- KonferenzbeitragCompositional Analyses of Highly-Configurable Systems with Feature-Model Interfaces(Software Engineering 2017, 2017) Schröter, Reimar; Krieter, Sebastian; Thüm, Thomas; Benduhn, Fabian; Saake, GunterToday’s software systems are often customizable by means of load-time or compile-time configuration options. These options are typically not independent and their dependencies can be specified by means of feature models. As many industrial systems contain thousands of options, the maintenance and utilization of feature models is a challenge for all stakeholders. In the last two decades, numerous approaches have been presented to support stakeholders in analyzing feature models. Such analyses are commonly reduced to satisfiability problems, which suffer from the growing number of options. While first attempts have been made to decompose feature models into smaller parts, they still require to compose all parts for analyses. We proposed the concept of a feature-model interface that only consists of a subset of features and hides all other features and dependencies. Based on a formalization of feature-model interfaces, we proved compositionality properties. We evaluated feature-model interfaces using a three-month history of an industrial fea- ture model with 18,616 features. Our results indicate performance benefits especially under evolution as often only parts of the feature model need to be analyzed again.
