Variability modeling in software product lines

Kaşıkçı, Barış Can Cengiz
Software product lines provide enhanced means for systematic reuse when constructing systems within a particular domain. In order to achieve this, systems in a product line are expected to have a significant amount of commonality. Variability is what distinguishes these systems from one another and is spread across various product line artifacts. This thesis focuses on modeling and managing product line variability. The concept of concerns is proposed as a means of variability modeling. Another proposal is related to the use of context free grammars to represent product line variability and to guarantee that any application derived according to the variability framework thus defined will be a valid one. This approach is evaluated for an example domain, in the light of novel evaluation criteria that are also introduced in the scope of this thesis.


Non-functional variability management by complementary quality modeling ın a software product line
Gürses, Özgür; Bilgen, Semih; Department of Electrical and Electronics Engineering (2010)
Software product lines provide the opportunity to improve productivity, quality and time-to-market of software-based systems by means of systematic reuse. So as to accomplish systematic software reuse, elicitation of commonality knowledge is to be upheld by the analysis and management of variability knowledge inherent in domain requirements. Considerable effort is devoted to the management of functional variability, often neglecting the impact of quality concerns originating from non-functional requirements...
Testing effectiveness and effort in software product lines
Çöteli, Mert Burkay; Bilgen, Semih; Department of Electrical and Electronics Engineering (2013)
Software product lines (SPL) aim to decrease the total software development cost by the help of reusability and variability. However, the increasing number of variations for the delivery types of products would result in increasing cost of the verification and validation process. Total testing cost of development can also be decreased by reusing test cases and scripts. The main objective of this study is to increase testing effectiveness while minimizing testing effort. Four different cases consisting of As...
Hierachical variability management in software product lines
Atasoy, Mehmet Erdem; Doğru, Ali Hikmet; Department of Computer Engineering (2013)
Software product lines (SPL) aim is to analyze commonality and variability of product family although SPLE describes much kind of processes in different abstraction levels. In this respect, numbers of variations are increasing for the types of products so that may result in increasing cost of the managing variability process. So that variability models is used to manage variabilities in software product lines. Representing solution space variability in an understandable way in software product line engineer...
Software subcontracting success: a case study on the relationship betweeen project success and process metrics
Yücetürk, Kerem; Bilgen, Semih; Department of Information Systems (2005)
While software subcontracting is a common business transaction in the information technology field, metrics specifically aimed at effectiveness of software subcontracting arrangements are not commonly available. This thesis makes a review of the literature and derives such metrics from fields of software quality, COTS acquisition and IS success. A case study is performed on software subcontracting projects of a Turkish defense contractor, and the project metrics are compared according to their success. The ...
Feature modeling and automated analysis for an embedded software product family
Fedakar Gönül, Gülseren; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2013)
In the context of software product line engineering, feature models are used for modeling variability and commonality in product families. This thesis presents a basic feature model for a commercial television set product family. This work consists of three stages. First, a feature model is constructed, based on the analysis of the product family requirements. The constructed model is supplemented with a feature glossary. FeatureIDE is used as the model editor. Feature attributes, not supported by FeatureID...
