The DMM approach has first been suggested by Engels et al. in 2000; Hausmann has then defined the DMM language on a conceptual level within his PhD thesis in 2006. Consequently, the next step was to bring the existing DMM concepts alive, and then to apply them to different modeling languages, making use of the lessons learned to improve the DMM concepts as well as the DMM tooling. The result of this process is the DMM++ method, which is presented within this thesis. Our contributions are three-fold: First, and according to our experiences with the DMM language, we have introduced new concepts such as refinement by means of rule overriding, and we have strengthened existing concepts such as the dealing with universally quantified structures or attributes. Second, we have developed a test-driven process for semantics specification: A set of test models is created, and their expected behavior is fixed. Then, the DMM rules are created incrementally, finally resulting in a DMM ruleset realizing at least the expected behavior of the test models. Additionally, we have defined a set of coverage criteria for DMM rulesets which allow to measure the quality of a set of test models. Third, we have shown how functional as well as non-functional requirements can be formulated against models and their DMM specifications. The former is achieved by providing a visual language for formulating temporal logic properties, which are then verified with model checking techniques, and by allowing for visual debugging of models failing a requirement. For the latter, the modeler can add performance information to models and analyze their performance properties, e.g. average throughput.}}, author = {{Soltenborn, Christian}}, publisher = {{Universität Paderborn}}, title = {{{Quality Assurance with Dynamic Meta Modeling}}}, doi = {{http://nbn-resolving.de/urn:nbn:de:hbz:466:2-12420}}, year = {{2013}}, } @phdthesis{7571, abstract = {{Driven by the need for a closer alignment of business and IT requirements, the role of business process models in the development of enterprise software systems has increased continuously. Similar to other software artifacts, process models are developed and refined in team environments by several stakeholders, resulting in different versions. These versions need to be merged in order to obtain an integrated process model. Existing solutions to this basic problem in the field of software configuration management are mainly limited to textual documents, e.g., source code. This monograph presents a generally applicable framework for process model change management, which provides easy-to-use comparison and merging capabilities for the integration of different process model versions. The framework supports popular modeling languages such as BPMN, BPEL, or UML Activity Diagrams. Differences between process models are represented in terms of intuitive, high-level change operations. Equipped with a sophisticated analysis of dependencies and a semantic-aware computation of conflicts between differences, the framework constitutes a comprehensive and practically usable solution for process model change management in the model-driven development of enterprise software systems.}}, author = {{Gerth, Christian}}, title = {{{Business Process Models - Change Management}}}, year = {{2013}}, } @article{769, author = {{Biermann, Thorsten and Scalia, Luca and Choi, Changsoon and Kellerer, Wolfgang and Karl, Holger}}, journal = {{{IEEE} Communications Magazine}}, number = {{8}}, title = {{{How backhaul networks influence the feasibility of coordinated multipoint in cellular networks}}}, doi = {{10.1109/MCOM.2013.6576356}}, year = {{2013}}, } @inproceedings{8485, author = {{Spijkerman, Michael }}, booktitle = {{Software Engineering 2013 - Workshopband (inkl.
