Fuzzy logic is a natural basis for modelling and solving problems involving imprecise knowledge and continuous systems. Unfortunately, fuzzy logic systems are invariably static (o...
Epistemic and doxastic modal logics (Hintikka [1962]), and the logics of theory change and belief revision (Alchourr6net. al. [1985], Giirdenfors [1988]) are used for the represen...
We slightly improve on characterization results already in the literature for base revision. We show that in order to axiomatically characterize revision operators in a logic the o...
In this paper we investigate the relationship between two prioritized knowledge bases by measuring both the conflict and the agreement between them. First of all, a quantity of co...
This paper addresses the problem of the optimal design of batch plants with imprecise demands and proposes an alternative treatment of the imprecision by using fuzzy concepts. For...
