Interchangeability for Case Adaptation in Con guration Problems

We address in this paper the adaptation of a case when a complete constraint model of the underlying problem is given. The idea is to apply methods from constraint based reasoning that allows the detection of \similar" solutions, which can be used to adapt a selected case to a new situation. We consider applications like con-guration where a complete constraint model is available. For these applications, it is often advantageous to use a case-based approach because constructing a solution from scratch requires often more interaction than taking a complete solution (case) and adapt it to t the current requirements.
