| Lecture Abstract |
A trisecting-and-acting model of three-way decisions (3WD) consists of two basic tasks. One task is to divide a universal set into three pair-wise disjoint regions called a trisection or a tri-partition of the universal set. The other task is to act upon objects in one or more regions by developing appropriate strategies. Three-way decisions are a class of effective ways and heuristics commonly used in human problem solving and information processing. In this talk, we will look at the fundamental issues, basic models, and applications of three-way decisions. |
