Design and implementation of a cognitive decision architecture

This paper introduces a cognitive decision architecture (CDA) which seeks to support a wide range of decision making systems. The architecture is consisted of three layers: cognitive layer (CL), individual decision layer (IDL) and group decision layer (GDL). We utilize a typical symbolic cognitive architecture-Soar as the underlying infrastructure of CDA. Decision table of rough set theory is used to describe the knowledge base of individual decider. A “voting” mechanism which is drawn from the decision experience of human society is designed at the group decision. Related experiments show that CDA is appropriate for designing large and complex decision systems.
