Abstract: A new dicernibility matrix of inconsistent covering decision system based on generalized fission idea and some pertinent elementary knowledge are proposed.The corresponding attribute reduction algorithm and explaination analysis are studied.It is compared with other algorithms based on discernibity matrix and the advantages and applied values of this proposed method is analyzed.
