On Capability-Related Adaptation in Networked Service Systems

Adaptability is a property related to engineering as well as to the execution of networked service systems. This publication considers issues of adaptability both within a general and a scoped view. The generalview considers issues of adaptation at two levels: 1) System of entities, functions and adaptability types, and 2) Architectures supporting adaptability. Adaptability types defined are capability-related, functionality-related and context-related adaptation. The scoped view of the publication is focusing on capability-related adaptation. A dynamic goal-based policy ontology is presented. The adaptation functionality is realized by the combination of Extended Finite State Machines, Reasoning Machines andLearning Mechanisms. An example case demonstrating the use of a dynamic goal-based policy is presented
