Live goals for adaptive service compositions
Luciano Baresi, Liliana Pasquale · 2010
Service compositions represent an important family of self-adaptive systems. Though many approaches for monitoring and adapting service compositions have already been proposed, a clear connection with the motivations for using such techniques is still missing. To this aim we address self-adaptation from requirements elicitation down to execution. In this paper, we propose to enrich existing goal models with adaptive goals, responsible for the actual evolution/adaptation of the goal model at runtime. We also translate the goal model with both conventional and adaptive goals, into the actual functionality provided by the system and the adaptation policies needed to make it self-adapt.
