other objects, and hence the third non-
commitment option is used. Objects with a non-commitment decision may be further investigated by using fine-grained
granules. In this way, multiple levels of granularity lead naturally to sequential three-way decisions.
