Incremental and commutative composition of state-machine models of features

In this paper, we present a technique for incremental and commutative composition of state-machine models of features, using the Feature House framework. The inputs to Feature House are feature state-machines (or state-machine fragments) modelled in a feature-oriented requirement modelling language called FORML and the outputs are two state-machine models: (1) a model of the whole product line with optional features guarded by presence conditions, this model is suitable for family-based analysis of the product line, and (2) an intermediate model of composition that facilitates incremental composition of future features. We discuss the challenges and benefits of our approach and our implementation in the Feature House.
