Flexible configuration process for complex software product lines

Abstract

The necessity of producing high quality softwares and the specific software market needs raise new approaches such as Software Product Lines (SPL). However in order to satisfy the growing requirements of new information systems, we need to consider those systems as a composition of many interconnected sub-systems called systems-of-systems. As a SPL, it implies to support the modularity and the large variability of such systems, from the definition of sub-systems to their composition, ensuring the consistency of final systems. To support design and usage of such a complex SPL, we propose a new approach based on (i) the definition of a SPL domain model, (ii) the formalization of variability using feature models (FM) and (iii) the representation of dependencies between those different FM. In order to manage the complexity of this SPL we complete our approach by in one hand algorithms ensuring the consistency of the SPL and on the other hand the definition of a configuration process which guarantees the consistency of products without imposing order in user choices and authorizing to cancel any choice. This thesis presents a formalization of these works and demonstrates the expected properties of those SPL, like the control of the product line consistency with incremental algorithms exploiting the domain model topology, the formal definition and the proof of the configuration process flexibility, and the consistency concepts of the process itself. On these basis, we propose a first implementation and we validate our works on a SPL dedicated to an industrial scale system-of-systems for producing digital signage systems.
