Actionable strategies in three-way decisions.

This paper introduces actionable strategies to the trisecting-and-acting three-way decision model. We present four change-based actionable models according to action benefit and action cost. Two of the four models provide the bounds of the cost and benefit and the other two models quantify the maximum benefit under limited cost and the minimum cost for a desired benefit, respectively. We design and analyze algorithms for these models. Finally, we report experimental results to support the proposed models.
