The book "Trustworthy Open Self-Organising Systems" addresses the computer-assisted use of social concepts as a central aspect in realizing a novel class of socio-technical systems. These systems, which include smart grids and public display environments, consist of technical and human components that interact with each other in an open environment. In this context, heterogeneity, large-scale operation, and uncertainty in the behavior of the components and the environment are the norm. Ensuring the trustworthiness of such systems enables the technical components to interact reliably, safely, and predictably, while human users are able to understand and control these systems. The book provides comprehensive knowledge about mechanisms of trustworthy self-organization, trust models, methods for measuring user trust in a system, as well as a discussion of social concepts beyond trust, highlighting the impacts of open self-organizing systems on society.
