报告摘要：

A theory of three-way decision concerns thinking, problem solving, and computing in threes. This talk will cover three related topics:

(1) the Dao of three-way decision；

(2) a reformulation of a Pawlak approximation space；

(3) granular rough sets and three-way granular approximations in a Pawlak approximation space.
