Complex software systems are described with multiple artifacts, such as code, design diagrams and others. Ensuring their consistency is crucial and can be automated with transformations for pairs of artifacts. We investigate how developers can combine independently developed and reusable transformations to networks that preserve consistency between more than two artifacts. We identify synchronization, compatibility and orchestration as central challenges, and we develop approaches to solve them.

When models of a system change, analyses based on them have to be reevaluated in order for the results to stay meaningful. In many cases, the time to get updated analysis results is critical. This thesis proposes multiple, combinable approaches and a new formalism based on category theory for implicitly incremental model analyses and transformations. The advantages of the implementation are validated using seven case studies, partially drawn from the Transformation Tool Contest (TTC).

To understand the problems in metamodeling, this work presents an investigation of bad smells in metamodels. The core contribution of this work is the reference structure. It enables design, evolution, and extension of metamodels for modeling languages used for quality analysis. Applying the reference structure yields a modular metamodel. To be able to couple the metamodel modules in a meaningful way, this book investigates metamodel extension mechanisms.

A main property of software-intensive technical systems is sustainability. Sustainable systems need to change continuously. A change to a system element can result in further changes to other system elements. If these elements originate from different domains, the change can also propagate between several domains. This book presents an architecture-based approach to change propagation analysis of software-intensive technical systems that considers heterogeneous elements from different domain.

In software development, components are increasingly being reused, especially for the implementation of standard functionalities making software development more cost-efficient. At design time, however, it is often unclear which solution providing these functionalities fits the requirements of the software system. This work proposes a method and tool enabling software architects to automatically evaluate the effects on the quality attributes of software architectures when reusing features.

This work introduces a novel approach to keep high-level component-based architecture models consistent with source code during software development and software evolution. The approach helps to avoid architecture drift and architecture erosion, which are two well-known problems that can arise during development and maintenance of a software system. In particular, the presented approach can be used to keep instances of the Palladio Component Model (PCM) consistent with Java source code.

This work presents an approach for the architecture analysis of energy efficiency for static and self-adaptive software systems. It introduces a modeling language that captures consumption characteristics on an architectural level. The outlined analysis predicts the energy efficiency of systems described with this language. Lastly, this work introduces an approach for considering transient effects in design time architecture analyses.

When complex IT systems are being developed, the usage of several programming and modelling languages can lead to inconsistencies that yield faulty designs and implementations. To address this problem, this work contributes a classification of consistency preservation challenges and an approach for preserving consistency. It is formalized using set theory and monitors changes to avoid matching and diffing problems. Three new languages that follow this preservation approach are presented.

Diese Arbeit stellt neuartige Konzepte zur effizienten Entscheidungsunterstützung in der Rekonfiguration software-intensiver technischer Systeme mit limitiertem Wartungszugriff vor. Entgegen rein redundanzorientierter Ansätze, basiert die verfolgte Methodik auf der prädiktiven Vorausberechnung adäquater Konfigurationsalternativen im relevanten Lösungsraum. Das Wissen über Konfigurationsbeziehung wird frühzeitig manifestiert und zur autarken kosteneffizienten Abwägung der Alternativen eingesetzt.
This work presents novel concepts for efficient decision support in reconfiguring software-intensive technical systems with limited maintenance access. In contrast to purely redundancy-oriented approaches, the proposed methodology is based on the predictive pre-calculation of adequate configuration alternatives in the relevant design space. The knowledge about configuration relationships is manifested early and used for the autonomic cost-efficient assessment of configuration alternatives.
