Wheels within Wheels: Making Fault Management Cost-Effective Goldszmidt, Moises Malek, Miroslaw Nadjm-Tehrani, Simin Narasimhan, Priya Salfner, Felix Ward, Paul A.S. Wilkes, John Fault management cost-effectiveness Local design and optimization of the components of a fault management system results in sub-optimal decisions. This means that the target system will likely not meet its objectives (under-performs) or cost too much if conditions, objectives, or constraints change. We can fix this by applying a nested, management system for the fault-management system itself. We believe that doing so will produce a more resilient, self-aware, system that can operate more effectively across a wider range of conditions, and provide better behavior at closer to optimal cost. This document summarizes the results of the Working Group 7 - ``Cost-Effective Fault Management'' - at the Dagstuhl Seminar 09201 ``Self-Healing and Self-Adaptive Systems'' (organized by A. Andrzejak, K. Geihs, O. Shehory and J. Wilkes). The seminar was held from May 10th 2009 to May 15th 2009 in Schloss Dagstuhl~--~Leibniz Center for Informatics.
