Hierachical variability management in software product lines

Atasoy, Mehmet Erdem
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 engineering is an important challenge. In this thesis, a new technique is offered to configure variabilities leading to hierarchical structure. The main issue of this approach is to divide variability model into two layers which are system engineering level variability and software engineering level variability. The new models subtract a balance between formalism’s expressiveness and specific configurations of application. The products are configured by merging these variabilities which are defined in different layers. Dependencies between these two layers can be managed semi automatically using Case tools which are developed in this work.


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...
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...
Representing component variability in configuration management
Bayraktar, Gamze; Oğuztüzün, Mehmet Halit S.; Doğru, Ali Hikmet; Department of Computer Engineering (2012)
Reusability of assets within a family of products is the major goal of Software Product Line Engineering (SPLE), therefore managing variability is an important task in SPLs. Configuration management in the context of software product line engineering is more complicated than that in single systems engineering due to ”variability in space” in addition to ”variability in time” of core assets. In this study, a method for documenting variability in executable configuration items, namely components, is proposed ...
Effects of SPL domain engineering on testing cost and maintainability
Şenbayrak, Ziya; Bilgen, Semih; Department of Electrical and Electronics Engineering (2013)
A software product line (SPL) consists of a set of software-intensive systems sharing a common, managed set of features that satisfy the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way. Together with testing of final deliverable products developed within the SPL, called Integration Testing, particularly important in this context is the way individual hardware as well as software components in an SPL are tested and certified...
An Automated defect detection approach for cosmic functional size measurement
Yılmaz, Gökçen; Demirörs, Onur; Department of Information Systems (2012)
Software size measurement provides a basis for software project management and plays an important role for its activities such as project management estimations, process benchmarking, and quality control. As size can be measured with functional size measurement (FSM) methods in the early phases of the software projects, functionality is one of the most frequently used metric. On the other hand, FSMs are being criticized by being subjective. The main aim of this thesis is increasing the accuracy of the measu...
