Search and Adaptation in a Fuzzy Object Oriented Case Base

In this paper we propose to represent a case using an object oriented model that enables the description of imprecise knowledge using possibility distributions. The proposed search process is based on this modeling and a fuzzy similarity measure is defined. The adaptation process is achieved with propagation of domain constraints in a neighborhood of the retrieved case. We propose a method to define this neighborhood. We illustrate our proposition by an example in the field of machining operation configuration.
