Abstracts

Virtual Ecosystems for Smart Sustainable City-districts – an architecture perspective – Jesper Andersson

This talk will discuss architectural issues concerning establishing and operating a digital ecosystem. Digital ecosystems are becoming a foundation for value streams in multiple businesses and domains. The case we study is a smart-district platform, which shares challenges with the Smart-city.

This talk focuses on two concerns, the ecosystem’s platform architecture and architecture barriers to establishing and operating an ecosystem. We characterize sustainable product and service ecosystems in a smart-district ecosystem and discuss specific design alternatives. In a design process, certain architectural barriers impede ecosystem establishment and operation. We describe some categories with concrete examples from the case. In connection to the barriers, we describe specific architectural governance challenges and discuss some possible solutions. We discuss several avenues for future platform architecture and governance research.

Self-adaptation: basic principles and industrial usage – Danny Weyns
 
Self-adaptation enables a software system to reason about itself at runtime and adapt itself to realise a set of quality goals. Self-adaptation has been widely used in the software industry, but not necessarily known under the term self-adaptation. In this talk, I motivate the use of self-adaptation, outline the basic principles of self-adaptation, and report the results of a large-scale survey with practitioners on the use of self-adaptation in industry.
