AI Techniques for Software Requirements Prioritization

no code implementations2 Aug 2021 Alexander Felfernig

Aspects such as limited resources, frequently changing market demands, and different technical restrictions regarding the implementation of software requirements (features) often demand for the prioritization of requirements.

CoreDiag: Eliminating Redundancy in Constraint Sets

no code implementations24 Feb 2021 Alexander Felfernig, Christoph Zehentner, Paul Blazek

For example, redundant constraints are specified which often increase both, the effort for calculating a solution and efforts related to knowledge base development and maintenance.

Towards Utility-based Prioritization of Requirements in Open Source Environments

no code implementations17 Feb 2021 Alexander Felfernig, Martin Stettinger, Müslüm Atas, Ralph Samer, Jennifer Nerlich, Simon Scholz, Juha Tiihonen, Mikko Raatikainen

Requirements Engineering in open source projects such as Eclipse faces the challenge of having to prioritize requirements for individual contributors in a more or less unobtrusive fashion.

An Efficient Diagnosis Algorithm for Inconsistent Constraint Sets

no code implementations17 Feb 2021 Alexander Felfernig, Monika Schubert, Christoph Zehentner

Another example is the engineering phase of a configuration knowledge base where the underlying constraints can become inconsistent with a set of test cases.

Consistency-based Merging of Variability Models

no code implementations15 Feb 2021 Mathias Uta, Alexander Felfernig, Gottfried Schenner, Johannes Spoecklberger
