To analyze the connotation and extension (C&E) of grey theory

There is plentiful connotation buried in extension, and we thus need a tool to mine the connotation. The Connotation and Extension (C&E) of the theory pioneered in this paper is just as such a tool. The connotation, nuclear connotation and extension in grey relational analysis (GRA), grey model (GM), decision making (DM) are mined such as the generalized energy system (gns) in GM, written as C11{gns}; ordering (ORD), grey relational grade (GRG), grey relational coefficient (GRC) in GRA, written as graC={GRD, ORD, GRC). Nuclear connotation is essential to the mathematics resource.
