Abstract
We present Fril++ an object-oriented extension to Fril. This new programming language supports the modelling of fuzzy applications by integrating a fuzzy logic programming language with the object-oriented paradigm. Fril++ includes the concept of fuzzy objects as an explicit construction in the language. Fuzzy objects are naturally related with multiple inheritance, and so we allow both of these in the language. The multiple inheritance gives us more flexibility, and in any case, the associated ambiguities are not so much of a problem in logic programming as they are in other paradigms. We also exploit the fact that information is expressed by the hierarchy itself. A Fril++ program can explicitly use the hierarchy by means of special constructions integrated into the language. Fril++ provides support for user decisions when there are several answers for a message by having a library of defuzzification methods.
