A Framework for Situation-Aware Adaptation of Service-Based Applications

This work presents Situation Action Networks, a new framework for modeling Service-Based Application adaptation triggered by interesting or critical situations. The framework is based on a goal model able to track at run time the fulfillment of goals. Situation Action Networks are tree-like hierarchical structures which enable goal decomposition into sub-goals and primitive actions in a recursive fashion which provides goal seeking execution plans, as a sequence of primitive actions. Situation Action Networks are dynamic and can evolve at runtime by using their inherent planning capabilities.
