Variability Management in Software Product Lines

Software Product-Line Variability Management based on Model-Driven Engineering

A software product-line (SPL) is a family of products sharing the same assets. A product-line platform allows the derivation of distinct products within the same application domain. The use of SPLs appears to be the most effective strategy for achieving large-scale software reuse, assuring rapid development of new products with good quality levels. Enabling variability in software consists in d...

Tested Approach for Variability Management Enhancing in Software Product Line

The paper declares a novel approach for the process enhancing of managing Variability – the ability of a software system or artefact in Software Product Line (PL) to be extended, changed, customized or configured for use in a specific context – with the proper quality characteristics to mitigate its current limitations. New Variability Model and Management Functions to process its element are p...

Adding variability management to UML-based software product lines

The software product line (PL) approach promotes the generation of specific products from a set of core assets for a given domain. This approach is applicable to domains in which products have well-defined commonalities and variation points. Variability management is concerned with the management of the differences between products throughout the PL lifecycle. This paper presents a UML-based pr...

Runtime Variability Management for Energy-Efficient Software by Contract Negotiation

Improving the energy efficiency of software systems requires runtime adjustments and explicit knowledge about the system’s variability. Component-based software has inherent variability in terms of multiple implementations for components. These implementations utilize hardware resources, which are direct energy consumers, leading to a further dimension of variability: the mapping of implementat...
