Analysis of Feature Models using Generalised Feature Trees
van den Pim Broek, Ismênia Galvão · Variability Modelling of Software-Intensive Systems · 2009
This paper introduces the concept of generalised feature trees, which are feature trees where features can have multiple occurrences. It is shown how an important class of feature models can be transformed into generalised feature trees. We present algorithms which, after transforming a feature model to a generalised feature tree, compute properties of the corresponding software product line. We discuss the computational complexity of these algorithms and provide executable specifications in the functional programming language Miranda.
