1. SelfCon Foil no 1 Design of Self-Adaptive Systems Course introduction 2013 Rolv Bræk, ITEM

2. SelfCon Foil no 2 Objectives You shall obtain general knowledge about different principles and technical solutions for self-configuration and self-adaptation. You shall get hands on experiences with self-adaptation by developing a self-adapting application. You shall be able to critically assess and select technologies.

3. SelfCon Foil no 3 Plan Together we will investigate Self Adaptation and Self Configuration: what is it, what are the challenges, what are the solutions? General introduction for about 3 lessons. We shall use a home networked system (HNS) as case study. Each group will develop some self-adaptive components for the system. There will be workshops to present and discuss progress and solutions. Each group writes a lab report that documents their design, gives a critical assessment and discusses related work and alternative solutions for their part. Each group present their work for examiners. You may work alone or in groups of two students.

7. SelfCon Foil no 7 Self-adaptive By self adaptive we mean systems and components that configure themselves and dynamically adapt to changing environments with minimal human participation.

8. SelfCon Foil no 8 Adaptivity classes Parameter adaptation: changing values without changing components or algorithms. Compositional adaptation: Structural – changing parts and part structure Behavioral – changing behavior/types and algorithms Autonomic systems: not just adaptation, but self management, self healing,..., Self* Parameter adaptation: changing values without changing components or algorithms. Compositional adaptation: Structural – changing parts and part structure Behavioral – changing behavior/types and algorithms Autonomic systems: not just adaptation, but self management, self healing,..., Self*

9. SelfCon Foil no 9 Flexibility Degree of pre-planning: Anticipated, semi anticipated and unanticipated adaptation. Degree of pre-structuring: Pre-structured systems: adaptation is bounded to variability admitted within a system structure Dynamic component systems: no predefined system, components are dynamically deployed, linked and adapted.

SelfCon Foil no 10 System categories Many systems have some degree of self-adaptivity, but the abilities vary: Pre-structured systems: parameter adaptation and some (limited) compositional adaptation Dynamic component systems: compositional adaptation Autonomic systems: self* Many systems have some degree of self-adaptivity, but the abilities vary: Pre-structured systems: parameter adaptation and some (limited) compositional adaptation Dynamic component systems: compositional adaptation Autonomic systems: self*
