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.
