Abstract [en]

Due to the increased usage of electronics and software the complexity of systems such as automotive as well as their development process is also increasing. One possible solution to reduce and manage this complexity is model-based and component based development approach. One of the major key features of model-based development is model transformation. This report presents an effort towards the model-based development in automotive systems with a dynamically self-configuring middleware as case study. A mapping scheme from UML™ (Unified modeling language) to SimEvents™ an extension of Simulink® for discrete event simulations is the major outcome of this work. The focus of this work is on the behavior of the middleware components specified by state machines and activity diagrams using UML™. Identification of the requirements and challenges in model transformations for self-configuring systems and a library for the middleware core services for SimEvents™ is also part of this work.

Abstract [en]

With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. This promises not only to reduce the time to market but also increase the development and maintenance efficiencies. Moreover, the possibility to adapt system behavior and structure by software can improve the overall traffic infrastructure, increase robustness and safety and at the same time enable changeable user defined configurations and addition of new features throughout a vehicle's life cycle. However, the dynamic configuration management characteristics increase software complexity and provide new failure modes. Therefore, there is a need for appropriate development support.

This thesis addresses model-based development and dynamic configuration management for automotive systems in context of the DySCAS project. The framework for dynamically self-configuring middleware from the DySCAS project is the main object of study. The major focus is on algorithms for dynamic reconfiguration, model transformation, modeling and simulation. Requirements for self-managing systems with self-configuration, self-healing, self-optimization and self-protection characteristics and the simulation platforms for early analysis, verification and validation are also identified. A mapping scheme from UML™ to SimEvents™, evaluation of tools for simulating self-managing systems, simulations of dynamic reconfigurations and a foundation for a complete simulation environment are the major outcomes of this thesis.
