【Abstract】 Function singular rough sets are put forward to improve singular rough sets,singular rough sets are proposed from Z.Pawlak sets for improvement,also;function singular rough sets has dynamic characteristics and law(function)characteristics.Using dynamic and law characteristics,the concept of f-attribute interfere decomposition,f-attribute interfere decomposition vector,f-attribute interfere decomposition matrix of function equivalence class are presented;the notion of f-decomposition of system law,f-decomposition law vector,f-decomposition law matrix,f-relational matrix of system law and its decomposition system law are raised;the application of system law and f-decomposition law matrix are given also by the conceptions.The attribute of f-decomposition of system law,f-decomposition law vector and f-decomposition law matrix conform to the attribute of conjunctive normal form.更多还原
