Abstract
Autonomic, or self-adaptive, systems are increasingly important. One of the most prevalent techniques is to adopt a control systems view of the solution: adding a runtime, separate control unit that monitors and adapts the system under consideration. A problem with this paradigm for system engineering is that the control and the system are loosely coupled, introducing a variety of sources of uncertainty. In this paper we describe three specific sources of uncertainty, and briefly explain how we address those in the Rainbow Project. |
