It is proved that there is a unique real polynomial function that can be used to characterize the composition operation between fuzzy operators in a quantitative model of operator fuzzy logic. Based on this polynomial function, we redefine a new quantitative operator fuzzy logic NOFL by revising the existing suggested alternatives. It can be seen that it is hard for a quantitative model of operator fuzzy logic to be both theoretically sound and intuitively acceptable.展开更多

[1] is a generalization of Robinson’s resolution principle in the first-order logic, which can be applied to a set of nonclausal formulae, i.e. a set of generalized clauses. The method can not only avoid the symbolic redundancy generated from the procedure of transforming a formula into a set of clauses, but also keep the natural description of the problem.展开更多

As a generalization of the theory of epistemic process in open logic, a formalism is also proposed to describe human reasoning with uncertain, inconsistent and insufficient knowledge, which can characterize the knowledge increment and revision, as well as the epistemic evolution. The formalism provides an explanation to the dynamic properties of human reasoning, i. e. continuous revision and combination of beliefs.展开更多
