Rough Set Rules Fusion in a Multi-agent Architecture

Rules set fusion is still an unsolved problem of Rough set theory. In this paper, a novel approach is proposed based on multi_ agent architecture. There are two kinds of agents in this multi_ agent: the arbitrator agent (AA) and the rough set agent (RSA), and two concepts are defined: relativity and related object set (ROS). These rough set agents are autonomously construct its own rules based on ROS. In the procession of fusion of rules set, RSA is able to cooperate with other rough set agents in the control of AA, and modify its own rules set corresponsive. We present an example to illustrate this method.
