Abstract :
Default reasoning and approximate reasoning can both be handled in the framework of possibility theory. This article first restates and contrasts the two approaches. Then a preliminary discussion of the modelling of fuzzy default rules is provided. A fuzzy default rule is a default rule, such as “small birds fly”, or “flights are usually not much delayed”, whose expression involves gradual properties
