Fuzzy structural dependency constraints in software release planning

Incremental software development is becoming an important tendency in software engineering. A software release is a collection of new and/or changed features that form a new product. Release planning for incremental software development assigns features to sequence of releases in the most beneficial way within the resources available. Release planning is a complex problem where most of the data available are usually uncertain. In this paper, we propose an approach that improves on existing methods for release planning by handling the uncertainty of data using fuzzy logic. We use fuzzy logic to model the uncertainty concerning the identification of structural dependency constraints between requirements. All the concepts and the complete approach are illustrated by a case study example.
