Abstract
In this project model-based analysis is utilized to localize weaknesses of the current architecture and support the planning and development of future service. Therefore the communication dependencies between the services are considered as well as the application systems with their interfaces. Therefore static descriptions of the architecture are extended with information from a monitoring tool about the dynamic behavior of the services (e.g. data volume and usage frequency). For the evaluation of the established architectural model, several analyses will be implemented. Performance analyses highlight parts of the architecture with a high usage. The problem-specific creation of views enables a detailed consideration of them by an architect. Using a impact analysis the effect of changes can be simulated within the model. Additional metrics to evaluate the quality of microservices will be developed. Hot spots and demands for actions can be identified by applying coloring mechanisms and the dynamic creation of architectural parts The project is carried out in cooperation with the BMW AG.

Abstract
Architecture analyses support the enterprise architecture in managing the complexity. Problem specific parts of the architecture can be provided with the creation of views. Therefore we develop concepts to define custom viewpoints and generate the respective architectural views. Based on a selection of element and dependency types the respective model is created. Additionally support maps can be used to visualize the relations between applications, business processes, business objects or organization units. This is done using a matrix representation in order to visualize the dependencies between the elements in an easy readable way. In this project we develop a concept to generate support maps from existing ArchiMate models. ArchiMate is a graphical modeling language for Enterprise Architectures. Die assignment of model elements to the rows, columns and cells of the matrix has to be done flexible according to the needs of the architect. The regarded dependencies between the elements should also be freely selectable. Analyses are supporting the architect in this task. Further possibilities to evaluate the architecture are the calculation of change effects and performance metrics. These concepts are realized for the tool Innovator, a product of the MID GmbH and while using the Model Analysis Framework (MAF).

Abstract
Enterprise Architecture Management (EAM) is one mean in order to deal with the increasing complexity of todays IT landscapes. Thereby architectural models are used to describe the business processes, the used applications, the required infrastructure as well as the dependencies between them. The creation of those models is expensive, since the whole organization and therewith a large amount of data has to be considered. Thus, it is important to make use of these models and reuse them for architecture work. The models are a solid foundation for various kinds of analyses that support the decision making while optimizing the architecture. Analyses can determine the effects of the shut down of an application or the effects of an application failure. It is also possible to quantify the model using measurements like the IT coverage of business processes or the workload of a server. The generation of views on an architectural model, i.e. the focus on a specific aspect of the model, is also the result of an analysis. An example is the limitation of the model to the processes and applications of a specific organization unit. Architectural models can also be used for planning purposes. Starting from the model of the current architecture of the organization a target architectural model is developed. The goal is then to implement the target architecture throughout the organization. The development of a target architecture can be supported by identifying different planning options and evaluating project proposals.
In this project we want to define a method for architecture optimization and develop the required techniques for the specification and execution of analyses. The method encompasses the identification and evaluation of possible change scenarios as well as the evaluation of project proposals regarding consistency of changes and goal fulfillment. The adoption of these methods is supported by several analyses. These are for example a change impact analyses, the measurement of metrics or the scoping of the architectural model according to different aspects. We want to support the specification and execution of the analyses through the development of an analysis language. Thereby we focus on reuse and generic definition of the analysis. Using a generic meta model as foundation we are able to abstract from the great variety of used meta models in the EA domain. The execution of the analyses is done using Semantic Web Technologies and the?Model Analysis Framework (MAF).

Abstract
?
evoIM:
Model-driven Engineering suffers from the changes of meta-models, e.g. changing standards result in adapting the model transformations and models. But changes of already specified model transformations are very error prone. Thus in this project a formalism was developed how model-transformations specified in QVT can automatically be adapted after changes of the meta-models. For more information have a look at the?Ph.D. thesis of Stephan Roser.

OntMT:
Today, model-driven development is getting more sophisticated and is used for modeling enterprises and developing application systems. To develop more and more complex systems efficiently, the trend is to intelligent infrastructure services. Since current interoperability solutions operate essentially at a syntactical level, technologies have to be developed enabling interoperability based on middleware, and development platforms have to be enriched with machine-understandable semantics. The 'Ontology-based Model Transformation’ project will contribute to these challenges by lifting syntactical metamodel description into ontologies.

Abstract
Nowadays, business and information technology (IT) of an enterprise need to co-evolve with an increasing pace in order to stay competitive. New markets and competitor shifts force enterprises to react quickly to changes and realize adequate support through the IT. However, the application landscapes of enterprises are heterogeneous, technically outdated and hardly cope with the desired speed of change of the business.
Enterprise architecture management and its respective planning discipline provides a holistic approach for improving the accompanied change of business and IT in favor for both domains. Through the creation of a model of the current enterprise architecture, current architecture for short, a common understanding of the interrelationships between stakeholders of the business and IT domain and their respective domain artifacts is established. Different target enterprise architectures, target architecture for short, allow to develop different possible future states of the enterprise and its business and IT. Afterwards, it is possible to decide for one of the different transformation paths to realize the target architecture in a purposeful way, as those changes are prone to resource bottlenecks. Many approaches provide solutions for (meta-)modeling and methodological aspects. However, decision support of enterprise architects by sophisticated means from decision theory, automatic model exploration and ranking mechanisms is still scarce.
Therefore, the thesis at hand develops an interactive approach for the generation of transformation paths to assist enterprise architects in their activities through a combination of a multi-criteria decision making technique, a graph formalism based automated planner and a formalization of the po
