• Increasing complexity and unpredictability emerge in many modern systems, raising the need for suitable paradigms and concepts. Organic Computing principles like self-organisation and decentralised decision making are incorporated in adaptation mechanisms, reacting to changes in the environment by adapting their structures or behaviour. Due to the high complexity and scale, these systems often constitute System of Systems with adaptation mechanisms operating on multiple system levels. In one part of this Thesis, interferences due to two interleaving adaptation mechanisms, affecting common structural elements, are investigated with respect to emerging patterns and impact on macro-level behaviour of a cyber-physical case study system in the power management system (PMS) domain. In the other part of this Thesis, the vital distribution component of this PMS is replaced by an agent-based allocation system, formulated as an electronic institution, whose outcome is evaluated by agents andIncreasing complexity and unpredictability emerge in many modern systems, raising the need for suitable paradigms and concepts.

In the other part of this Thesis, the vital distribution component of this PMS is replaced by an agent-based allocation system, formulated as an electronic institution, whose outcome is evaluated by agents and used in the system's micro-level adaptation mechanism. While especially considering the mission-critical system nature, the agent-autonomy and degree of self-organisation is promoted through the incorporation of socio-economic principles and principles of distributive justice for common-pool resource allocation.…
