Analysing the Linux kernel feature model changes using FMDiff

Evolving a large scale, highly variable system is a challenging task. For such a system, evolution operations often require to update consistently both their implementation and its feature model. In this context, the evolution of the feature model closely follows the evolution of the system. The purpose of this work is to show that fine...

Evaluating Feature Change Impact on Multi-Product Line Configurations Using Partial Information

Evolving large-scale, complex and highly variable systems is known to be a difficult task, where a single change can ripple through various parts of the system with potentially undesirable effects. In the case of product lines, and moreover multi-product lines, a change may affect only certain variants or certain combinations of features, making...

Extracting Feature Model Changes from the Linux Kernel Using FMDiff

The Linux kernel feature model has been studied as an example of large scale evolving feature model and yet details of its evolution are not known. We present here a classification of feature changes occurring on the Linux kernel feature model, as well as a tool, FMDiff, designed to automatically extract those changes. With this tool, we...

Efficient tetrahedral remeshing of feature models for finite element analysis

Finite element analysis is nowadays widely used for product testing. At various moments during the design phase, aspects of the physical behaviour of the product are simulated by performing an analysis of the model. For each analysis, a mesh needs to be created that represents the geometry of the model at that point. In particular during the...

Constraint solving for direct manipulation of features

In current commercial feature modeling systems, support for direct manipulation of features is not commonly available. This is partly due to the strong reliance of such systems on constraints, but also to the lack of speed of current constraint solvers. In this paper, an approach to the optimization of geometric constraint solving for direct...

Multiple-view feature modelling with model adjustment

Multiple-view feature modeling is a product development approach that combines concurrent engineering and feature modeling. It supports applications from various phases of product development, by providing an own interpretation of, or view on, a product for each of these applications. The approach can lead to higher quality of products in less...

Validity maintenance in semantic feature modeling

Feature modeling has the ability to associate functional and engineering information to shape information in a product model. Current feature modeling systems, however, are still rather tied to techniques of conventional geometric modeling systems, offering limited facilities for defining feature semantics, and failing to preserve this semantics...

Constraint-based feature validation

The feature modeling paradigm combines geometric and functional product information in one model. In an ideal product development environment, multiple views of a product in terms of features coexist. Feature validation concerns the validity of the feature information in all these views, focusing on validity specification and maintenance. This...
