Slicing of UML models using model transformations

This paper defines techniques for the slicing of UML models, that is, for the restriction of models to those parts which specify the properties of a subset of the elements within them. The purpose of this restriction is to produce a smaller model which permits more effective analysis and comprehension than the complete model, and also to form a step in factoring of a model. We consider class diagrams, individual state machines, and communicating sets of state machines.
