Task-based Self-adaptation David Garlan, Vahe Poladian, Bradley Schmerl, and João Pedro Sousa Proceedings of the ACM SIGSOFT 2004 Workshop on Self-Managing Systems (WOSS'04), Newport Beach, CA, Oct/Nov 2004 Abstract Recently there has been increasing interest in developing systems that can adapt dynamically to cope with changing environmental conditions and unexpected system errors. Most efforts for achieving self-adaptation have focused on the mechanisms for detecting opportunities for improvement and then taking appropriate action. However, such mechanisms beg the question: what is the system trying to achieve? In a given situation there may be many possible adaptations, and knowing which one to pick is a difficult question. In this paper we advocate the use of explicit representation of user task as a critical element in addressing this missing link. pdf
