Product Line Engineering with UML 1

The Unified Modeling Language (UML) is a standard language for the object-oriented analysis and design. We propose in this paper an approach based on the UML that supports the Product Line Engineering. We provide a set of patterns for modeling variability issues of a Product Line Architecture, we define architectural constraints for Product Line expressed in UML as meta-level OCL constraints, and we propose a method based on the use of a creational design pattern to automate the derivation process. This makes it possible to automatically derive a given product from the set of all possible ones, and to specialize its model accordingly. 1
